Title: carburetor problems
Post by: JonzWagon on May 17, 2018, 06:34:52 PM
Hi. Looked for answers, but no luck. I am having a carb problem and I need to have it rebuilt or replaced. HOWEVER I have not been able to figure out what kind it is or anywhere to get one or even a rebuild kit. I assume it is a Holly of some sort??? The car is a 1980  wagon with automatic trans and California smog stuff attached. Which I was told makes the carb different than others. Is there a way to identify it?  I keep finding numerous holly 2 bbls with many different apps. The car runs and idles ok, but, has no low speed power.  barely gets up my driveway. I was thinking accelerator pump problem, but don't know if it applies to this carb. If I can find a replacement one that would solve many problems.  Any advice or suggestions would be greatly appreciated.  Thanks for reading this.   John

John , this one has too many possibilities, first verify that all of the CA smog equipment is properly hooked up, Then look for a possible EGR issue, ( Stuck open) . If you remove the air cleaner and watch for the accelerator pump jets when you activate the throttle, you may be able to eliminate that possibility. Put a Vacuum gauge to the intake manifold and get a reading at idle, and then watch when the throttle is opened. The gauge should read a steady 11 to 17 inches of vacuum at idle and drop as the throttle is opened. A fluttering  or low reading at idle is the first clue. More after the verification of fuel , pumps squirting , and elimination of vacuum leaks that may be present. There could be stuck temp control TVSS vacuum valves  issues too. More on that later.
 Start with the basics ..

Pintosopher... ..........Many thanks for the advice.  Will go thru your ideas this weekend. I will check the CA smog set up. It has been 4 years since I was in CA. and had to pass a test.  I know where to borrow a Vac Gauge so  thanks again you got me started on what to look for.  John
