My 86 mighty max it running really rough just finished engine swap and I'm trying to dial everything in but a place start looking on what could be making it run so rough. When its running the whole truck is shaking
Checked ignition it's good
Check compression 140 psi and up
I Check the vacuum lines there ok
The carb my need to be rebuilt or changed I have a new ca smog carb when I put it on it didn't do nothing for my truck but make it run the same but found it had a hole in a vacuum line when I pulled the motor
I'm also thinking it my be the catalytic converter cause the smell out the tail pipe is real strong and I can hear random puffs coming out the pipe
