Whats the answer? :
3K miles ago I freshened up the 1300 spit motor in my "should be a 1500"
midget.I took the block, pistons, and crank to British Automotive here in
Eugene to
have them look and see if I needed a rebore and regrind. No they said, all are
fine, the crank has been ground 20 thou under already. So I put it all back
together with new bearings and rings but same pistons. After I had run it in,
I was not impressed with the performance. I had larger inlet valves, an SK
carb, a kent cam, tubular exhaust manifold. but it appeared to drive just as
before.It has been stored for most of the winter and I deceided to drive it
yesterday.
I was curious if the compression was OK. SHOCK, HORROR.
Dry test= 110 +/- 3lbs on all four cylinders.
Wet test= 185 =/- 4lbs on all four cylinders.
I was maticulous when I put it together and during the break-in period.
Could it be Brit Auto screwed up?? I wonder if honing the bores and bead
blasting the pistons would cause this.
Also 15K before the rebuild compression was 145lbs.
Anyway I'm pissed off now!!
After a rebore and new pistons would a dry comp test be anywhere as high as a
wet test???
Cheers DW
