Father reported his 2 stoke backpack blower wouldn't accelerate. I didn't test it I just took his word and quickly checked the exhaust screen--it was not plugged and I didn't put it back in. The air filter was filthy. I just Installed new carb, fuel lines, fuel filter, air filter, plug. (yes, a dirt cheap kit off ebay--they work) I demonstrated it ran like a champ. Next day he says it isn't fixed--same problem. I try adjust the carb but can't get it to accelerate either--idles great--not exactly bogging when throttling up just runs bad. I have an induction tach I put onto it and at idle it shows 3,200 rpm give or take 60 or so. When throttled up it fluctuates widely from like 1,400 to 4,500. The tach usually shows leaf blowers idling at 3,000 ish and full throttle at 7,000 ish. Given the tach is actually just ounting ignition impulses could the coil be bad and only causing a problem when throttled up??? You can't get dirt cheap coils. :( Thanks.

But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
