[TR] TR4A - Compression Check Numbers

[diggle at clear.net.nz (diggle at clear.net.nz)]

Those compression numbers are great.
Mine were 160 - 165 using a low grade tester.
Then I took my engine apart and found that the, 20,000 mile
since, recond motor had 1 broken top ring and all the other
top rings had worn the sides of the piston grooves. The
other pistons grooves and rings were fine hence the great
compression.
The cause was badly gapped top rings.
The motor idled and drove well even with the above.

Jim and his soon to be re reconditioned motor.
