Help plz! Depending on how old it is at least 50:1 but some of the older ones may have been 25:1 First be sure you have a healthy spark. That usually takes 2 people if you don't have a spark tester. If it is sparking you can try just filling it up and giving it a yank. If you are not sure you are getting gas out of the carb, squirt some premix in the throat, open the throttle all the way and yank it. You will start out too rich but after a few pulls the mix will be OK enough to pop. If it runs a few seconds and stops, suspect a carb problem or a fuel delivery problem. They need three things to run... fuel, air, and spark. Greg's method will get you started. Don't forget compression ;-) You actually don't need much of that. I had a friend growing up that had a neighbor with a "collection" of those old single cylinder engines that fired once every 4-6 revolutions. They have almost no compression, and run just fine, sort-of. Similar to this: http://prestonservices.co.uk/item/horizontal-single-cylinder-workshop-engine/ It was pretty cool to go over on a weekend and see him fire one up. |
