interesting, thanks.the engine doesn’t seem to circulate water very well. To remedy this I have swapped water lines around and it seems to have helped but still doesn’t seem right.
The water enters at the top of the head and exit out the side of the block. This is the only way I can get water to move thru the engine.
As far as timing and needle settings everything is correct.
For some reason it did burn the electrode off the spark plug the first time I ran the boat assuming because the engine got hot from lack of water running though it.
The spec of electrode that came off did make a small mark on the sleeve.
I realize this this will hurt the performance of the engine but I don’t want to put an new piston and sleeve in the engine tell the water issue is 100 percent fixed.
As far as needle settings, did you experiment with measuring the height of the (needle) screw heads? (mentioned in a previous post?)
