Rancher delema.
I've been trying to figure this out but this damn honda is so differnt that the kawi motors I usually work on. Heres the deal.
I have a rancher 400AT that was running perfectly fine all day except when I got stuck it was smokeing a little blue, got home shut off went out but when I tryed to start it back up to put it in the garage it refuses to start. sounds like the timeing chain is skipping. air filter box has almost 2 inches of oil in it and smoke comes from it when you try to start. So I got into the engine expecting to find a timeing chain but I find pushrods instead. now I have absoloutly no idea whats wrong. And no it's not going back to the dealer. last visit was for a broken wire that took them over a month to find.

with all the oil yo might have a pluged vent hose. something to check. and as for it not starting check plug and then compression. i have the same quad and i've has it puf smoke also. but it always started beck up.
i would check the vent tubes make sure none of them are cloged. good luck.

the 400 and 350 ranchers are overhead valve type, not overhead cam. This reduces overall engine height making the machine have better center of gravity, etc...
the first thing to do would be check compression. Check in a manual for compression specs, but it should hit about 75% of the normal compression on the first hit, then build to spec after about 4 hits of the needle. If you have low compression, you might have some valve issues or rings that are toast. I hightly doubt the timing chain went, it's a short chain and it's down behind the rear engine case, and you'd probably have to remove the engine to get at it.
Since you have oil and smoking issues, perhaps the rings are bad, and while you do a compression test, you could check for bad rings by first doing a compression test with the engine as it sits now, then put about a teaspoon of engine oil down the spark plug hole and check again, if the resuslts improve significantly, then the rings are not sealing well. If it's still out of specs, then you probably have valve issues.
