CC3184, CH18 backfired, lost all oil

So all winter now to start my Cub I've had to pour some gas into the carb.. not a lot.. maybe a shot glass worth. Anyway the other day I might have poured a smidge more than that because when I went to start it up.. the engine caught for like 2 second then backfired.

Afterwards it refused to idle without 3/4 choke. I've since discovered when that happens its either very lean or very rich. Also since then, and removing both heads last night, I noticed the entire 'passenger' side is coated in oil. Anyone whose worked on a twin cylinder Kohler knows the fan in those things will MOVE SOME AIR. So what I suspect happened is somehow oil leaked and was blown into a mist coating that side of the frame, steering linkages, muffler, etc.

Now I suspected something sinister like a broken connecting rod or a hole in the case but nope.. none of that. Cylinders look nice and clean.. pistons and valves move like they should. And in removing that sides head I mean yeah it was nasty.. but the gasket showed no obvious signs of being breached.

The plan is to reassemble with all new gaskets, make sure the intake bolts are torqued (when I unbolted it they all seemed looser than what they should have been) and both intake gaskets had what appeared to be a plastic like see-through film that looked to have been part of the gasket as one point but since some had dislodged into the fuel/air stream. Anyway reassemble with all new gaskets, properly torque and throw a carb kit in there while it's all open.

Any advice would be greatly appreciated.

The backfire may have blown the intake gaskets out for good. I think your plan is sound in trying to reseal everything and rebuilding the carb.

Probably because, for many/most 2 cylinder engines, the intake and exhaust system connects to both cylinders, and you have to unbolt them from both cylinders to remove the part, so you should replace the gasket on both cylinders, whereas you can remove the cylinder heads independently of one another.

Re: CC3184, CH18 backfired, lost all oil

Actually I now remember that the intake gaskets I replaced a couple years back had adhesive on one side. I questioned it at the time but it sure did make installation a breeze. I wonder if that adhesive 'film' is what I saw.. this time if the gaskets are the same I'll try to adhere them to the intake side rather than the head side. Oh and tighten the bolts more
