Have Zenoah G3800 c/saw, 4 yrs old, has not done a lot of work. Started fine a week ago, and was fully cleaned up following use. Will not now start.Good compression and spark. When saw is tilted on its side for fuel filling, fuel leaks from fuel delivery line tank grommet. Fuel line seems to be OK, but grommet is not a tight fit into tank. Sucking through fuel delivery line/filter assembly can be done, with a little resistance.
As carby is a Walbro diaphragm type, what amount of suction effort should be required to provide required fuel flow?
Could it be that the carby diaphragm has failed?
I am at a loss as to explain what has occurred, as it has happened so suddenly.
All helpful suggestions welcome.
(Relevant fuel delivery line part numbers are 22,23,24 on manufacturer's parts list.
Thanks.
