Just got this motor going after sitting for several years after doing lots of reading on this site as I am a newbie to boat motors I have learned that I should replace the coils on this motor. I put a new carb kit in it as it was full of old gas. I had it running briefly and it seams to die out after a bit it is very hard to start as well. I have read about a inspection plate but my motor does not have this if I take the pull starter of I see A round ring and a nut after taking those off I still cant see in there so I have tried to pull top off with a gear puller and it is very hard to come off am I missing something I thread the three holes with 3.5" long 1/4" bolts and gear puller but it wont budge and I do not want to break it. If the motor runs can the coils still be cracked ??? Or could they be cracked and the points are worn I think that they are the original 63' parts in there, can I use heat to try to get it off???
