[3757chevy]

Today I modified a part to make my compression tester work for my truck. I posted this in tool threads as well......I bought a compression tester to use on my '35 Chevy with a '67 Chevy 250cid inline 6cyl engine. The engine uses long reach spark plugs but the threads in the head start aways down in the head.[as seen in picture #2 in fitting #3] The fittings that came with it would not work for my engine so I bought a package of spark plug non-foulers and modified one to work . I thought I would share my fix in case anyone else ever has this issue.
