My engine came with the MIL that I will install in the existing choke cable hole. I have the engine setting in the frame using a 1864 mounting plate and have the clamping diodes and a electric fuel pump so I should be able to start it up to check oil pressure etc. If it checks out ok I can notify the seller and then I will finish tearing the tractor down so I can paint the frame. I just wanted to be sure the engine is ok as it was a warranty job and he repaired it but never started it.

Where is the best place to buy the Kohler EFI engines? Been thinking about taking the 18hp one in my 1872 & put it in my 682, & put a 23 EFI back in.

I bought my ECH680 from Opeengines.com
Great people to work with.

I got mine through SEW. It was a warehouse left over deal. They seem to pop up every once in a while.

Mine came from a Craiglist ad. A small dealer bought two of these engines as warranty take outs. They had been damaged by someone overtightening drive belts on a wood chipper and burning out the PTO end main bearing. Engine had 7 hr's running time before it went down. He replaced the crankshaft and closure plate. Before I found it I checked and SEW had some EFI take outs for sale.

Finally got some time to work on the 1872 EFI project. I mounted the JD triple hyd valve so I could check for clearance to the fuel tank and also installed the drive shaft so I can get the electric fuel pump mounted to the rear of the firewall under the tank and not have it interfere with the drive shaft. Looks like it will all clear ok. I think I will put a guard under the pump just in case the driveshaft would lose a rag joint. I also decided to remove the Hydrostat pump to see if I can fix the input shaft leak. If I can I will repair the damaged axle housings by tig welding the broken bolt boss area. If needed I can use my mill to face them off. This will allow me to keep the existing rear end and not have to swap a bunch of parts with my spare cyclops rear. Tomorrow I hope to get the fuel system finished up and then run the wiring needed to run the computer for the EFI. I hope to get it running by the weekend. If it all checks out I will then install the 3 point hitch from my other 1872 and get the rear hyd cylinder mounted up. Since it keeps raining and I cannot farm I might as well work on this project. I will post some progress pictures tomorrow.

Well we got all of our spring work finished and I had a chance to work on the 1872 rebuild. I installed the engine so I could test fire it to check it out. It started up on the second turn and sat there and idled perfectly. it carries 50 lbs oil pressure and sounds great. It is very quiet so it will be a good mowing tractor. I mounted the EFI computer and the associated fuses and relay to the firewall and wired it enough to start it. Made a bracket for the electric fuel pump on the firewall under the tank and then added a return line to the tank. My next project is to remove the rear end and see if I can save it. If the input shaft on the hydro is not scored or damaged I will repair the hydro with new seals and a input bearing and see if I can tig weld the damaged rear axle housing. I would rather repair what I have than swap a bunch of parts to make the Cyclops rear I have work in the super. Here are some progress pictures.
Enjoy.

Left side engine with fuel filter. The filter is from Kohler and is rated for EFI fuel pressure. I plan on building a mounting bracket for it on the fuel tank mount strap.

Great job! Thanks for the update pics.

It's gonna be awesome!!:beerchug:

Thanks guys. If it all works out the way I vision it, it should be a really great running/driving grass killer when done. Today I hope to get the rear end removed and tore down to see if I can save it.
