There are two causes of your problem that I can think of: firstly, it may be that you, even after changing some jets, haven't got the air/fuel mixture right. If i were you, I'd put the standart jets back in, set the needle position to the middle position, and screw the air/fuel mixture screw 2,5 rotations ( 900 degrees) out from fully screwed in. This should return your bike's mixture settings to approximately standart. Then, using this page
determine if you have a rich or a lean mixture, and adjust accordingly. If you have any more questions, or would like me to clarify something, please ask.

    Oh, and secondly, after you cleaned the air filter, there may be an air leak somewhere, which makes your mixture so lean to the point where it won't start. So, just check for air leaks in the air filters joining point to the manifold, on the manifold itself.

Clean the out door coil, take a garden hose to it, and be thorough. A dirty coil can not reject the heat and will shut down. You should clean the indoor coil as well just watch that water stays out of the furnace.

sounds like you still have a dirty carb but.I'd change the plug. clean the air filter. check the fuel screen in the fuel tank, make sure it is fresh fuel, if none of this works I would think your carb is still dirty or out of adjustment.

Edger will not stay running

Cleaning the plug doesnt mean the plug may not be fouling out. It is usually the easiest and cheapest resort,rule it out by installing new one. Take the air filter out while you try to run it also,if it isnt either of those I would look into having the carburetor cleaned and checked.

Lose of power on acceleration like its starving

Sounds like there is a load of dirty fuel in that gas tank. Ran good for a while after changing fuel filter, then began to run poorly again. Remove fuel tank, drain and clean out, replace fuel filter AGAIN. That should cure it. Hope this helps

Under load the engine sputters and backfires.

I had the same problem; The first 2 years the engine ran fine and then the third year it started backfiring, so I put a new carburetor on my engine and the same thing happened. The real problem was the valves needed adjusted. Yes I know, this is very rare, but it did happen. I decided not to try this adjustment myself and opted for a mower shop to do it. It cost about $50.00 and the engine has been fine ever since.
