5ive-T 2.0 throttle transition

[Mark Muller]

I'm on my break in tank, motor ran good for a couple minutes & then started bogging ( I think as it fully warmed up ) at transition from low to high speed. 25:1 w/93 octane, 88 F out side. My tuning experience with chainsaws, weed eaters is to rich up the low speed needle to get better response but the instructions that came with it say the opposite. I checked fuel lines, tank vent, even pulled the carb looking for air leaks. removed the bottom of the carb where the fuel enters it & everything clean. Low speed screw is now at 1-1/8 turns out & don't think I should go any leaner. What say the experts?

H1 7/8 L1 3/8 ?? start there and if you need to tune only adjust 1/16 at a time

Thanks, actually it probably didn't have all the air purged from the fuel lines. hit the bulb about 15 times to be sure, started & ran good for a half tank.

Pushing the prime bulb puts fuel pressure in the fuel line ?? (purge) if the bulb is not full while you running its an indicator that there is a leak in the fuel system (lines carb) or too much heat??? keep an eye on it ??
