Ok, hopefully some of you remember me.
1978 galaxie 22xl 260 merc chevy crate motor with 100hrs.
Only pull 3000 rpms. Backfires as well at wot
Have read the sticky.
Replaced the ignition parts, had all timing dwell advance set by dealer
Replaced fuel filter at carb, and water seperating unit as well
Bottom of boat is clean.
You had recommended checking anti siphon valves. Well maybe this is it.
Have two rectangular steel tanks each side. On one side, the check ball had yellowjacket bee parts in it, and I blew them out.
On the other side though, there was rubber stuff in this one, but it broke off in the brass fitting that is between the tank and the check valve. Also, the one on this side, the ball is noticeably bigger than the other one.
Also, on this side, I noticed that there was some what appeared to be gas just slightly leaking around the base of the brass fitting where it screws in to the tank. Is there some sort of sealant you use on the fitting when you screw it in to the tank, and when you screw the anti siphon valve in to the brass fitting?
Can this be part of my problem? Also, I noticed that the fuel sending wires are zip tied to the fuel line. Is this correct?
I am also putting new plug wires on and using seperators as it seems some of the wires kind of criss cross each other, that does not seem right.
What about the fuel pump? Could this be an issue? Accelerator pump in the carb? Seems like she comes out of the hole ok, but just flattens out on top.
Any help will be appreciated!
