Seeking guidance for tuning a CH18S Kohler Command (1995), as replacement for a 16hp Onan (1990). This Kohler doesn't have the torque-grunt of this Onan, but it works, and is my available option. So, how best to tune the Kohler for this application? 1. I believe Onan and Kohler high RPM setting are both 3600? 2. Would it hurt the Kohler to boost that RPM to 3700-3800? Would it really help any? 3. Would it hurt the Hydro Transmission to go over 3600rpm? 4. I guess I could go find a slightly smaller Drive Pulley? And what would then happen to the Trans if I can't get the proper RPMs to the Trans? Now that I've figured out the mounting arrangements I can always swap in a bigger engine should I stumble upon a better option. Given the difficulties of getting the Onan rebuilt now-a-days, I'm looking to go for a more modern engine with easier to find parts/service. And I'm not inclined to do an engine rebuild myself. Thanks, - L.
Before I re-invent the wheel, I'll ask. I'm putting a CH270 Kohler on my 857 to replace the trashed K engine. It appears the throttle cable needs to enter at the right side rear of the engine, instead of at the front on the K. I know there are a multitude of brackets that would make the job relatively simple. BUT where would I find details and where to order them from. If push comes to shove I'll fab something but I have a feeling a "factory" bracket would be a lot less work and need less refining. I know you all like photos so here are a couple. The last one shows how I think the cable will eventually run, maybe? Or will some kind of bell crank be the ticket? Ed
