If I'm not mistaken your 34 gauge was for a dip system where it never say 30 pounds and the gauge only went to 30 pounds. Your 261 should be carrying 20-30 even at idle. Could your gauge be damaged from the 261"s higher presure readings? My 261"has 40# at 50-55 mph after warm up and as high as 70-80 when cold.I think I would try a higher reading gauge on it before I started tearing into the engine. That just my opinion. I OL REDNECK
