Hey guys
So I bought a '76 650C last July and have been riding it 4-5 times a week since (Texas winters!). I've done routine maintenance on it (oil, filters, side cover gaskets), some light mod work and cleaned the carbs a couple times. I've been having this weird issue lately where my left cylinder sounds like it's missing, but only when I'm idling and its hot. It pulls through all the gears fine and no sputters all the way through the throttle, never has, only when idling.
I did a compression test, 105 on each side (low but I'm waiting til summer for a complete rebuild). Checked plugs, looked good and changed them anyway, gapped them properly as well. I cleaned and greased my advance, then opened up my points to find this......
Is that a pamco? PO definitely didn't tell me that was installed. I've never taken the time to check the points as it's always run fine until now. If so, that sputter wouldn't be timing, would it?
Any advice appreciated.
