Thread: 383 Stroker low vacuum and sluggish

Tweet

Yeah I’m using number 1 spark plug wire. I did your method to try and find a leak from the underside and everything seems good. I’m thinking these marks are off because engine sounds the best when it’s at about 50 degrees timing. Any lower and it starts to stutter. What’s the best method to find TDC with everything installed? Is it possible it just runs a very low vacuum?
Fuel pressure is about 5 pounds. Adjusting the carb doesn’t seem to do very much either way I turn the adjustment screws?
Also I noticed I don’t have a PCV valve hooked up on either side of the carb. Both ports are plugged.
