Getting a 92 Cub 1861 with engine problem. Shuts off when it warms up and won't restart. Got a 87 Cub 1720. Will that engine fit the 92?

This was bought new and trouble since day one. Dealer screwed around till warranty was out and since then closed down. It runs until it warms up and shuts off. Can't start it again till it cools down. We were thinking the heads are warped. I was just wanting to know if a 14hp from a 87 cub 1720 work in that.

Just because it's old, doesn't mean it's obsolete!

Sounds like a coil is getting hot and shutting down.. Do you have spark right after it shuts down on you?

Engine won't run, so just swap it out..... I never understood that line of thinkng.~Jonathan

My memory isn't the best, but I thought it was visited before...
They can't all be turn key.
Make the best of each and every day.

You are correct. I wasn't paying attention to the model number. 1861 is a Mag 18. And it is also a magneto motor, but not a dual mag. It's a single mag, dual output (wasted spark) and could very well be the issue. AND, it could still have a fuel solenoid. Wasn't standard, but we don't know what's been done over the years.
I change my position: check the Mag.~Jonathan
