i just purchased a this motor earlier today for 30 bucks , the guy said he couldnt pull the cord nemore so i took the recoil of to get to the wheel and it would spin about 300 degrees or like 12- 11 (clockwise) on a clock any ideas he said it was just working the other day and he was using it and running fine then it just stopped? i need help asap before i just start ripping this thing apart

Pull the spark plugs and stick a long screw driver in each spark plug hole and make sure both pistons go completely from top to bottom and then back to the top.

Spark , fuel, compression??? You need to check these things out in order to determine what is wrong with it.

Pull the flywheel off and make sure that it is not hitting a loose coil. If that doesn't work, then take off the lower end to make sure nothing is messed up down there that is hanging up the engine. If that doesn't work, then something is seriously wrong inside of the motor and you've just made it much easier to throw into the trash by disassembling it. :D:D

What daviet said--check to see if both pistons are moving. Sounds like it tossed a rod (broke a connecting rod)

johnnyrude lower units rarely seize up. But it happens.
Probably seized powerhead.

I think you have to remove the powerhead to remove the lower unit, not sure though.

On another hand, Im trying to assemble one of these engines. If you decided to part it out, let me know.

If the plugs are out and it won't spin all the way it threw a rod, the crank will hit the rod as the piston is stationary.

i can get the flywheel to spin about 300 degrees , when i would to go pull start it i couldnt even pull the string, how hard is it to check and change a rod if it is? i have no reason to check plugs and fuel since i have the plugs out and it wont spin..

As noted - stick a screwdriver in the spark plug hole and spin the flywheel. If one of the pistons isn't moving, that's the culprit.

As for replacement - gonna need a donor motor to get the parts from. IF you're lucky, the crankshaft is okay and the rod broke away from the journal. IF you're VERY lucky, the rod didn't ventilate the crankcase when it broke. So, if you have a usable crankshaft and block/crankcase, then you're halfway there. Now you need to find someone else with the same issue - aided if their motor roached the crankcase and crankshaft, leaving them with one good connecting rod.

Bottom line, you won't know what you've got and what you'll need until you get it all disassembled...

You say you have no reason to remove the plugs. Sort of sounds like you aren't listening to what everybody is telling you, doesn't it?

He said the plugs are removed but the flywheel only spins 300 degrees.

Something in the combustion chamber blocking the piston from coming up?

It could even be a rod

Did you check coils to see if one is loose/sticking out and hitting the flywheel?

Then un-do the screws that hold it down. Phillips head, two go through the coils and two are between the coils and breaker points. You don't have to take them all the way out, they will release after unscrewing them several turns.

EDIT: Those things throw rods because somebody takes them apart and they don't pay attention to the carbon seal that is at the top end of the drive shaft. That seal assembly must be 100% good, and assembled correctly. If not, water gets into the crankcase and you are now seeing the result. Be sure to use a new 303347 o-ring and 303355 gasket.

F R im not trying to remove the coils, i need to get the wheel? that they are on off and the screws i can see holding it down are underneath that wheel? and i cant get to them. what im doing now is taking my broken powerhead out and putting the newer one in and transfering everything over to the new i got the fly wheel off the carb off and cleanned and so on.. the only thing i cant get is the stupid wheel that holds the coils on in that the screws are underneath it theres got to be something im missing.

The screws you can't get to? You're not supposed too.

You've loosened two screws, and the "wheel" won't come off. It's called the "armature plate" I believe.

There are three machine screws that you see on the coil. The two towards the outside of the wheel hold the coil to the wheel. The one's towards the middle you need to take out.

It seems like the first two should have done it, but the other two do double duty.

I hope this was helpful, Make sure that the coils are lined up flush with the flat boss on the wheel. If you loosened the outer two screws on the coil. It might have gotten out of position.
