Hi guys, I'm new here, and hate to start out with a problem, but I have a decent sized one.

I bought a Tmaxx 3.3 used, when I bought it, the seller started it and ran it, it started easily, and ran great, so I think I have a problem that I created. When it was real cold, and I wanted to run it, so I tried to get it running, but it wouldn't start. It stopped turning, and I saw a puff of smoke coming from the starter motor. I replaced the starter motor today, went to start it, and it still won't turn. I can feel the electric charge hit the starter motor (the small nudge if you touch the outside of the starter) though, but still won't turn. Any ideas?? It wasn't fun pulling the motor all out, so I'm not looking forward to doing it again if I don't have to. Thanks in advance, I'm really looking forward to getting this running, so I can play!!
 
when its cold it always helps to heat the head and block of the engine with a hair dryer. sounds like you may have flooded the engine as well. take the glow plug out and see if the ez start will turn the engine over. if it will, heat the head and block with a hair dryer, put the plug back in and try again.

also, getting a seperate glow ignitor helps tremendously vs using the blue wire
 
It is possible that ur starter wand is bad. I got an old maxx from a dude and kinda same thing. I used my wand from my truck and it fired right up. Then used that wand again and nothin.
 
If you're using the same wand, try a different one. It could have been more than the motor that fried.
 
Turn the engine by rotating the flywheel. It could be stuck. After a few rotations, leave the piston at BDC and loosen the glow plug slightly. Hit the starter, and if it spins and starts, tighten the plug.
 
I can manually spin the flywheel, and I pulled the glow plug and and still nothing from the starter motor. I'll pick up another wand in the next few days and see if a new wand changes anything
 
When you hit the button, do both green lights glow?
You might also try reversing the wires. You might have them reversed.
If you had the one way bearing out, that might be in there backwards.

I put my one way bearing in backwards once, and it just spun on the shaft, no binding or anything.
 
No, I didn't remove the one way from the housing, and both the lights on the wand light up. I ordered another wand, as to be sure that isn't the problem--should get it in a day or so. I was also careful to make sure the red wire goes into the post marked with the red on the engine. I will reverse the wires tomorrow to see if the result changes. Thanks again for the suggestions--I'm trying them all, just no luck yet. Please keep 'em coming!!
 
Before spending money on a new wand, remove the starter motor but leave it connected to the wires.
Hit the starter button. If the motor spins, you have a problem in the starter gear box. Maybe a broken tooth jammed in the gear.
 
You could always go to a pullstart and glow stick. Get rid of that bulky weight of a starting system and start going fast !
 
I reversed the starter wires and the starter spins, but, of course won't turn the engine--so this tells me something is wrong in the gearbox. Once I get it apart, is it easy to tell where there is binding?? When I had it apart the first time, there was a white substance all over the gears that looked like lithium grease, and I assumed it was supposed to be there. I'm going to take it all back apart this afternoon again to see if I can tell visually where the binding is. thanks for the help so far guys.
 
Ok, I pulled the engine back out, seperated the starter and starter gearbox, and everything is ok there, but as soon as I re-attach the gearbox to the engine, stops spinning again. I try to manually spin the shaft into the engine, and it doesn't spin. Does that mean my engine is bad, or is there a way to get that spinning again??
 
No, the flywheel wouldn't turn. So I pulled the glowplug, sprayed wd40 down the hole, and heated the engine with a blowdryer. Then I took channel-locks, and freed it up by spinning the flywheel witht them. then I re-attached the starter assenbly and it all turns over, but then I had a battery issue--so it's been charging all night, and will hopefully be running today!!
 
And now it runs!!!! Man is that thing fast!! Thank you for the help guys
