Having a good run yesterday then all of a sudden it stalled it is a 26cc cy engine went to try to strat it back up white smoke came out of exhaust every time i pulled the starter so slowly released the fuel cap and the fuel was bubbling with a lot of pressure behind it left it to cool down then it fired up again nothing wrong what could this be ?

white smoke........blown turbo mate :lol::lol:
Never heard that 1 before. Maybe you need a new plug?? What colour is your old plug? This will give a good indication of tuning and whether it is running rich or lean.

The fuel cap breather is not breathing mate......pressurising the tank...

Sort of like a lawnmower petrol tin when you shake the fark out of it to mix the oil....the can pumps up like a balloon....undo the cap and it goes PFFFFFT.....

Same thing...

This pressure has to go somewhere....and what better place for it to go than through all of those little jetty wetties in the carb........flooding the engine.........the fuel evaporates.....leaving behind lots of oil......hence the smoke!!!!

His old plug would be as black as the ace of spades........and wet as a shag:laugh:

i agree, cap vent is miffed, get it figured out. the tank pressure was pushing more fuel thru the carb than the motor could use, so it essentially flooded itself out.

fix the cap vent and this issue will go away.

Don't know if you can use it, but check out the Full Force kit on Ebay, reference 370360502014
I've fitted an earlier version on my FG MT and no problems.

if you have any nitro stuff kicking around, the nipples that go on the pipes to feed pressure to the tank work good. screw one into the gas cap and run some line out to the back of the rc. no more pressure and cheap fix
