Reply To: bottom cylinder fouling Big Twin 25hp

[The red boat]

I have been out of town and unable to work on this motor but I plan to do the following this weekend:
1. check crankcase drain
2. check coils with ohmeter
3. check continuity of plug wires. Likely will replace with new wires I have on-hand.
4. check all wiring under the flywheel; solder and re-connect
5. install new spark plugs
6. I have spare Atom modules – I might swap out the one for the lower cylinder with a new one just to be safe
7. verify ignition-throttle synchro
8. remove sintered element in carb fuel bow (I have installed an inline plastic replaceable fuel filter and can’t tell if the bowl filter is clear or not).
9. examine high and low speed needles.

any other thoughts on this list or the order?
