Re: Yanmar loses RPM in gear
yanmar 1gm,motored up river for 1hr all good,following weekend would not start.
have had injector cleaned,fitted new head casket as oil was grey,now changed oil/filter.fuel filter primary and secondary changed.water pump hoses clamps all changed.motor will not start when does need full throttle and then it slow builds revs,knock throttle back and it stops.cleaned elbow.
is this a fuel pump problem?or rings gone on piston?
thank you paul
