[Roadsters] Hot or cold Adjustment

[robert k. smith]

hi steve, in addition to what dave said, i would ck. the compression of the

cyls. if the head has been machined too much, you might have a very high

 compression. i think 160-185 lbs is about average. if you are close to

200lbs., thats too high. you can still retard the timing to help the pinging.

good luck.  bob smith> From: daveandlindab at comcast.net> To:
