Compression test ?

whats the best way to perform a compression test ?

With a compresson tester on a warm engine.

Bruno why not just get you a leak down tester and check it that way, that way you check the ring seal, if thats what you are worried about....


Randy

Throttle blades wired open, coil wire disconnected and all plugs removed.
Best to disconnect the wires coming from the box than just pulling the coil wire. I always seem to put my hand on the coil, for some reason! LOL

X1000

bout the only thing a compression gauge is good for is degree'n a Jay Allen camshaft.................right Coug??????

ok then Bruno
#1. take the plugs out
#2. open carb wide open
#3. remove coil wire
#4. crank it over X amount of times, I go 3 to 5 complete rounds
make sure you do it the same to every cylinder but make sure you watch the guage so you can count how many time it pumps and do every one the exact same amount of times.

and that will give you an indication if something is wrong.


but you can get a leak down set up from Snap On or Mac, or Sears

Jon the way I degree Jay Allen Cams are when I get them I remove them and Drop them over a Brick and when they break I deposit both the brick and cam in Dumpster.....

Wish I could have saved the brick, Hate wasting a good brick on a worthless cam but you have to make sacrifices.....

What I did was have someone watch the gauge and tell me when it no longer went up. Then I stopped, plus the carb was closed. I guess I did that wrong but I did it before the teardown and I'm punching it out 30.
