Hey everyone i'm back on here after about five years. Couldn't find anything like this, let me start from the beginning... Hydro-locked, then rebuilt head, rebuilt engine with a 20-over bore, starts and runs great and timing is spot on. but i idle at 4000 rpm. when i put in gear it drops to 1500 or so. Any ideas for an old school 2gnt'er from the gurus??
