speedo keeps resetting itself changed plug wires moved everything as far away as possible nothing works
im thinking your right it worked back in the day just fine but now local stores don't carry them ebay i guessAfter my first shwinn electronic one became possessed from my CDI it was never the same and only worked intermittantly. I replaced it with a good old fashioned mechanical unit. I'll never go back it's so much easier to read. Cruising at 30 is the middle of the gauge it's great. Give up on Chinese electronics and get a tiawan front wheel mechanical unit for your $20 you will be much happier. I've now topped out around 42 mph but I think it could go faster but I don't want to. Go old school and get a gauge.
beenthere done that solid copper core wire new cover nkg sparkJust use a resister plug and you should be fine.
do you put that over your spark plug?when I was building/running 2smokes, I solved it with this little filter
