70esl75b I'm in need of a schematic for the fuel pump in order to reassemble, have kit and upon disassemble i saw how the plungers work but a small o ring is in question. The diaphragm piece was worn but no holes. Also when removing from engine i left inlet with screen intact, however there wasn't a circular spoke gasket there but this kit has two needed? This is on a 24' pontoon.
the motor starts cold with choke and idle lever up, after warm starts with or without choke sometimes, then idles ok, however putting throttle to half or higher it gets hurky jerky, if i back off to a third it cruises fine. sit for a spell, then start and go she throttles up WOT for 45sec to a minute or so then fades to up/down, up/down like throttle on off until you back off and at one third cruises, will go all day on a third.
I have replaced fuel line, and tanks, ball stays firm. Motor ran good last year, i winterized carbs. has good compression, and i set timing this year advanced 24 degrees suppose to be 27 by the flywheel, but this seems to be what she likes.
thank you all in advance.
