There are many posts on the this site for flywheel removal.I believe it is a model 92 twin cylinder that you have.Coil failure is common.

The flywheel is tapered, back the nut off until flush with the crank, put a block and pry bar so you can pry against the flywheel, hit the crank with a hammer, it should pop off. Did you try grounding one wire and checking for spark on the other, the same spark has to go through both plugs, if weak it won't jump at all.

You have start with first cleaning the points real good. Make them look like new. Then pull a piece of clean paper threw them and gap them to .020. Yes the coils are an issue with these engines but I usually start with the points and possibly a condenser. Sometimes you get lucky. And again you wind up getting a $150.00 coil. Good luck.

Use regular point file or finger nail file the o0ne with the abrasive on both sides. Then use a fine emery cloth to finish with. Use the paper to clean any fine particles or oily film off the points

Use caution when hitting the end of the crank. The crankshafts on these are very brittle and will snap easily if hit too hard.

Once I get wheel off I can go from there just didn't know if there was a trick to removing these specific flywheels. It's rather just locked on tight or I'm missing something lol thanks for the help

Per above the flywheel should pop off when crank end with nut on is struct with mallet (wood plastic prefable). As mentioned the crankshaft on the treaded end is very brittle. There should be some slight side to side play in the crank shaft. Pull the flywheel toward you when you strike the end.
that gives the crankshaft some room to move and break free of the flywheel. Use sharp taps. May be able to use a brass dead weight mallet might help but be careful and use sharp taps. May be some rust on the interface between shaft and flywheel which will make it stick some. Hope this helps.

Kevin

DON'T pry on the flywheel! Stand the engine on its side, flywheel up. Place a couple pieces of 2x4, about a foot long on end, under the rim as close to 180 degrees apart as possible. Loosen the nut until flush with the end of the crank, and either hit with a heavy plastic mallet or place a piece of scrap brass on top of the nut and rap with a hammer. DO NOT hit the nut with a steel hammer! You will either deform or bust the crank! The flywheel should pop loose. Look at the backing plate on the inside of the engine. There should be info there. It will say: 72-D, 72 DA or WICO. The D and DA are Eissman mags, they are the ones known for bad coils. By all means, clean the points, and if no spark, try replacing the condenser first. Set plugs at .025, points at .020 MAKE SURE that BOTH plugs are grounded when turning the engine over. Trying to run or quit the engine by removing a high tension lead is a sure way to kill the coil. DO NOT remove a plug wire while the engine is running!
