...as in crud.
Unwanted deposits of sludge and carbon. Caked up and built up in places it really shouldn't be.
20 years of garbage in the engine. BUT, it's starting to burn off- went for my longest ride yet today- (about 30 miles. Fun
)
But now I need to adjust the valves again...
Big thumbs up to vroom1776 and his how-to-adjust-your-valves thread. It was a big help the first time.
Planning on doing a complete rebuild this January (when it finally gets cool down here in 'lanta) Ought to be fun.
