When i joined I ask about a manual clutch, and did not get any good feed back. lol now I notice I have an old Consew sewing machine clutch here. I started looking at it today and I am thingking I could adapt this to work on my bike motor project. anybody know what i am talking about? ever seen the older kind that is not machined to the motor, I think I could cut the extra metal off and would weight less than a pound or so. I notice some of the China motor kit's come with a handle bar clutch lever to control a clutch of some kind, should I just buy one of the chiengines to more understand how this is done, I still plan to use a weedwacker or blower motor. but I could use help with the many part's I am having trouble finding and or adapting. is this an adviseable move if I have the spare money? Thanks in advanced Jim S...
