Some people you just can’t help, and with the history of members here that have a wealth of knowledge and a history of willingness to offer excellent help, the silence by a majority of them is deafening, can’t say I blame them though.......
but for the sake of beating a dead horse:
the timing needs to be roughly as a ballpark something around 18-20 initial and 14°-16° mechanical = 34° total, vacuum adds something like 16°-18° for 50°-52° Adjust from there.
Pull the carb, and as needed: square up the transfer slots, get idle afr set, work on pump shot, cruise afr, and check cruise vacuum and put a correct power valve in, work on secondaries, wot runs and jet accordingly. That’s the general idea.
And i might just pull the front end off the engine and check with a degree wheel etc to see where that cam is installed.
Think any of that’s been done methodically and meticulously?
