Hi we have a Flymo hover mower with a Suzuki M120X 2 stroke engine. If the air filter is removed it runs fine. Fitted a brand new Suzuki air filter but problem still the same. Having cleaned the plug the engine will start but within 20 seconds it run very rough, blue smoke belches from exhaust and eventually stalls.
Remove plug to find oiled up and very sooty.
Tried different petrol oil mixes as have several 2 stroke machines so know fuel and oil good.
Carburettor float and pin working OK.
Any ideas before we have to take to repairer

:welcome: Welcome to the forum!
I'm going to move your thread over to our repairs section. :smile:
Sounds like it is running very rich, removing the air filter increases air flow and the engine runs better. Has the card been "played" with and possibly is the choke stuck closed? Let us know what you find. Found this and it might help you: http://golftechs.us/Manuals/Suzuki.pdf

Hi Tom, thanks for the link. I am sure it will be very useful..
Unfortunately the choke is fully open after starting and stays fully open. It is exactly the same condition as a stuck choke but not so.
Hi folks. I thought I replied to all. Eventually stripped carb and cleaned, however I noticed a crack in the fuel pipe right on the union, no fuel ever leaked out so may have happened when stripping down. Changed fuel pipe and refitted carb. It starts first pull and runs like a dream.
A BIG thanks to all who helped.

Mike,
Sounds like you fixed what ever was the issue. Glad you let us know it is running better. So many folks ask questions, get answers and we never hear back from them.
