Did some more digging today.
Boomer, on the Green site is telling me that the bypass starts opening at 20 psi so I guess these don't build much more pressure than that. Before he posted that info I decided to pull the oil bypass spring and check it. It is in spec, length wise at 1". I pulled another spring from a used block I have and it was also 1". I then figured I would stretch it a little and see what happens. I stretched it to about 1.2" and reinstalled it. Here is how it ran after that. https://www.youtube.com/watch?v=F7UE...ature=youtu.be That looks a lot better. I ran it for maybe 5 minutes and look what happens to my pressure. https://www.youtube.com/watch?v=qGrKzZlg_Ws I'm not sure if the spring got weakened and I didn't pull it to check because I have a new spring coming from Onan this week. It looks like to me that the pump can't pump enough oil at slow idle or I have an issue with an internal leak or a clearance is too large somewhere but I would think you could hear that and would it loose that much pressure? Did the 30W oil get warm and caused the pressure to drop off? Anyone have any thoughts on this issue????? I know, I know, I shoulda repowered but that's not going to happen.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
