.28 Engine Gone Wrong

[nitroboi]

hi people I've got a .28 nitro engine and have tuned so it can ideil and run for about 5 seconds. I've give it gas runs like a bullet but then i let the throttle go and keeps going for like three to four seconds and then dies whats wrong don't know but hopefully u do:bow::bow:

Kind of sounds like the carb or the throttle linkage is sticking. with the motor off use the TX to go full throttle and then release and see what its doing. Let us know what you find

The manual states the engine is broken in after something like 6 tanks. This is B.S. Leave that engine slightly rich and run it easy for at least a gallon. It is not going to tune properly until the pinch relaxes.
