How much timing is the maximum I should run on 93 and 100 octane?
Just switched to a 170 degree thermostat and am seeing a good amount of timing. Added 4 degrees of timing and saw 23* on the log. About crapped a brick. Pulled 2 out of her and now I am at 20 depending on the weather. Air fuel ratio is 11-11.4 throughout the pull.
7.4 wot.hpl
