Fireman-hott Posted November 29, 2006 Report Share Posted November 29, 2006 If it was a bitch to start you probably need a bigger pilot. SOmeone will chime in eventually. Quote Link to comment Share on other sites More sharing options...

Banshee_19 Posted December 2, 2006 Author Report Share Posted December 2, 2006 here's the deal, just pulled my plugs and found them to be leaner then it was in the summer. Quote Link to comment Share on other sites More sharing options...

DuneRookie Posted December 5, 2006 Report Share Posted December 5, 2006 (edited) you will run leaner in cold and richer in warm...cold air is dense so more of it...warm air is thinner so less air = richer. ever watch heavy airplanes try to take off on a hot day. takes a lot more runway than on cold days.....best bet is if you are running on warm days with out bogging then no worries. Richer is better. for colder days do a plug chop and adjust as needed....... :beer: Edited December 5, 2006 by DuneRookie Quote Link to comment Share on other sites More sharing options...
Ducman Posted December 6, 2006 Report Share Posted December 6, 2006 -20*C = -68*F Dude! Thats insane. Do you live above the arctic circle or something? I woudn't even leave my house if it was even below 20*F. As a rule of thumb if you are jetted perfectly then every time you drop 30*F approx 16.6*C then go up one main size. That is typically only used from 90*F down to 0*F so summer jeting could be 3 main sizes leaner than winter jetting in very cold areas. I don't know how accurately that applies to -68*F that would be 5 main sizes larger than summer jetting if it is 90*F. As for the air temp rich/ lean question, when the air is cold and dense your motor pulls in more total air molecules. The main jet in the carb still puts out the same amount of fuel so the combined mixture is leaner; same amount of fuel + more air. Quote Link to comment Share on other sites More sharing options...
