For gasoline engines I agree with your line up... especially with the Tecumseh having the most problems...
With Diesel engines, I have to go with Kubota, Wow they build a very dependable engine... :smile:KennyV
I'm partial to Kohlers myself. I do have a Yanmar diesel too (JD 790 Comact Utility)! :smile:
As for least favorite, There's a reason Tecumseh is no longer in business! I do still have a couple of them, 10" tiller & generator. :frown: ~~ grnspot110
don't have a favorite gasser but Yanmar and Kubota are my favorite diesels. russ
I'm getting a lot of insights here. I see a number of affirmations about Kubota. Many friends swear it's a good choice, especially in tropical conditions.
