Body Damage is Cool
The Weber is a much simpler carb, has far fewer parts to fail or cause problems, and might give you a small performance boost over what the factory carb is capable of. If you don't have to worry about a visual emissions inspection then that would be my choice.

Might be a bit late, but have you plugged the line that goes to the charcoal canister? I've forgotten what its called but that valve goes bad and causes it to hardly run. BTDT.

And, Weber.

Yes, the infamous bowl vent valve failure. Try that first.

Bowl vent valve. Eddy beat me to it of course but while I was working it popped in my head! Yeah try that. Locate the big hose coming from the carb and meeting up with a hard line above the exhaust manifold area. Plug it (I used a drill bit lol!) and give your truck a spin.

Before I did that, my truck would have bouts of being powerless, like it wasn't getting fuel. It would cough and sputter and sneeze. Plugged that > new truck. Still need to re-carb it with a weber, but it drives fine now.

Nope, not that.

However, upon further inspection I noticed a hole in the intake. I thought, that's not right. Looked at the engine in my garage and hey presto! Swamped the part, fired it up and it runs a treated! <img src="/forums/images/graemlins/kewl.gif" alt="" /> I plugged the vacuum line because I guess it goes to the stock air cleaner assembly? It turns out that the twit who put the aftermarket air cleaner on plugged the hole with a rubber bung that must have popped out! I will put a sock air cleaner on at some point. My guess is that works much better.

OK, the power sucks. I know it's no powerhouse, but this is bad. I lost all the carb settings messing about with it. However, I set the timing and idle speed. Then I adjusted the mixture screw to the highest rpm and then reset the idles speed and checked the timing. This is what the FSM appeared to describe.

Assuming I am starting from scratch, how do I set the carb up? Ejumicate me <img src="/forums/images/graemlins/cyclops.gif" alt="" />

That's about all you can do. Is the choke opening when warm? Test the secondary butterfly vac can by pulling off the hose and see if the can holds vac. I put on an extending hose and suck on it and see if the vac holds.
