Ok, I need a little tech assistance. I have an IO-360 with an RV-74 prop and a Jihostroj P-920-028/A governor. I did the first engine run on the weekend and the good news is the engine fired right up and ran like a champ. The bad news is that doing a prop check at 1500 rpm with 70 psi engine oil pressure results in no change in the prop rpm/MAP or oil pressure. After shutting down I disconnected the governor output line that runs up to the front of the engine case and there was no oil in it. The crank does not have a plug in the front. The prop lever cable is attached to the lever on the governor and it does move over its full range of motion. When I pulled the governor off the back of the engine what seemed like about 1/2 a quart of oil ran out. Any ideas on troubleshooting or possible causes would be much appreciated. I'll even report back when I find out the rookie mistake I've undoubtedly made.
Thanks
