Hello, I have a turnigy 52cc engine with about 30 flights on it in my laser. I would start the engine with my glove on and flip it about 5 times with the choke on, it would kick, then choke off , one or two more flips and it starts.runs smooth, plenty of power.
Now when I start the engine it kicks back real bad , but after the kick back when I flip it again it starts up and runs perfect. I didn't change anything, same plug, never touched the carb settings, same timing. Same gas, same prop. Any ideas what it could be?
