‘74 GT550 no spark from left plug

Post by pgb123 »

Can’t kick over. I used an inline spark tester and the left plug isn’t sparking. Tried two new plugs. If I connect the inline tester to the left plug and the middle cap, I get spark. Is this necessarily the coil? Could it be the wiring, the cap, the points? Where should I begin?

Thanks in advance!

Btw, carbs have been cleaned multiple times. New pilots. New battery fully charged. New gas. Filters in place. This is a new issue.

Could be a faulty plug cap. Just connect the ht lead directly to the plug and see if it fires.
Think of how stupid the average person is, then realise that half of them are more stupid than that.
