motor issues, carbs dirty maybe?

[2182]

just got back from water test. idled around to purge any old gas, then got up on plane for a few miles, nothing wrong, no beeping, no warning lights, no godawful bucking. i wound up burning about 4 gallons of fresh ethanol gas w/ no issues at all. im going to try and get it pumped tomorrow. may not be the only issue, but its a good start. i dont think i have more than 20 gallons in the tank. thanks for all the good info guys, ill keep you posted.
