Bought boat with motor out, installed new head gaskets, intake gaskets, pressure tested exhaust with air. All good. Got boat running, ran ok...impeller in leg was not working replaced...
Boat ran. Installed thermostat as I forgot to when replacing manifold gaskets...Had someone looking to buy and was running boat on a garden hose at idle. 4.3 was reaching operating temp and it quit running...hard to sell if not running.
Since then I have changed the coil wire as coil wire as it was arcing, tried adjusting the timing. Stick my finger is #1 spark plug hole, turn over boat and it seems like I get 2 compressions...
I am thinking the valves may be too tight. Compression tested #1 cylinder and it's a 90 psi.
I have read recently not to spin the pushrod but to try to pull them up and down to eliminate lash. And 3/4 turn after lash is gone. Pretty sure I went to 1-1/2 turns when reassembled. Thoughts?
