After hours of searching for a vacuum leak I still have many people telling me a hesitation in my earlier posts is most likely a vacuum leak somewhere. I have gone through 4 bottles of carb cleaner and a bottle of dish soap but its either got to be a vacuum leak or the carb itself. Most of my vacuum hoses I have taken off has absolutely no suction at all. I am wondering if there is a certain amount of psi I should be getting from my vacuum lines or if it is different depending on where it is at and so on. I am actually just trying to find another method to judge weather or not I have a vacuum leak. Carb cleaner isnt working, soapy water isnt working. I am not finding any weak or cracked lines, but I am hearing its a vacuum leak more than anything so yeah. If anyone has any other ideas on how to find a leak without spending over $1000 I don't have for a smoke machine.

 

how old is the carb? if you dont know, rebuild it. Its easy, fun, you'll learn a lot, costs about $30 for a kit and cleaner, and then you'll KNOW its not the carb. Also, then you can strip it, make it better, and get rid of your rats nest and have less than half of the vac lines lol

 

I have rebuilt it a couple months ago but being my first time rebuilding it theres a possibility I may of done it wrong, and I also got rid of the rat's nest already also lol.

 

With the engine off, look down into the carb and engage the throttle. Look to see if the accelerator pump is squirting throughout most of the range of the throttle. I have had symptoms that seemed kinda like a vacuum leak but it was actually fuel delivery. Missing one of the check ***** or weights for the accel pump is a common mistake on the rebuild and would cause hesitation.

 

How many check ***** are there supposed to be? I put one in where there is a screw and a weight then a check ball under that but that is the only check ball I could locate on the carburetor.... That may be a problem lol

 

Scratch that.. found a diagram and saw where the other check ball is supposed to be. Turns out I was missing it, unfortunately though that isn't the only problem because I put it in and the car is still doing the same thing lol.
