1650 smoke from engine after shutdown. need ideas!!
 

im going through a newly acquired 1450 for my friend and i got it running but noticed smoke from under the engine tin after i shut it down. so i removed the engine and all the tin. not oil leaks anywhere except a little from the breather but i think thats kinda normal? cleaned the grass clipping off the flywheel and head and thought problem solved.

put it all back together does the exact same thing. i did notice its charging 17 volts so i unplugged the regulator thinking maybe the stator would get hot from overcharging. ran for a few more minutes hoping the airflow would cool it down. didnt help still smoking in my garage right now! its been like 20 minutes and no change. Comes out behind the carb and mostly the hole in the flywheel cover where the air cleaner hose hooks into.

the smoke smells like hot engine. not electrical or oil smell.

i have no idea what it could be any ideas??

That is a odd problem, maybe someone will chime in that has seen that before.

Out of time? :bigthink:, Been messin' with the points?? :bigeyes:

Incorrect timing might make it run hot.

Hmm....interesting problem, especially if you cleaned it out already and don't see anything. I'd run some Marvel Mystery Oil through the fuel system and see if that helps at all. That is just a quick guess, maybe to free up something that might be obstructed....

I use Kaopectate after I use Marvel Mystery Oil for an obstruction, OH, you are talking about a tractor!! :bigthink:

:bigeyes:

:biggrin2:

Points haven't been messed with but I should check the timing. Doesn't seen to run unusually hot. I'm hoping it could have been residue from the brake parts cleaner but I have my doubts

i think the brake cleaner residue was the culprit. it was smoking the first time i ran it due to the grass clippings inside the tin. i didnt have time to tear it down and didnt want my house to burn down so i sprayed a whole can of non flammable brake parts cleaner on it to put out the "fire". it must have taken a few runs to burn off the residue but now it doesnt smoke any more.

thanks for your help guys!

Good to hear John!:beer2:

Glad it wasn't anything major wrong. :beerchug:

me too. i was afraid i smoked the stator
