Hi folks.....I've moved from repairing lawnmowers to building motorized bicycles as they are way more fun. I hope to pick up a few tips here and would be glad to share my limited knowledge of gas engines.http://motorbicycling.com/images/smilies/shft.gifhttp://motorbicycling.com/images/icons/icon14.gif

Welcome to the forum. I think you will have a blast building a motorized bike with your experience.

Now all you need to do is hook up some lawnmowers to a bike and make crop circles while riding around...

Thanks guys.....I do have a question and it's regarding the use of a piston stop to torque the magneto nut as I'm concerned about damaging the piston. Has anyone had any experience using these.....if so was it good or bad. I used to use the rope method on 4-cycle engines but it catches in the ports of a 2-cycle engine so I am going to try bringing the piston up to within an inch of TDC before feeding the rope in. Any other ideas for torquing the nut effectively?

Try a penny pinched between the primary and secondary gears on the right side of the engine. The penny won't damage the gears. Also be careful tightening that nut. The threads are only 10mm and not the hardest metal. Don't over do it. I wouldn't exceed about 150 to 160 inch pounds.

<Thanks for the tip 2door Iwill try it next time...pennies are scarce up here in Canada. The rope worked great but I only left 1/2 inch making sure piston was on the way up. I'll remember that about the threads though.
