Car dosent go more than 75 milles

[hondalx85]

hi guys i have a honda accord 85 hatchback lx, the car has a great shift to start, in 1 gear i can go like 18 milles, at 2nd like 45 milles, at 3rd like 60, at 4rd like 70 but at 5 the car onluy goes like 75 or 80. i allready clean up the carb, im using bosh spark plugs platium 2, only need to change the oil, but y can go over 90 in descent

Do you mean 75mph? What's the car do when you hit that speed? Maybe your timing is off. Also, did this happen after you put on that intake?

I like your car thouhg. Looks clean and nice work repainting the bumpers and the black trim. That's the proper attention to detail I like to see, that really helps the car look like a million bucks.

lol sounds similar to my woes

[carotman]

Maybe the secondary barrel on the carb isn't opening.

[hondalx85]

the car only gets like 75mph and if a get lucky 85 mph, only goes like 3500rpm in 5th gear. since i remember that is the top speed i can get of the car, i have about 9 year whit the car. for my next proyect i want to rebuilt the engine, only changing all the gasket from the heat and up, i hope thats help the car because the motor has some oil leak. im going to post more pictures so you can see the conditions of the motor and i will put a video to see the speed im geting.

Mine does this even with the Weber I just installed. 75 is the absolute fastest it willl happily go. Any forcing beyond that makes the motor just heat up and get all matters of pissed. But there is no sign of a problem in the lower gears, it pulls like a freight train and slaps the red line in 1st and 2nd gear. Then third u can only rev to 3500 under heavy throttle, if you wind it out slowly with a ginger foot u can rev it to 4.5 or so, 4th about the same, 5th about the same.

So not only is it speed limiting but hills are also a major problem haha

THE MYSTERIOUS POWER WALL!!!

[hondalx85]

i remember one time going like 90 or 95 down a hill but the car was at is maximum power, i think the extra weight in the car help me to get to that speed. the god thing is that my car dosent heat up, i put the air hose that is located in the headers directly down the car, so when the car starts to run allways is geting air. i will post a video so you can see.

Do your brakes get hot? Have you eliminated a dragging parking brake or sticking caliper.

[2ndGenGuy]

Yeah check and make sure your secondary is opening in the carb. When these carbs sit for a while, or you have grandma driving them for a couple years, the secondary won't get used and will freeze up...

[hondalx85]

i will check that, but is strange because i make the full kit to the carburetor like 2 months ago, but maybe is the carburator that is damage or someting because a get arround 16 or 18 mpg on city and on highway i get like 23 mpg. i get a good start, still burn tire on 2nd gear, but i will check the carb. i feal like driving a 6 cyl with the power of a 4 cyl car.

accord83: the brakes are fine, i changed like 3 months ago, the problem of the speed is since i got the car like 8 year ago. i was tinking maybe the car has a speed lock to run that speed but is an old car how you can do that.

Let us know what you find out. The secondaries on this car are vacuum actuated, so if you have a leak, or crossed vacuum line, or improper reassembly of the carb, it could cause the secondary circuit to fail. I had an old carb that had been sitting around for awhile and the secondary butterfly rusted to the barrel. Also, PLEASE GET RID of those Bosch plugs, they are no good in any Honda. Get yourself a set of NGK plugs, you will thank me later. Your milage seems rather poor too. I would usually get about 34mpg highway in both my 84 and 85. About the speed thing... I got my 84 4dr 5 speed up to 115 mph without too much effort and my 85 LX 4dr 5 speed up to 105. I never revved the 84 past redline but it would get there without any problem, the 85 on the other hand would regularly piss me off so I would rev it to 7 grand all the time and it took it like a champ. I know... that's auto abuse, but it asked for it. I revved the 85 to 8 grand one time when I was pissed at it and it seemed to take that ok too. Now don't go trying to rev yours that high, it is not recommended, my 85 ran like crap all the time so I really didn't care. It's kind of a do as I say and not as I do type thing.

[2ndGenGuy]

Damn dude, how many 2nd gens have you had?

[hondalx85]

i will change the spark plugs today and an oil change to, i allready have video of the car but i cant find the cable of the camera, i will try to post the videos in the night or tomorrow. i have one at normal drive 4th geat like 55 mph and 5th gear like 75-80 mph, and i have another forcing the motor at 2nd gear like 45 mph and 3rd gear like 65 mph i have to stop due to trafic but i was planning to get like 80 in 4th gear, the problems is the 5th gear. but first i will make some tune up and tested.

is hard to record and drive at the same time with a 5 speed car, i will sit my brother in he back so i can record a better video

in this video i only touch the acelerator in neutral and it goes at 4000rmp, i now is a crappy video but i will post more videos.

