Topic: compression

[cyclezirk]

I have read all the posts (threads).  Please correct me if I am wrong...but is this how to do a compression test:
1. Warm engine
2. Choke off
3. Throttle wide
4. Plugs out
5. Screw in tester and push the starter
6. Read the guage
7. Move to the next one

That's the way I do it.

You push the starter until the needle of the gauge is not moving any further.
Obviously you want to have a good charged batterie for the test, to have enough juice for the four testing sessions 

On thing to add though: Kill switch is switched to OFF while testing

Thank you.  I appreciate your help.

One more thing... turn the fuel tap off too, saves flooding the motor.

I'd even drain the carb bowls, no need to suck any fuel in that won't get burned-off.
