Sorry to pester but I think I now have good reason to post this.
1977 470 serial 477XXX
Bought it - ran fine.
Brought home - Ran fine
Took to boat yard - starter shorted. Replaced starter - broke solenoid - replaced solenoid - no start.
Got spark, but carb is throwing fuel out of the top and the inlet is wet but it does not soak the plugs too bad.
I have a notion that there are valves stuck causing pressure in the inlet.
Could it be anything else ? what can I try ?
Changed conderser, plugs and roter too just in case.
Also rebuilt carb with sierra kit.
Still no joy.
Please advise as it was 30 C here today and no water fun.
Thanks in advance.
