Kawasaki fr691v help

My thought is that there may be a hole in the top of the air filter due to whatever has been spilled on it. Through the hole, it ingested a bunch of dust, which I doubt came from sitting all winter. Likely another all-too-common case of not treating a lawnmower with any respect. People need to start treating their lawnmowers like they do their cars or trucks. Or, expect it to break down.

Thanks for you reply that was no help at all. Yes that dust is from over the winter being stored in a barn with chickens and goats 10 foot away. Not everyone lives in a subdivision and parks theirs in a climate controlled garage.

The dust on the outside is from where it's just been sitting out in the barn over the winter. The engine is clean and the filter box is clean. I just haven't pressure washed the outside of the mower yet this season because when I first started up this happened. But yes, the smoke is whitish.

H'm, the first startup after winter storage and whitish smoke. Do you by chance add (actually over add) Sea Foam to the gas as a stabilizer? If so, drain the gas and try with clean fresh gas.

Have you checked the gap on your Cylinder lash valves? The only time I had a lot of smoke coming out of the muffler is when my FR691v lash valves where not gaped properly. That is between .004 - .006. I did mine at .005 and the engine stopped smoking. This is recomended to be done every 300 hiurs..

Good morning, I have a Toro ZTR with the Kawasaki fr691v. I went to crank it the other day and it was bellowing white smoke out of the muffler. Oil was not overfilled. After researching it appears as though the head gasket was blown. Also, with it running and smoking when I open the oil field oil was spraying out. I disassembled the engine found very little Carbon on the piston and valves. The cylinders look great. I changed out the head gaskets, cleaned everything and reassembled, set the spacing on the valves, and cView attachment 73312hanged the oil filter and filled to the correct level. It fired right up however is still smoking like a freight train. Any ideas?

Didn't run a compression test did ya. Not the "does it have compression" test but a differential test to determine where the oil is coming from. Could be a broken ring, worn cylinder, both, valve seals, etc.

I suggest:
1) Clean the engine and the entire machine.
2) Change ALL the filters.
3) Drain the tank and add fresh fuel with some Sea Foam.

See how it works after doing the 3 steps and report back on the results……. Next step would be a "Sea Foam engine soak" to free up rings, valves, etc.
