On my motor listed above, I was setting the link and sync - no major issue.
But, when I was manually turning the flywheel with a timing light on the plug wire #1, the trigger would send an EXTRA spark to cylinder #1 about an inch before the belt alignment mark - I'm guessing that this would be somewhere around 40-60 degrees btdc. The trigger would send a normal spark at 0-2 degrees btdc as it should. This only occurs on cylinder #1 - none of the other plugs seem to be affected. It is a real strong and loud contact too - more so than the regular trigger marks or contacts.
I doubt this is normal, unless it's for very low rpms to help start the motor - which I doubt very much.
Any clue as to what would cause this? And, what to fix or check?
The motor runs fine in and out of the water, but if #1 is getting an extra spark (which does not appear to happen at decent rpms, and I have a ruff low idle in gear in the water, but who knows) I don't want to blow my #1 piston.
I'm thinking that I need to look at the cdi, or the rotor.
Please let me know what you think....
Here is a video of the motor in the water - notice how it's rough between the hole shots.
