Hey there. Can anyone help please my Yam stalls at idle. With any revs she runs but as soon as no revs she clunks out like in the video. I have replaced the fuel primer bulb as it appears to go soft. If I keep pumping the engine keeps running. I have no mechanical knowledge so please help in simple terms ,????

Note in the vid it still stalled whilst pumping this time.

Does it start up without problems??
When was the last time the carburetors were cleaned.
If it was the fuel pump, priming the engine would not let it stall.
Also, check the fuel line, primer bulb, fuel water seperator for air leaks.
Reads like the low idle jet is clogged and/or the carburators are not synchronized.
This is not a task for the untrained.
