Re: First spark but problems.
It sounds like the slide is in backwards. The cut goes away from the engine, it would be facing the air cleaner. The roller guiding the bottom of the chain should be as close to the large sprocket as it can be. The purpose is to guide the chain on first and then to be the tension-er second. Look at the teeth on the sprocket some of these sprockets have square teeth, if so you will need to make them look good. the sprocket on the other side should be the example of what it should look like. You are going to have fun so keep it up you will get there. Have fun, Dave
