As the title states last night It ran solid in practice. Then when heat time came around I got 4 or 5 good laps in then it's started to burble and sputter so I pulled off not wanting to hurt anything. Engine normally dies when choke is applied, this time I couldn't get it to die..it was idleing high and choke did pretty much nothing..
First thought was clogged jet. So I removed the idle screw, popped out the jet and cleaned liberally with brake clean. And reinstalled. Fired it and seemed to run ok on the stand with a normal idle and seem to rev ok..
Went out for feature and made one lap and it did the same thing again..
Am I hunting the wrong problem?
What am I missing..
Engine has about 45 laps since fresh this spring and was keeping up with the front in the heat till it started acting up
plug is 3910x(plug is also 45 laps old)
