Recently repowered Gravely ZT2044 with Kohler disCourage SV 710 engine and have run it two times for a total of 3hrs. It has been parked up for a week and would not start today. Checked for fuel, found fuel present. Checked for spark, had spark. Checked compression and found approx. 30 psi. The previous engine suddenly developed no compression on one cylinder. I believe this engine has a compression release that may be the cause of this sudden loss of compression. Is this a known problem? Anyone have information or suggestions?

Was engine brand new ? If so take to Kohler shop for repair (don't do anything yourself as it might void warranty)
If not new engine let us know and we will go from there.

It is a new engine Mike, and clearly warrantee work. Being a long time motor head my curiosity causes me to think what might be the cause. Will be taking it to Kohler service shop for work, hoping for at lest a 6 hr. run the next time.

I just thought of something, when you get it back keep close eye on air filter, it's a very small filter on Courage v-twins.
A lot of new engines don't have foam pre cleaner, if yours doesn't you should get one, here in Oklahoma it tends to get very dusty and I wash pre cleaner after every mow. Let it dry and oil with any cheap motor oil, that will help keep engine cleaner.
By washing mine every time the main filter looks as good as when I put it in at first of mowing season.

My recollection is that the compression showed 30 psi on one cylinder and 00 psi on the other, and that I could not achieve those results consistently. It took repeated crankings to see the 30 psi on that cylinder as mostly the results were 0 psi on both. The 30 psi reading was seemingly a random occurrence. Could not establish a pattern.
I have always run these engines with pre filter sleeve, and note that this new one had no pre filter fitted.
