Certainly Alan is absolutely correct in the choice of a top end rebuild , but as a short term improvement at no real cost in time or money the , also the factory way to lessen the same problem , fitting wires in the intake rocker feed passage does offer some improvement , tho small . Til you can properly tackle the problem . While no cure it may be a mild panacea .
Plug fouling occurs mostly in town traffic not on the open road where throttles are higher , vacuum pulling less on the worn inlet guides , and cylinder heat is greater keeping the plugs burning cleaner .
Worth a consideration anyway . Sid .
