not to jump around but on that original motor posted about, I neglected to mention that the coil that is barely firing, I spliced a new connector onto it. I have seen in the past that with good coils, splicing basically makes the coil next to useless. Has anyone else noticed this?
However I also tried taking the bare wire lead from the coil and connecting it directly to the magneto lead (#1), coil still fired the same way. Switched magneto leads to the bottom coil and plenty of voltage coming from both magneto leads and firing strong on coil #2. So it’s coil #1 that is weak.
With the 2nd motor, the customer had the motor run totally fine and start right up easily on 3 occasions in a row, but at WOT after 2-3 mins, the motor dies out like it ran out of fuel and he can’t get it to restart no matter how many times he tries to pull it over. He lets it sit for 45 mins (or overnight), and it starts right back up like nothing ever happened. Fuel pump is working fine.
He said that at the end of last season he noticed a few times toward the end where it would not hit WOT or only do so for a few seconds then get stuck at mid-range. Carburetor is freshly rebuilt, float is set correctly. He has been running it this year and experiencing this, and I’m hesitant to say it is a plug issue because they are brand new plugs, but then again, the motor can’t be running anywhere near operating temperature in 40° water. Pumps water like a fire hose.
