tops out at 85

[mark_salad_bar]

so the question is ...why wont my car go faster then 85mph. car runs great, but i do feel like it doesnt have enough power..could it be that my fuel pump is weak? It an 89 accord lx 5spd carb.

[snoopyloopy]

try shifting to fourth? :dunno:

[Cheeseburger]

time for a tune up?

That helps but not by much. Mine can go past 85 easily and i have a 89' LX 5-speed. So try doing a tune up.

[DDRaptor]

yeah man your fuel filters are begging to be changed.

[mark_salad_bar]

my fuel filters have been changed...new plugs and wires...carb is clean...dont know what else to do.

Salad sounds delicious... :eatarrow:


Have you checked your timing?

[steveko]

Tune up my as-- sounds like the carb vaccum secondary isn't opening or it's running too lean.Or as you may have heard on this site before, there could be a vaccum leak.

[MessyHonda]

yup something sounds wrong....i can hit 110 on my dx auto.

[skycam_313]

carb adjustment please...... :D

check vacuum (u can do it with carb spray)
check venturis (for looseness)

compression check

etc etc give us a more specific explanation so we can pinpoint it

[HondaBoy]

take the air cleaner off. while running, flip the throttle on the carb to wide open and see if the secondary is opening. if not, that would likely cause you not to be able to reach a higher speed. could just be a weak diaphram opener that oporates the secondary.

you might also check the throttle cable, mine was extremely loose, and should be replaced BUT just so you know the deflection between the lock nut and the throttle plate thingy its wrapped around should be 4 to 10 mm. and actually mine is still kinda loose but like i said it needed to be replaced. just an idea, mine wouldnt go past 90 in 4th and after the throttle cable adjustment i got it to 100 but slowed down to not push my luck.

The secondary should be checked, it's hooked up to a thermovalve that if it's leaking could cause the secondary not to open.

Also check your coolant as that effects the themovalve which effects the secondary.

And check for loose booster venturies

and leaky vacuum lines.

X2 and my mechanical secondary is not fully engaged, still have throttle left

I would check the timing , tire pressure, and see how much extra weight you are carrying
also check your carb hardware as suggested ^^
also check clutch pedal free play

yeah it could be your running lean, i hit 125 in my carb'd accord lx. (4dr) your def. running lean, or just going up into the wind. i was up in ellensburg and heading up towards the hills and i topped out at 95 but going back i hit like 130 lol. so i could be where your doing it. remember there are more variables other than the car.
