I advanced the timing some to about 22 degrees btdc. Haven't had a chance to let it run more than 5 minutes or so but it didn't overheat in that amount of time. In regard to setting the total timing, do I understand this correctly? Set the initial timing (as I now have) then turn the idle up to 3000 rpm and set the timing to 34-36 degrees btdc? Also, what is the typical idle speed setting when running a cam that has more duration than stock? My cam is rated at 234/242 @.050 and LSA is 110.
