well...this 'll be the probably ups & downs of my first project ever...i have a 32 cc craftman retired from a weedeater...it has a centrifugal automatic clutch and it has not run for a while...just purchased a carb kit (metering needle, diafragm, gaskets & a couple of screws). I have good spark and compression so I hope the carb will get it to run again. After lots of reading I decided on an over rear wheel setup, belt driven system, similar to a GEBE. That's the plan...still a lot of details to work out. My intention 'll be to use an smaller bicycle wheel without spokes in place of the plastic ring of the GEBE system but I'm not sure how to attached to the rear wheel yet. I know they sale the plastic ring that snaps in place but I'll try first to do it all with the used stuff I have at hand. If any of you have done it and can advise it will be much appreciated. I'll be using a Mongoose Mountain Bike that was picked up from "garbage bulk day" and have seen better days. I'll be attaching some pictures as the project develops and I'm looking forward to any sugestion you may have. Thanks to all of you that have been so encouraging!!
