    Finished up the swap tonight. Drilled some holes in the hood to keep it cool. And notched the side for the oil fill. Gotta clean up the engine to match the rest of the tractor but other than that it's done. It runs beautifully and is so much smoother than the flathead was! I have a total of 38.00 into the swap so I'd say it was worth it! Excited to put it to use.

    I did however, find that the bearing on the double pulley for the deck is shot. I ordered the bearing to replace it today. Anyone ever replace it? It's a weird long bearing that is apparently pressed in? Currently soaking it in PB Blaster waiting for parts.

    Got the bearing out of the double pulley this morning. Lots of heat and a BFH and it finally came out. No way to do it without damaging the lower pulley. Luckily, metal likes to go back to its regular shape. More heat and some bending with pliers and it's back in shape. Hopefully the replacement bearing is here tomorrow. I want to try this beast out!

    Got the pulley back together and the deck back on. Gave it a quick test run and everything works great! Mows better at 3/4 throttle than the flathead ever did.

    I have used this thing a few times and found two issues that will need taken care of.

    1 is the battery is not charging. I have voltage coming from the engine but apparently somehow it's not getting to the battery. I'm still looking into it but I think I'll end up putting a direct line from the engine to the positive side of the battery.

    2 the fuel pump is not getting enough pulse at start up to keep running. I think I'll have to run a new line to the valve cover to get proper pulse to the pump. Once I get it running it's fine.

    Still super happy with the swap. It will chew through a huge pile of leaves without bogging down now.

    Can anyone tell me where this is supposed to go? Its 2 white wires with an eyelet on the end. It was connected to the back of the block with the old engine so that's what I did on the new one. But, I'm not convinced that's where its supposed to go.

    No one? Does anyone have a wire diagram of a NON points 111? The newer model? Or a pic of the back of an engine on a 111?

    A ring terminal like that that doesn’t have heat shrink on it is typically is grounded.

    Do those wires come from the engine or the tractor?

    Boy I feel stupid....you know how many times I looked at that wiring diagram? Too many to admit to not seeing what you just pointed out. Looks like they do indeed go to ground. Thanks for pointing that out!

    I guess I'll have to start looking for other reasons for the no charge issue.
