  • / March 28th 2018 first start up 10547 and 10590 compression test
Sharpened each blade with a bastard file and stone, filled tanks, checked compression. 10547 2002 (6.5 dura force)with short block installed 5 years ago 115 psi. 10590 1991 M-series 115 psi. I do not use any stabil or ethanol fuel, just straight 87 with tanks 1/2 full stored in a garage. Each started on 2 pulls. I have had the 10590 for 3 seasons. I have cleaned the exhaust port and cleaned carb-air filter installed a e3 plug is all I have done to motor. I do use a high quality oil (blue marble) as well as adding Energy Release to the oil. I am not here to pimp the ER. I really do not like telling anyone I use as it comes off as belonging to a cult. I have seen positive results in my 01 chevy and all of the snowmobiles that I have owned for 15 years. The compression of the 10590 was right at 105 from day one. I have checked it every season including the start of last season (105). I added ER the beginning of 2017 season (1oz per qt). The same time I installed an hour meter. I have 8 hours on the 10590. I was really surprised to see the compression come up 10 psi. I also have ER in the mix used in the 10547 and the compression has not changed a bit. When I have inspected the cylinders of the snowmobile engines I noticed a few brown or bronze spots along the cylinder wall. This is the ER bonding itself to hot spots. It must help create a tighter fit and possibly loosen up the rings. I will put this link in only to help answer your question (what is energy release?) http://www.energyrelease.com/

Hi Lewis,

Interesting info on the ER.

I used to sharpen my lawnmower blades with a bastard file also. Always thought the somewhat serrated edge left by the course file (like a steak knife) actually cut the grass better than sharpening with a bench grinder.

Regards

Jeff

I used to use a round stone with a drill, I usually ended up taking off too much on one side over time. Now I use a bastard file and stone to hone the edge. I can maintain the factory edge doing it this way. I use both mowers so they each get 1/2 use. I will sharpen again in sept.
