So far yes. There are a lot of variations of them. That one will allow you to use it easily and for most spark plugs.

This is the one I got about 10 years ago and paid about 35$ for. It also has a release and will work on two different plug types.

just bought one at Advance for $24.99 came with all the different adapters you'll need them cause you need to use the adapter that is the same length as the plug or your compression readings will be off.

I know how to check the cylinder compression but where do you hook up to check the block compression on a two stroke and what pressure should you look for? ???

a 2 stroke makes same on both sides of the piston if you have a bad crank case you have no compression same as bad head gasket.

I purchased one from Auto Zone for around $25.00 and use it often. I keep a log of the compression of all cyl. and check the compression several times a year. Most engine failure is do to a clogged jet which causes it to burn up the cyl. By checking several times a year if you notice a drop in a cyl you can correct the problem before it does too much damage.

Thanks for all the input guys,
but I missed the e-bay one cause of a business trip.

We have a harbor freight store here in Reading, Pa.
so I will check out the stock.
I get a lot of cheap tools there and if they break so what,
most times I only need stuff for a one time job.
