Smoking honda gx110 qxc on lawnmower - Honda 8 HP Engine

Hi Duane:
I'd be thinking that it's possible that the alignment key on the flywheel has sheared. That will throw the timing out and it can't run.
Fix is pretty straightforward.
Disconnect and remove pieces until you have the flywheel exposed. Loosen the nut. Lift on the flywheel and smack down on the nut with a plastic mallett to loosen the flywheel. Then remove the nut and flywheel. Replace the key (get replacement ant any lawnmower or chainsaw service shop)
Put it back together and it should run just fine.
Cheers.

Hello,
I think that will find that the wire strainer has become blocked in your engine breather system. Unfortunately the engine breather for your engine is located under the flywheel, the flywheel will have to be removed with a puller as this is a taper fit on the engine crankshaft and usually a very tight fit ( especially if it has never been removed before ), once removed you will find a small cover held on with two 6mm bolts, remove the cover and you will see a wire stainer, wash this out, and if possible blow it through with compressed air until you can see through the wire strainer when you hold it up to the light, refit all parts and hopefully you will have many more years service from your lawnmower, I write this as I have a garden machinery repair business in Chedzoy, Somerset, England and have had a very similar problem with a customers lawnmower, best of luck and happy mowing.

usually large clouds of smoke are from having too much oil in the crankcase, or tipping the mower so that oil runs into the cylinder. Check the level of oil, and make sure it's not overfilled.

Honda manufactures all their own products in their own factories including the carburetor

white smoke means that there is water in the fuel air mixture during combustion. a bluish white smoke means oil is being burned during combustion. take another look and make sure which one it is. since all mowers ive seen are air cooled the only way water can be getting in the fuel air mixture is through the gas cap. check your gas tank and gas can for water. may be best to empty both and start over with fresh fuel
