I have been dogged by compression problems for ages.
1. I have fitted new barrels.
2. New pistons and rings.
3. The head was fitted with new guides and valves (not by me).
4. New small ends
5. The head was carefully torqued-up.
6. The tappets were gapped and re-checked.
7. Oil is flowing well, new oil pump and release valve.
I did a compression test on the right cylinder...60psi.
Did it again 105psi...great things are looking up!
Repeated the test on both cylinders...doom and gloom-50psi.
I went to my uncles garage and asked if the compression gauge could be checked against another one.
He said, "after a rebuild like that, low compression is not unusual...sometimes we have to tow them to start them. I bet if you start it up and run it for half an hour, it will be OK. Do you think you broke the rings?". No.
"Put the plugs in, if its leaking via the head gasket, you will be able to detect it".
Your wisdom would be appreciated.
I.E. should I start her up or strip it down again?
Several thoughts occur...did I break the rings while fitting the barrel. Is the head/barrel warped. What did I do wrong?
