We have an 8183T with the ONAN ENGINE after running good for thirty years it is now giving up the ghost.  We replaced the oil pump (after looking all over for a replacement) then this spring it ran for about an hour and started smoking badly.  I parked it and the next day tried to start it but there doesn't seem to be any spark.  Could it be a bad coil and if so are we finished as parts don't seem to be available for the ONAN.

Which Onan is this? There are still parts available to rebuild most Onan's. Just not cheap!

Welcome to the forum!


Don't give up on the old Onan yet.  Gravely always picked a good brand for their machines. 


I imagine, unless you have already tested by isolating the coil from the ground wire, you have a tractor problem: there's always a good chance for a bad safety switch of some sort.

There are lots of reasons for lost spark, and even if you have a bad module, there are some aftermarket/retrofit ideas.
A model of onan will help the guru's
Good luck
