Troy-Bilt Horse riding lawn mower, Kohler engine
Hello All,
I picked up an abandon Troy-Bilt Horse riding lawn mower with a Kohler Courage sv720 v-twin 23 hp engine.
In an effort to get it running I did a cylinder leak down test, adjusted the valves, replaced one ignition module,
changed the oil and oil filter, fresh air cleaner, fresh fuel filter . . . when I got it started I let it run for about 10 min.
while checking the alternator output . . . all looks / sounds good.
My question is how much oil reaches the top end of the engine in the rocker arm / valve spring area under the valve covers, the number 2 cylinder seems to be a whole lot drier then the number 1 cylinder.
. . . there is some evidence of oil on that side, but a whole lot drier than the other side . . .
Also, no accumulation of oil on the lower portion of the head/ valve cover area in the low spot below the rocker arms,
seems to me that the low area of the cylinder head would accumulate about a cup of oil before it was high/deep enough to flow back to the sump. What am I missing?
Any information will be helpful . . .
Thanks,
Doug Lee
