I have the 9 hp model with the 064 pump. Brand new. I follow direction and close the inlet valve and let it run for 30 minutes to warm up the oil. Upon opening the valve, the vacuum spikes to 27 but slowly drops over the next hour or so to almost 0.
What’s up ? Do I need to run this thing full throttle to keep the oil warm and providing vacuum.? Admittedly I run it at about 1/2 throttle. Nothing in the manual saying it has to be run wide open. Called my dealer and waiting for a return call. Anyone with experience with these. I have used my delaval 76 for years and never had this issue. The oil for the CDL unit is mighty thin #22 I believe.
I have my old reliable 76 cranking away until this gets resolved
Thanks
