Compression Tester fix (my way)
 

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 fitting #3 in picture #2] 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.

Nice work on the fittings,,,,'

I would have used the straight probe with the rubber nozzle on the end....

Too each there own.

I wanted to do a leak down test as well. The result was 113# on one of the cylinders 133# on another and the other 4 were 126# average. None of them leaked down at all.
