Hi guys.
I wrote a long one and it whent away..

Needing more timing to run, cars at 26 deg. Base to fire up.

Vac guage flutters from 12 to 18 rapidly on idle.

give alittle gas and vac guage steady ish at 20 vac

Slight rocker clapping

Punch the gas, runs like a top

But not realy, stinks like un burnt gas. Uses alot of gas.. runs like it lost 100 horse power..

Deap down I'm thinking a bad valve,, lifter,,
I had this issue before.

It's a roller cam, roller rockers.. car runs great if the rockers are on the loose end..

But I've replaced the lifters 2 times now...after that it's good for 2 to 4 years. Or whatever, doesn't seem right
