Default Re: Can't get the idle right

With the aid of an unlit propane torch apply a touch of propane around the carb and intake manifold. Any air leaks will become evident with faster and smooth idle. A vacuum wiper?/can cause problems too. An no matter how old the rebuild with only 400mi. Can't be expected to idle perfectly any way, assuming that the rebuild was done correctly.
My engine didn't behave properly until it had approx. 2100 miles under it's belt.
