Your top plug hole has been repaired with a threaded insert. That's why its so big. The insert came out with the plug instead of staying in the head. Probably need to soak the plug in some penetrating oil to free it, then secure it in the head with threadlocker. I think this engine is going to run!
Cool shirt! This one seems like it has been around the block. Seems like you have gotten some good insight from the other comments. Look forward to the update after the parts come in!
Thread insert came out with top plug ,remove from old plug and reinstall with locktight, do not use starting fluid on 2 strokes it washes the cylenders out just mix up some fuel and put in a squirt bottle,rope the flywheel after you clean and set the points .thats a great engine there.
I soaked the plug and thread insert in PBlaster and loosened things up, I then soaked the coil in acetone and dried the heck out of it with and air compressor, then I carefully coated every millimeter of the outside of the thread insert with permatex red and screwed it back in… it has been curing for over a week and seems like that thread insert (coil) is bonded solid but I think I got the plug stuck in there too somehow and haven’t had the guts to really crank on the plug to back it out, I might just leave it for now until I get a chance to run it and let it heat up
Thank you for the heads up. That would be easy to check and since I have that new hydraulic puller. I ordered the parts already so I will do my best to remember to pull the flywheel in Part 8b.
Starter fluid in 2 stroke is just fine but don't over do it. Make sure there is fuel in the bowl of the carb. Once it fires it will drink some of the good stuff and be just fine. Working on old junk like this I wouldnt worry about it at all. Maybe if yoy had a nice old dirt bike you just restored dont hit it with hot stsrt but other than that no big deal.
lol OLD junk is right, when I was buying these I was guessing most were from the 80s, not the 60s, amazing how well the old stuff is holding up given 50+ years in most cases
Dont spray starter fluid in a 2 stroke,old and crusty or not,it strips any and all lubrication off the needle bearings and other innards of the motor. 2 stroke mixture in a squirt bottle works fine.
OK. I think you have sheared off the key on the crankshaft that locates the flywheel. Probably it sheared the first time it backfired, or it may already have been sheared. Pull the flywheel and check. Evinrudes need to be torqued carefully for the flywheel bolt.
@@BooBoo-zi2zw The backfire tells you that the spark plug fired at the wrong time in the rotation. Common problem for those. The key is cheap. On that model, the correct torque is 40-45 lb.-ft, if I remember correctly. The flywheel is held in place by the torqued-down bolt or nut. The key is designed to shear to prevent damage. It is only for proper location. It's not strong enough to prevent misalighnment.
keep it up I have a feeling your channel is going to be very poular
thank you!!!

ok, will stick to my premix squirt bottle, thanks for the advice

checking soon, once parts arrive
cool
That could be how the starter pawl got broken.
@@dondondon5695 Yes, it could.
