			Wanted to decarb, so I came up with this contraption to run some seafoam enriched fuel through it (a little heavy on oil, I know).  Seemed to work pretty good... the fuel disappeared faster than I would like to have seen, but it ran smooth.  I'll check the compression tonight and report back.

			The compression is between 72 and 77 on all 6 cylinders. Is this OK?  
		
		
		
		
		
		
			
		
		
		
		
		
			NYMack... how about that T/T? I have the electric on the throttle and under the cowling, but missing the T/T entire assembly, including any wiring harness that may be needed. I can drive down to pick it up. Last edited by awthacker; 12-02-2010 at 11:50 AM.  |

 wow it's runs um suprise that's super low compression. i don't know if i'd waste money with a v6 tilt trim unit for it when it has low compression. you will need a V6 tilt trim unit. not one off the V4's unless you have a press and lots of time plus extra money to convert the mounts and bushings to the V6 style. if i remember correct NYMack's is a V4 unit.

			that's a 20" motor. compression should be 115 min to 135 max on each cylinder.
