Guys I have the strangest problem with my M11. You can start it up and it will run for 30 seconds then die. It takes me a bit, but I can get it re primed and started then it runs fine! It seems I am getting air in the fuel lines somehow.
thanks

That is the most common cause of the problem, particularly if you have the Winn system.
Start by checking fuel filters, as that is a high percent source of air getting into the fuel system.

If you have the clear prefilter one of the o-rings is sucking air.
I got in and started looking at the filters. I have the clear prefilter and a bag hanging down with a hose in it :o
The bag is to collect water.

If you have the WINN air/water purge system the inlet/outlet plastic becomes compressed by the sealing "O" rings so that air gets sucked in.
At the top of the see through container is a thumb bolt. Remove the thumb bolt and lift off the inlet fuel hose/adaptor. Then pull up on container and it will come out. Watch carefully for the "O" rings, two on top and two on bottom. The top and bottom "O" rings are the seal sings. The other two "O" rings are spacers to keep see through container from moving up and down. Look carefully at the inlet and outlet and if it is like mine, the diameter where the sealing "O" rings are will be noticeably smaller. You can replace bowl if you can find one or use "seal all" which is fuel proof. I build short copper tubes which I forced into the inlet and outlet which removed the taper and allowed the "O" rings to seal.
Guys thanks for all your help. Barry that pic looks just like mine, thanks....I found 2 problems first the o-ring on top looked bad and second one was a nice pin hole in the fuelline from the filter to the engine!!!! :-[..I am getting ready to take it off and have a new one made......
