Pullstart 62,905 #1 Posted May 6, 2019 Ok, here’s a Commando 6 with an H60 that I picked up. For now, my quest is to see if a Kohler carb will run the machine. First things first, drain the nasty fuel out of the system. The linkages on this machine are severely customized, but the Tecky governor at least functions. The choke obviously does not function a complete motion due to the slop in the custom linkages but between the two carbs, I don’t see much difference. Here is some baseline detail of the throttle at idle and wide open, along with choke operation. The exhaust has been modified and bugger welded quite heavily, that’ll change some day too. 3 1 Share this post Link to post Share on other sites
953 nut 55,297 #2 Posted May 6, 2019 Kevin, it looks like you have some P.O. modification to repair, but know you can do it! 1 1 Share this post Link to post Share on other sites
pfrederi 17,741 #3 Posted May 6, 2019 You may not need the cast iron spacer behind the carb. Tech carb bodies are short the throttle butterfly on some sticks out past the carb body. at full throttle 1 Share this post Link to post Share on other sites
Pullstart 62,905 #4 Posted May 6, 2019 There’s an adapter plate of sorts on the Tecky and it appears on the 656 as well.... even though neither engines appear stock. The Tecky carb measures about .808” and the Kohler about .820”. but it fits! I don’t expect this carb to run flawless and will likely get a new eBay carb, but I’d rather tune the Kohler than most others! 2 Share this post Link to post Share on other sites
Pullstart 62,905 #5 Posted May 6, 2019 The throttle linkage is a bit short to idle down and the choke cable will need to be re-routed. 3 Share this post Link to post Share on other sites

Pullstart 62,905 #7 Posted May 7, 2019 So, with some more measurements, the idle setscrew was the limiter, not the governor rod. Backing the screw out all the way, I am pretty much spot on for the rod.... so I’m running with what I’ve got! The choke will be handled via replacement cable most likely. This one appears way too short regardless. 1 Share this post Link to post Share on other sites
bottjernat1 2,190 #8 Posted May 7, 2019 yes i have one on my daughter suped up workhorse 800. it has a 12hp tech on it with a kohler carb. i got tired of messing with the carb every season so i put the kohler on it when i was younger and she has worked every since i was 18 and i am now 38. the old motor is wore out pretty bad but still ticking! Literally!! LOL 4 Share this post Link to post Share on other sites

I just did some quick research on the ariens company didnt realize they have been around since 1933. And they are an american family owned business. pretty cool! 2 1 Share this post Link to post Share on other sites
