RE: Saito 180 with perry pump
low speed is stock and just about flush with the arm.. newer engine. The High speed is the 5 turns out per manual for breaking in... I have tried going in and farther out on the high speed, with no diffrence in the outcome. Full throttle = dead engine after a short run up.. Mid range is also good. Just dies out when full throttle is applied and it acts like it runs the line and pump out of fuel...
