k got a mag that when idling the right pipe ( got duels own it) is not as consistien as the left pipe ( looking from the back of motor) is this normal? If not how do i fix it ? It runs fine just wondering y it does this, thanks .

i have same thing. its not a problem, its the cam/pipes. if you barely idle it up at the throttle it evens out. all motors do it but you dont notice it because the cylinders are combined to one exhaust.

I have duals and it's normal. It almost seems as if one cylinder is pushing the other along. I can't recall now but I remember reading in the Briggs manual to run the engine and 2000 rpm and remove a spark plug wire and note the rpm drop. It should be the same for both cylinders.

thank yall for the help.
