Why wont ANY of the adapters in my compression test kit thread into the head of my cherokee? Its a 94 cylinder head and its a harbor freight compression tester. The thread if the plug and my adapter match but it won't thread in. am I missing some kind of trick here ?

 

Do you have a long reach adaptor on the end of hose fitting, or are you trying to thread the stubby fitting in...if so it won't work. You need the long reach adaptor.

 

He needs the WunHungLo extension.

 

This is start I have

 

Pic is so tiny I can't tell if you have the proper fitting.

 

When to the HF website and if this is your kit there's no long reach fitting in there. Get your money back.
