i know i dont have any external leaks, and the shutter valve is good, hows that?

well im slowly but surely getting closer, it can only be a number of things.

I got a question.....when you take off the upper part of the carb, and you have the floats attached, are they supposed to be even...i mean, the same amount of movement in each float. the one has the amount you would assume would be right, i do, and the second has virtually no movement. So i guess what i am asking is, are the two floats supposed to be the same in the movement, the same range of play?

I got out my haynes manual to see if I could help to answer the question about the floats being even. The manual does not specifically say that they have to be even, but I could not see them having to be adjusted to have different ranges of motion. The manual gives very detailed instructions on how to properly adjust your floats. Maybe that will help you some. Also, if you guys don't already know, a good way to track down a vaccum leak is with the car running spray carb. cleaner on the vaccum lines. If in your spraying, the idle jumps up quickly then goes back down, you have found your vaccum leak.

ahah sounds similar to mine... still waiting for a sunny day to go check everything, though. good luck :bigthumg: car looks good :bigok:

Hey man couple of things u can check.



If you replaced your fuel pump did you also add a pressure regulator? My replacemetn fuel pump was sending too much pressure to the carb. Fuel pressure should be about 3 psi (I think).



Vacuum leaks (That rats nest is crazy) check to make sure your hoses and such are ok.



Secondary blades on carb. Make sure that diaphram has no leak and the spring is in good condition.



Or maybe your motor is low on compression and is just getting tired..

i found part of my problem, the air pump came apart and messed up the air control valve, causing a vacuum leak. also the timing is way off, some joker put the front pulley on wrong
