Float Problems
1977 L-48 Rochester M4MC
I opened up my carb to fix an old bogging problem and I noticed the float was not adjusted to specs. I adjusted it properly and it helped my problem...but some bogging still occured during instantaneous acceleration. Due to the current behavior of my car I am assuming that I should adjust my float again in order to eliminate the problem completely. Am I correct in this assumption or should I be looking elsewhere for problems? One worry I have is that I didn't truly adjust the float to where it should be because I have not mastered the art of float adjustment (the process seems kind of subjective to me). Also, is bogging during instantaneous acceleration due to a float that is adjusted too close to the top of the carburetor or one adjusted too deep into the carb?
Thanks,
Ted

Re: Float Problems (love to drive)
Could be in the vac. for the secondaries. If it's not right, your secondaries will open too quickly, causing a big rush of air with insufficient gas to feed it. This will create a lean condition and a bog....There is an adjustment screw on the RH side of the carb to adjust it, but I can never get them right or really explain it any better than that...
I'm sure somebody else can explain it better than i have....I can't answer about the float...maybe lars can help you.
