well I have several questions here as I am confused, which is easy to do.
I bought this 918 Argo/Allis with a CH18S v twin Kohler in it. when I got it they did tell me it might need rebuilt as it would start smoking after it ran for a few minutes. Well I played with it briefly this summer, tractor sat for a few months I went an turned the key and it fired off. After a 10 min or so it smoked and then bogged the motor down and had to shut it down. I took the air cleaner off and noticed the crank case hose ( I believe ) was dumping oil straight into the card. So I just parked and planned a winter rebuild. Went and moved the tractor to the front of the shop, tractor smoked some during the move but no oil dumping into the card. well I was getting ready to start taking it apart but had to wait now for the motor to cool off a bit. I wait a couple of minutes and touched the one head, (cold) could leave my finger on it forever. other side I still can't touch. so I check the plug wire to see it was firing, started motor no fire to that plug. pulled the plug out looks brand new, not even a dirt mark on this plug (will add picture later).
So here are the few questions I have:
1) If this 2 cylinder is only firing on one side, could the smoke be coming from the raw fuel entering into exhaust and than burning in exhaust?
2) what are the correct plugs for the CH18S?
3) if this right side (when sitting on tractor) is not firing could that cause crank case pressure to be forced in the card thru that hose?
4) I have no current to the plug wire where it would hook onto the spark plug, where or what to look to try to fix.
thanks in advance
