It's the seat switch. It thinks no-one is on the seat.

there is no seat switch im guessing they took it out a long time ago

Ok then, the wiring that went to the seat switch has a problem. Look where they bypassed it if they did, and you'll probably find the problem.

thanks cheese

Lol thanks for your help. after looking over the wiring studying the elec diagram testing it all reconnecting the seat switch nothing,just a joke when my father asked we what that little stem off the gas tank was and i said its to blow in, well i did and apperently there is a censer for the float and it was stuck blowing twice freed it up ans ran all week just perfect ty for your help and some things are just so easy you over look them.

Glad you got it running, however, there is no sensor in the fuel tank... the hose is a vent. I think you have an intermittent problem and it's coincidence that it worked after blowing air into the tank vent.

no but

no but if the valve i blew in was clogged it would have created a vaccum and it wouldnt have got gas.
