Love 'em ideas...
I just tried the hill again, blasting the throttle every couple seconds... no backfires, just a hiccup once or twice. Once in a while I could find a middle ground where I was applying just enough throttle to keep the motor humming without it hiccuping.
This is my first moped. I was under the impression you could do full throttle down a hill (I'd love to see that speedo needle buried).
Aside from plug chops, how do you guys know when you have the mixture screw just right on the A55 delorto carbs?
