Thanks for input but everything checked out ok on timing, dwell angle etc etc...As the saying goes, most carb problems are electrical. Check and or replace coil, rotor , ignition timing etc, etc. It’s difficult to set the carbs correctly unless you have a lot of experience. Might be worth on a rolling road specialist.
Misunderstanding....of course I reset the tappets. All 12thou.So correct me if I’m wrong but ......you had the head skimmed (ie removed material) you bolted everything back on including the rocker shaft etc and didn’t set the rocker clearance ?
what do you think has happened to your rocker clearance by skimming the head ?
