did you set the float height correctly? It still might be flooding some also.

That sounds like it is running too lean. You may need some carb adjustments to account for your altitude.

Hello,
The problem with ethanol gas is that the alcohol eats rubber. The rubber in this case is the fuel lines and the rubber O-Ring located on the carburator bowl. The bowl itself collects junk in the gas and the O-Ring degrades and lets air in /therefore less fuel gets to the engine!
Yo need to take off the carb bowl and clean it and also inspect and possibly replace the O-Ring if it has any cracks in it at all! It would also be a good thing to clean the tip of the needle valve while in there.
Good Luck

I had a similar problem on one of my bikes. Turned out a "Test Port" had rattled loose between the carb and the intake. I threaded a screw in the hole to prevent the leak and problem was resolved.

Maybe it isn't the filter. Have you cleaned your gas tank, you may have junk in it. What about your exhaust, have you cleaned that. It sounds like the caburetor. Are you putting fresh gas in the tank? Are you putting K & N oil on the filter. Try another filter if you think that is the problem. Try using Seafoam in the gas tank, can get at O Riellys. Could be spark plug. To be honest it sounds like all the things mentioned above need to be cleaned

Could be a problem with a bad float that is overloading the engine with fuel. Does it take a little bit to "clear its throat" once you are on flat ground again?
