First, you said you checked the fuel pump.
Then I said Clean the carburetor and gave very detailed instructions.
Then you said you already had.
I also said it could be fuel quality.
I also said:
check the compression. You said you can, but did not provide results.
unit is running too lean..
It is either not getting enough gas or on the flip side, could be getting too much air.
Make sure there are no air leaks anywhere.
Could be a bad gasket, a warped facing somewhere that a gasket normally is enough to help two surfaces meet.
it could mean clogged exhaust ports or bad reed valves that are to close on the power stroke.
Could there be a clog in the muffler or exhaust ports?
Then I said I think you may have to look at the possibility that you missed something in cleaning the carburetor.
Some tiny port or hole that needs to be soaked, drilled out with a tiny stiff wire, or blown out with air.
The I detailed fuel quality problems.
"Also, the gas does not have to be "in the tank" for longer than 30 days. It could have been stored in a Gas can that long and still have gone bad.
I summed up saying.
Head Gasket, Intake gasket, cylinder gasket, fuel filter?
Just keep thinking....
Too much air, not enough gas, lack of compression, wrong mixture, fuel quality...
Check to make sure the spark plug is the right one and is perfect. Must ignite at correct temp.
Then you argued with me on fuel quality and how long gas stays good.
So I provided a third party Write up with links to support my position on fuel instability over 30 days.
The you Stated "told me to do what I already did!!"
Said you missed something when you cleaned the carb.
And, that I said take it to a pro if you can not figure it out.
Well, If you are going to argue with the advice rather than take the advice, then no one is going to be able to help you.
I stand by my answers, and am insulted that you think that all I said was do what you already had done again.
I will revise my statement. If you can not follow the steps that I have given you and take the advice that is being given to you in good faith, then you need to take it to a pro.
I will opt out so that someone else can help you if they think I have missed something.
