Thanks for the explanation Jerry. Would you have a recommendation for the settings on my 261? I do pull a 2000 lb camper with it quite often. Is that considered working hard enough for the wider gap? I'm a little confused also about the settings on my son's 235. The cam is a 254RV from Patrick's which has specs on the box of .012 gap for both intake and exhaust. I thought that was too much for the intake so I have it set at .08I and .016E. Should I change to the .012 on both? Dave V
