I have a problem with my 84, 12-A. Since I took it out of winter storage it ran great for 15 miles or so. The next time I started it, it smelled hot. In checking, I found the RB header glowing red hot. It idles slightly rough about 1600 RPM.
I checked for obvious vacuum leaks or choke problems, but found nothing.
Now the header will start to glow within a couple of minutes of idling. I can pull any 2 plugs off and it will still keep running.
The only mods are the RB header & I run prenix 1-oz./gal. The aux. oil pump is blocked off. It's been running great like this for 2 years. Milage is 65000.
Anyone have any ideas about what's going on?