Well... I had a white 84 Std 4 door 5 speed, a tan 85 Std 4 door auto, a dark blue 85 LX 4 door 5 speed and my current brown 85 SE-i 4 door auto.

[chuck d]

Iv'e had 4 82/83 Accord 5spd HB. All pretty much stock with 'that' carb.
The only one that Really went very fast was originally from Colorado. The other 3 from Cali.
The Colorado had Much more power, in every gear, But you could really notice it in 4th and 5th.
I don't know for sure if it had the High Altitude carb (didn't know how to tell) but it was a Colorado car, and did Not have Ca. smog shat.

my step dad got clocked by the po po going 100mph in my old 82 .. it had a rebuilt carb were they did something worng on start up it would running really rich and spit raw gas out the back but managed to get 50-58mpg but it was just as fast before the carb was rebuilt

it had well over 200k miles on it (Was almost at 300 when we were getting rid of it) only time it ever showed problems with power was going up hill... i would do a compression check if thats fine get the carb rebuilt and a full tune up

[Ichiban]

There's no way on this planet an 82 accord got 50 mpg on a carb spewing gas. My 1.6 doesn't spew any gas (except when it goes into float sticking phase) and I top out at about 31 mpg. Time to wipe the bullshit off of your calculator.

no lie and it only ran rich on first start up in the am.... i still have no idea how the hell it did it but we ran it dry sevreal times doing tests on it... was all highway tho and flat land (lived 60 miles away from any town )

That's a sweet ride you have there hondalx85. Whenever I hear a "no power, don't know why" thread, I think exhaust restriction. This is especially true when the power tapers off as the engine load increases. If it were my car, I'd start with that fart can. Go back to factory exhaust and you might find things all working much better.

That is a great point. A restricted exhaust system or plugged cat could be the culprit. I remember on my buddy's 93 Integra, he had a plugged cat and it had no power under heavy throttle or at high rpms. He installed a new cat and it was 100% better. I agree going back to factory exhaust is a good idea and it will help you regain some low end torque. The only time an aftermarket exhaust is a good idea is if you have a heavily modified engine.

sorry for the delay, i was on vacation. i allready make the tune up on the car, change spark plugs, spark wires, motor oil, and only get to 90 mph, i remove the catalic in 2003 and install a resonator, is to reduce all noise, but i still geting to low the MPG i only get like 16 MPG, whit a full tank i get arround 220 miles. its strange because i dont loose any power on the car, it runs great but i dont now why im geting to low fuel efficiency.

last week whet front tijuana to ensenada and no problems, the car dosent heat up, no burn oil, on the freeway get arround 90 MPH at max speed i get to 80 mph at normal aceleration and the next 10 mph forcing the car.

i notice that the carb has some fuel leak down where the fuel line conects i post 2 images i realy dont now the funtion of this part of the carb i think is the reserve fuel but i don now.



its not leaking from the fuel line

[ekoms]

I had a leak @ the exact the same spot. on mine it was that diaphragm leaking, or its the fuel cut off o-ring directly above .

[hondalx85]

i change the ignition coil and feel a little improvement on the car, i have more aceleration and tested the car and i got to 90 mph with no problem, its not to much but is beter than before, i hope that helps to my problems of fuel efficiency at least 2 mpg more

pictures of my old coil

sorry for the delay guys, im going to replace the carb because i dont find any solution to this problem, other problem that i have is with the cold weater, always in the morning i find a spark plug wet on gas and the problem is that is not always the same one, the only one that is working ok is the #1 and cant start the car. any suggestion???

[2ndGenGuy]

Man, you have one of those carb dilemmas going on it sounds like. These carbs are basically two in one. One part of the carb runs rich, and the other runs lean for CVCC operation. Now if the lean part of the carb is leaking, maybe it's causing an overall rich condition in the motor... operation of these carbs is just such a mystery... I'd say if you're getting a new carb, that's your best solution. You could have some internal diaphragm that's blown, or power valve assembly causing problems, or leaky accelerator pump.... who knows... I doubt it's anything external. I think you're on the right track...
