I have been putting together a 29 inch cruiser for a long time. This has been a very frustrating build and I have lost interest several times. I started this build using a 49 cc 4 stroke motor and got it running but decided to go with a 66 cc 2 stroke and that is what I am working with now. The motor is installed and about ready to go. When I mounted the ignition block the insides of the spark plug cap fell out on the floor. My attempts to reassemble it failed so I bought a new ignition block and installed it today. I put it on the bike and checked it for spark and it did work. When I pulled the spark plug of of the cap the insides fell out and onto the floor. I am willing to buy a new ignition/coil but really want a better quality unit than the ones that seem to fall apart. Who sells a good product or how can I fix the caps I already have?
