ET: Engine (Twin) 1954 Black Shadow Oil Fouling on front Cylinder only, any checks?

John, to confirm that your guides are letting in oil try this. Find a long descending hill and cruise down it, then close the throttle for a few seconds. This creates a vacuum in the inlet tract that will suck oil into the cylinders if the guide is worn. Open the throttle again and look for a temporary plume of smoke from the exhaust. If there is one your guides are likely worn and need replacing.

The other way to stop the plug from fouling is to up the fuel and air intake! for as long as it takes!

Thank you Jc,. I have a good balance meter so I will go through all the checks and balance the slides as the seller recommends. I'll keep you informed.
