It seems I am destined to have no luck trying gassers. First it was my ignition interference problems, now I lost my CMPro Mustang when the engine stopped during a flight.
I found that the plastic carb fuel pump connection at the base of the engine cylinder had softened with the heat & fell off. I am surprised that the manufacturers fit a plastic nipple in an area that gets hot. The engine was not too lean, if anything it was a little rich, as I was running it in. I now have the engine running again by fitting a piece of Tygon over the remaining brass stub & securing it with tie wire.
Has anyone else had this problem.
