Re: Weber install with pics
Looks like a nice, clean, job well done! Now it's time to shine up the rest of that engine bay! :)
Re: Weber install with pics
I can never get over how much shit goes out when a weber goes in, props!
You may want to mount your regulator somewhere, e.i. on that exposed bolt hole on the back of the mani.. just fab up a bracket and it'll be solid.
Enjoy the weber!
Re: Weber install with pics
Ya most definitely, there's got to be remnants from the 80s under all that buildup. I'll do that next weekend.
I couldn't get a wine cork that was big enough to fill the a/s tube so I had to go buy a bottle of cheap champagne for the cork. I tossed the champagne and went for a pint can of guiness :beer:
Double checked all my vac; coolant, and fuel line connections, cycled my fuel pump for leaks....
After that all I did the baseline lean idle adj. and she fired right up after 5-6sec of cranking.
I have the speed screw, 1 turn in, and the mixture screw 1 3/4 out. This is as lean as the tuning guide says you should go but it still idles at 1000 with these settings. Any lower rpm, the idle starts to get rough. I've checked for vac leaks around the carb base and manifold and it does not raise the idle.
I can get it to idle down to 800-900 if i have the mix screw at 1 1/2, but its a little rough and the guide says that any less than 1 3/4 out and you need a smaller idle jet. It's nice and smooth at 1000 so I just left it that way
I haven't done anything with PCV yet, maybe its the cause? I plan on bringing it to the rear manifold vac tee. The hose size needed for this is 3/8?
Re: Weber install with pics
Thanks for the props guys, it was quite a daunting task, removing all those lines and getting the linkage to work. Also the regulator is bolted to the fender well, just hard to see. I was going to mount it to the manifold but figured there would be less vibration on the wheel well.
Re: Weber install with pics
wow so clean and almost hitchless install!
Re: Weber install with pics
Thanks man, but not completely hitchless. I cant get the damn NPT fittings on my fuel pressure regulator to seal properly. At first I used this "indian head shallac" gasket and thread sealant that I used for the adapter plate and carb gaskets. It held fine the first night when I got it running, but in the morning I checked everything again, and noticed a slow drip coming from my regulator. So I went to autozone and found a can of brush on high tack gasket and thread sealant. Removed the regulator, cleaned it and the fittings, and liberally coated the fittings and the outer edge of the female threads on the regulator, assembled, and let dry over night. Installed this morning and checked for leaks, seemed fine, let it run 5min and still no leaks. Should be good right? NO I get home from work today and check it out, lo and behold its leaking again.
When I bought the regulator it said it was a low pressure carb type reg for 3-12psi. So I figured I would just crank it all the way down and it should put out 3psi. But the pressure gauge is only reading 1.5psi and i haven't even adjusted the regulator.
I'm just going to remove the damned regulator for now and put the gauge inline when i get the fitting.
BTW What type of thread sealant have others used for fuel fittings?
Re: Weber install with pics
why was this regulator anstalled anyway?
Re: Weber install with pics
Because the Weber calls for 3psi max.
It seems to be doing fine at 1.5-2psi. without the reg. If I ever change my fuel pump I'll put it back in though.
Re: Weber install with pics
Yeah the stock fuel pump should run that Weber just fine without a regulator. I've had some regulators that were pretty much useless garbage and found it a lot less hassle to not even use one. I used teflon tape to seal fittings like that. Seems to work okay...
Re: Weber install with pics
My weber couldn't handle stock fuel pressure, so I had to put a regulator in. With that air suction pipe, or what ever you want to call it. If you leave it open like that, you will start to smell exhaust fumes. I've seen some people crimp it like you do with toothpaste. I just removed it & welded the hole shut on the exhaust. Nice set up BTW, I like that throttle set up there.
