| hello, i have a xcell gasser with g23, total of about 7 tanks ran, all hovering(admitted still scared), my last hover flight ended with the engine cutting out but did not die, above mid throttle, bought her down, started it again fine, mid throttle about 3 feet after take off, engine sputtered, again brought it down, checked plug it looked dark, very light oil on it, so i thought maybe the plug fouled, so bought the ngk bmr7a plug, gap at .022, started the engine fine, attempt to lift off, again the engine sputtered, but did not die still idling fine, checked plug it was dark again, using 1 1/8(high), 1 3/8(low), did make minute adjustment on the high and low, but still sputterdright after lift off, the only thing that i did before this happen was i refueled the gas container with 89 octane(1 gallon) and 64:1(2oz) amsoil mix, i did have about 1 tankful left on the old gas left in the container than added the new gas with oil mix, i have ruled that the plug, high and low settings would not affect trying to mid throttle, could the coil be going bad, took the air cleane off and ran it without with no difference,i did take the carb(walbro 176a) apart to clean, blew the ports with air compressor, the metal screen did have a thin film of light green slime, i put the carb back, one thing i did notice was the fuel inlet, when i blew into it was obstructed, so i took the carb apart again, blew thru the inlet, air came out fine, till i put the gasket and plate, then it was onbstructed again, any help or suggestion or is that normal. |
