RE: engine tuning - first run - bogs
My FH started right up in 3 pulls and ran well but during the first run it also bogged but not near enough for the car to shutoff. In my case I found that the richer I made the lowend needle the less lowend bog I had. After I richened up the lowend needle I had to turn up my idle screw to keep it idleing correctly.
Funny thing is on at least my motor you don't need to move the needles very far to see what the motor is doing. A little too far in any direction on the needle and the car lets me know right away by bogging badly or hesitating. With my stock pipe or my Jetpro.
