1 cyliners not working

[748cc]

Did you say that valve clearances were checked/adjusted recently? You may have a tight intake valve thats dumping fuel all the time, plus ruining your combustion chaber vacuum. It'd only be a matter of time before any spark plug gives up to those conditions.

One other suggestion: swap the plug wires for 1&4.

If #1 still fouls out, you will KNOW it's not electrical.

already tries this steve and problem moves with the lead/plug cap but it has brand new coils/leads/caps because it was doing the same thing before and the only thing I could surmise was a faulty coil/lead/plug cap

Are you saying that if you swap wires, then #4 will foul out?

If that is true, you don't have very much to inspect there.
1. wire
2. cap



By the way, new parts can be faulty, and there is always the possibility that they are assembled just a little bit "not quite right".
