I have Holley's, but check to make sure the little bendable rod that connects the primary shaft linkage to the secondaries is adjusted so it completely closes the secondary butterfly shaft when the carb primaries go to idle. If not adjusted correctly the secondaries are left a little open causing a lean starting condition with the engine hot. I do not believe you will not see this adjustment in any rebuild book or instructions. I never did, I noticed it when rebuilding the carbs. This fixed my problem a few months ago but never I came back on the thread to mention the fix.
