Thread: Cam installation gone bad....

Did you check for a vacuum leak????

I will tear into the carb today to clean it up. I will also check vacuum, but I should add that the motor takes an unusual amount of throttle to start it and keep it running. I have to floor it to get it to start. If I adjust the idle screw in nearly completely, it will idle around 2000 RPM when warmed up. As soon as it the Rs drop below this, instant stall.

Thanks for both of your help. I'll let you know what I find this morning.

Did the car run ok before the cam was pulled? You mention you had issues with cam lobe and lifter wear, how bad was that wear? I know you say it "ran" before putting in this one, but did it run well? If it ran ok before you did this work I can't see the carb getting plugged up unless you had it torn down for a very long time.

I'm thinking either you have a major vacuum leak or you didn't get the timing chain on right. Also, this will be a dumb question, but it sounds like you have a solid cam...........are the lifters also solid for sure? Reason I ask is years ago I put in a Duntov 30-30 solid lifter cam and they screwed up and gave me hydraulic lifters. Ran like you are describing.
