I recently checked compression on a '74 Spitfire that I have begun rebuilding.
Although it looks fairly goog, I'm not sure what a "healthy" 1500cc Spitfire
engine should have.
My results were: #1 130
#2 128
#3 130
#4 125
Does anyone have an opinion on these measurements? Are they close to what good
compression should be for a 1500cc engine in a 1974 Spitfire?
Also, I did a tune up on the engine and set the timing to the 2 degrees ATDC
that my Haynes manual (and the decal under the hood... err, I mean bonnet)
and the engine doesn't run as well at an idle. The timing was previously more
like 8 degrees BTDC. Is my timing info wrong?
When I set the timing to 2 degrees ATDC it was with the vacuum line to the
distributor disconnected and plugged off. Hopefully I was correct in doing
so. Any suggestions?
That's enough questions for now.
Thanks for any help,
