bogging 318

I also tried to get 0 vacuum at idle and found that without modification it is not likely. any vacuum up until the vacuum advance starts to pull in additional timing will not effect idle. Most guys here will advise you to get the max vacuum at the manifold (ie. pcv port) for idle timing. then adjust your total mechanical advance to achieve maximum total mechanical advance under WOT for best acceleration. your bog seems to be more a result of the acceleration pump than timing at this point. It should start to pump as soon as the throttle is pushed and all the way till Full throttle. It appears that the Acceleration pump has a problem pumping near the beginning of its travel. Check ball may not be installed or the piston seal is leaking. Check here first. Ethanol gas is notorious for causing problems in these carbs.
