cherry red muffler
Got an email from a buddy in RI who is doing some "head scratching" over a Kawasaki, 18 HP, 2 cylinder PROPANE on a big buffer. Muffler runs cherry red. He's changed both coils and plugs, checked compression, air cleaner was changed recently. From the little I know, sounds like the classic "running on one cylinder" and unburned gas getting dumped into exhaust. However, propane isn't something I'm familiar with. He routinely works on these and when he saw it, he immediately changed the coils and plugs as that is the "classic" fix. Bad coil out of the box? He still has an inductive timing light and I suggested he try that to verify both plugs are firing.
Sorry, no model numbers.
