1.8 Cvh keeps stalling..
today i was trying to double check my prop was balanced but every time i tried to get it started the engine kept on stalling.
I havnt run the engine for some time now but cant see any reason why it just cuts off. Most of the time it doesnt start unless i put a tiny bit of fuel down the carb, at which point it will start, but after about 5-10 sec the engine will just stall. If i start revving it abit it will run for about 20-30 sec, but again it still stalls after that. Im not sure what it could be, but i thought it would be a fueling problem, so i ran it from a bottle to the fuel line and fuel flow seemed fine. it does seem to idle quite high and still is running rich from what i can see? any suggestions? i have tried playing with the idle speed and air/fuel screws on the carb but not to much success, i could be being a complete idiot with them though.. Thanks!

Air leak somewhere perhaps?

That was my second thought after fuel which geeman seems to have eliminated.

Air leak was my first thought.

not sure why its stalling but I had a similar problem with my CVH engine running a fast tickover, took me ages to work out what was causing it
It was traced to the automatic choke stepper rotor thats between where the throttle cable linkage at the carb & the carb body, As I,m not using the auto choke its not connected but the stepper rotor was sitting at the higher revs position as if it was "thinking" it was a cold engine, I think there are 3 steps on the rotor so I just "adjusted" ( fixed in 1 position ) at the lower setting & hey bingo it solved the high tickover problem Might be a similar problem on your engine cheers andy |

The should sit at 2000rpm for initial cold idle.
