Ok, so I have a newer engine with a summit 1104 cam. Ive been trying to tune it in, and I feel like I'm close. But I kinda have one problem, I get it to run/idle better when I have the pvc hose disconnected from the base of the carb and the carb port plugged. Is it possible that I have a vacuum leak or something along the intake? Only reason I mention this is ive forgot to put the pvc line on before and it ran like crap (different engine). I was thinking about seeing how it would run if I ran the pvc line to the intake port behind the carb where the trans vacuum line connects. Is that a bad idea? I don't have power brakes. I have a few other ideas but just seeing if anyone had similar problems in the past. It kinda has me stumped and haven't had time to try a couple of my ides. (Ive ran this cam before in a different engine similar set up, with no issues with pvc plugged into base of carb) Thanks
