Would that indicate a seized piston or something like that? I am not very familiar with 2 strokes.
1st, if you plan on rebuilding this motor and want to learn how to you own maintenance, then you really need to get a good service manual. They have the specifications on the motor and have good detail instructions on how to repair and maintain the motor.
2nd, when you get your motor you will need to remove the lower unit/gear case from the upper exhaust housing. By doing this, you can determine if the head is seized up for what ever reason or if the gear case if frozen up.
- when you remove the lower unit and the motor is able to turn over then the gear case is frozen preventing the drive shaft from turning and thus preventing the power head from turning.
- when you remove the lower unit and the motor is unable to turn over then the power head is locked up or turning very stiffly. This could be from severe coking, overheating situation, broken rod, damage piston/rings, rusting in the cylinder from water intrusion or damage crankshaft ...who knows.
- There is a possibility of both the power head is frozen and the gear case is frozen from damage...again who knows this a new to you motor and you know nothing of its history...other than what the seller is supplying.
(I'm going to back track a little....when you get your motor, try this 1st). Remove both spark plugs and spray in or pour in each hole a mixture ( 1/2 TWC-3 2cycle oil and 1/2 seafoam ) Put the spark plugs back in hand tight snug. Let the motor sit face down (prop up the motor and protect the motor when you do this) with the spark plugs pointing to the ceiling a day or 2 day and then try to turn the power head. To turn the power head (Return the motor to up right position on boat or stand and remove the spark plugs) use the starter rope or manually turn the flywheel by hand. If it is still sluggish or still won't budge then repeat the steps above. Do this for about a week....hopefully if the power head is frozen this might free it up.
If not then go to 2nd step listed above by removing the lower unit.
After you do the above...please update us. (Hopefully you might luck out)
