wallfish 17,023 #3 Posted October 20 I don't know much about those engines but we did get one of those big 2 strokes fired up and running at the big WH show using a regular old 4 stroke #26 carb. It bolted right on. Anyone that was there that evening, no matter where they were, had to hear that open pipe 2 stroke screaming away. That thing was LOUD 1 Share this post Link to post Share on other sites

That thing was LOUD What was the oil/gas ratio - I remember back when Dad ran all vintage Lawn boys if you bought lawn boy oil it was ( I think ) an 8oz can of oil in a gallon of gas - in a pinch you could use regular motor oil - they smoked like freight trains - your story reminded me of those days was sitting here thinking surprised that old Kohler 2 stroke didn't fog the place too ....if mom had wash hanging out and we'd start mowing and trimming he'd hear it ...lol Share this post Link to post Share on other sites
wallfish 17,023 #5 Posted October 20 The OM Gary posted has it. 20:1 Modern oil is so much better than the old stuff too. I have a bunch of little 2 stroke engines from the 60s (70 or so) that call for 16:1 mix with 30w oil but we all run them at 32:1 with modern 2 stroke oil. We siphoned gas from @stevebo's snowmobile to run it. Personally I'd run it at 32:1 with a good quality 2 stroke oil but that's me. Do Not use outboard oil, it's different compared to air cooled oil.

wallfish 17,023 #8 Posted October 20 Love that sound I don't see any rpm reduction so that tractor must fly with that many RPMs to the trans. Any problems with stalling the engine when taking off? Share this post Link to post Share on other sites
