C10a Loosing power
I have a 1975 C10a that I put a new plug and points on last year, and it ran great up until a week or so ago. Now it is loosing power super quickly. I'd love some help with why...I'm at best a middling gravely mechanic.
I have replaced the ignition coil, plug, and plug wire, and that hasn't fixed it.
When I pulled the old plug out, it was *super* fouled. This plug was probably 6-8 months old, and I had replaced it because the old one was super fouled. The beast pumps out a lot of smoke when it starts, but when gets up to full power, I can't see anything smoky.
When it gets bogged down (unduly quickly) there's definitely black smoke coming out of the exhaust.
