hey guys, i have an 86 tII coversioned 7 and i just recently rebuilt the engine and had it street ported. and when its idleing it loaps. i checked timing and its off and cant get it adjusted properly. is this a timing isue? any help would be great.

 

hello fellow WA friend. u need RPM to be below 1000 before u can adjust timing. Find all your vac leaks, get the idle down, then adjust timing with a timing gun.

Good lucks.
