Low compression

[Bob Underwood]

Checked the compression by the wet test 75-50-50-65. Am going to put in rings, rod and main bearings, new intake valves

Should anyone have a secret to putting back the valve spring retainer keepers it would be appreciated.
Thanks Bob

Bob, first, cover all the openings for oil return with a rag to prevent losing a retainer down one of them. Then place a dab of grease on the inside of each keeper and it will stick in place while you are installing them.

Use a small magnet to handle them... like the pencil shaped pocket ones.

Wheel bearing grease and a long thin flat bladed screwdriver.

Usually the exhaust valves goes first.

Bob, I don't know haow experienced you are, so I may be statinf the obvious, but the new vlaves will need to be lapped in, and I would lap the old ones too. As Eugene stated, unless they were out of adjsutment the exhaust valves usually fail before the intakes, due to the heat. Also, the rings will help, but unless you have leaky valves, which you would have needed the difference between a dry test followed by a wet one, to tell, rings will not be enough probably.

Is the engine smokey running? I would run seafoam through i t and let kroil inserted through the plug holes sit in it a day or two or at least overnight in an attempt to get the carbon out of the ring lands and see if you can improve things with out a big deal. I constantly remind my self, KISS (keep it simple stupid) It is amazing how much good cleaning things up does. Many cubs have set for a while and all kinds of crud and crrrosion screws things up.
If this doen't help then it is time for the big deals. When you get to rings people sometimes miss that the ring lands have worn and are wider than the new rings. There are shims for that but with my CRS I can't remember the name for them. Of course you could change the pistons too. This takes it out of the simple catagory.

Thanks for all the help. Agree with John exhaust should have been first to go, I think they were set to close. Case mechanic said .015 book says .013. Reason for going all the way pistons have some movement I think rings will take up the slack. I had it running did not notice any blue smoke. The valves need attention and should it smoke I would be wasting a head gasket, was told it was over hauled 10 years ago. I used to help my Dad work on cars they were over head valves where you could get to things. Bob
