Title: 1963 Bridgestone Homer 50CC Ignition Coil
Post by: mobilecycleworks on January 25, 2023, 12:58:00 PM
Hello, I'm having trouble getting spark on a 1963 Homer 50CC.

So far I've tried:
-Checked points (work)
-Replaced condenser
-Shipped the entire ignition assembly to Rick's Electric and they indicated the coils tested good, they believed we needed a condenser which we they could not test
-Tried 3 different condensers with the same results with each

Looking to purchase an ignition coil. Any leads on where to purchase / additional insights on this issue would be greatly appreciated!

Is your an electric start ?. I believe only those models use a coil. Kickstart rely on the magneto located beneath the flywheel. For kickstart models - beneath the flywheel you'll have (1) light winding coil and (1) magneto. For electric start you have (1) light wound coil, (1) ignition winding coil, then a stand alone ignition coil mounted on the frame.   

Check the spark plug cap for corrosion. Based on age these can be a problem delivery spark to the plug.
Have you tried bypassing the ignition switch to see if the switch is interrupting the power from the magneto or coil ?. Could very well be a wiring issue.
Check all grounds (engine) or coil (if equipped) for solid grounding ?.
If you have an electric start model then the coil could very well be the problem. This assumes the flywheel coils or magneto are good.
 
As for parts - Have you tried calling Richards ?. Ebay is another source. I own a Homer and have purchased several Homer parts on Ebay. Parts are general not too difficult to locate.
