1989 johnson 110 problems

hey new to the forum and have a few questions that hopefully someone can help me out with. first i have a 1989 johnson tracker 110. the motor was just rebuilt last month but am still having troubles with it. took it out and it was running fine then the motor would bog down the tach would drop to zero and it would kill out. talked to my mechanic and he said that with the tach dropping like that the voltage regulator was probably bad. i changed the voltage regulator and the motor fired right up. took it out the next weekend and after running about 3/4 speed it started to bog down again and kill out but the tach never dropped to zero like before. tried to get it running but could not had to be towed in 2 trips in a row. now the starter seems to be getting stuck when you try to crank it. fooled with it a little but the body of the starter gets extremely hot after just trying to crank it just once. now the gear on top of the starter sticks up in the flywheel and will not drop back down. should i get a new starter or get the old one rebuilt. also with it sticking up on the flywheel will this cause the motor not to start because i cannot get the motor to start at all any help would be greatly appreciated because the guy that rebuilt it will now not return my calls as i have tried to get in touch with him several times in the last few days. thanks

It sounds like your battery is undercharged. Check the voltage across it, it should be 12.65 volts. If it doesnt have enough juice to spin the starter, the starter wont be able to spin the flywheel since the starter shaft has a groove in it that wraps around the shaft in a spiral manner. Protrusions inside the bendix ride in this groove. When the starter spins, the rotational force of the shaft causes the bendix to rise up that spriral. Therefore the bendix locks in one direction so when it engages the flywheel, the flywheel turns. When the engine fires, the flywheel causes the bendix to spin faster than the starter so if you are a little late letting go of the key the bendix free-wheels to avoid damage. Normally however, just letting go of the key stops the starter and the bendix drops down the shaft. Check the shaft and groove for any burrs and file them smooth. Clean the shaft and groove and then assemble the bendix. A light lub is all that's needed on the shaft.

Also if you find that the battery is not charging, thus causing your undercharged battery, you need to troubleshoot your charging system. Since you already changed the regulator, check all your connections and wiring, make those connections shine. Test the rectifier and the stator, these will be covered in your manual.
