I brought the motor into a highly respected mechanic to do the following work:
Link/Sync the new cables that I had previously installed.
Troubleshoot the ignition system for an intermittent problem that produces the following symptom:
1.) Motor will not start when cold - no spark. After all of the tinkering in the world, and waiting about 30 to 45 mins most of the time it will crank and run fine until the next time it happens, sometimes a month goes by and its fine. when it does happen, it always happens in the morning at 4:00am when I am trying to go fishing. - Checked the following: remove red plug, disconnect entire ignition stop circuit. Problem persists.
Troubleshoot the ignition system for a persistent problem that produces the following symptoms:
2.) Motor seems to run sluggishly, where as a few years ago it was very fast and snappy. I have lost weight since so its not that. (haha)
3.) Motor sometimes stalls when you put it in gear without adding throttle immediately.
The motor is actually an '83. The motor mechanic says that the spark is great on the top cyl, then gets incrementally weaker for the 2nd and 3rd. The compression is 120 PSI exactly on each cyl, and he says its a good engine mechanically. He said that he could not get it to start, and he gave up on it telling me to pick it up with a recommendation for another mechanic. Fair enough, he didn't charge me. But when I towed it home, I put to muffs on, and it cranked right up. It actually cranked up, and immediately started to run up to a high RPM condition. I shut it off just as fast to ensure my motor did not blow up.
Upon inspecting the motor, the "arm" (green arrow) that controls the ignition timing advance, that is connected to the throttle lever with a spring return, was being held all the way forward when it was supposed to be in the start condition (blue arrow). No wonder the thing was taking off like a rocket! I drilled and tapped a hole in the back of that arm (red arrow), so that i could confirm that would bring the timing advance back into reality and the motor could then idle. It did.
So, now I have a new question raised:
4.) Am I missing a part? how would this timing advance by all the way forward like this?
5.) Is the part that the yellow arrow is pointing to supposed to be green?
Any help to get this beauty back to pushing my boat would be greatly appreciated.
