Camelwagon Posted August 23, 2005 Share Posted August 23, 2005 Is it possible to lean out the fuel/air mixture? Please let me know how, thanks. Quote Link to comment Share on other sites More sharing options...
ausubaru92 Posted August 23, 2005 Share Posted August 23, 2005 If by 'lean' you mean change your air/fuel mixture so that there is a higher air percentage than fuel, stoich is around 14.2:1 and it involves tweaking your mixture screw and/or playing with the jets. But be warned, running too lean will make your engine run hot and you could melt a piston or two Why do you wanna lean out your carb? Do you think it is running too rich?

Ross Posted August 23, 2005 Share Posted August 23, 2005 If by 'lean' you mean change your air/fuel mixture so that there is a higher air percentage than fuel, stoich is around 14.7:1 and it involves tweaking your mixture screw and/or playing with the jets. Corrected, sorry im being fussy. :-p Quote Link to comment Share on other sites More sharing options...

Camelwagon Posted August 24, 2005 Author Share Posted August 24, 2005 Well I failed emissions so I'm wondering if that had anything to do with it... Quote Link to comment Share on other sites More sharing options...
Ross Posted August 24, 2005 Share Posted August 24, 2005 What colour are your plugs when you pull them out? They will be very black if its running rich. Quote Link to comment Share on other sites More sharing options...
Camelwagon Posted August 26, 2005 Author Share Posted August 26, 2005 They were kinda brownish, nothing darkish. Quote Link to comment Share on other sites More sharing options...
edrach Posted August 26, 2005 Share Posted August 26, 2005 Brownish is good. Did you fail HC's at idle or cruise? They were kinda brownish, nothing darkish. Quote Link to comment Share on other sites More sharing options...
Camelwagon Posted August 26, 2005 Author Share Posted August 26, 2005 At idle. High HC. I had it checked by an emissions dude yesterday and he said i am not getting enough fuel in the carb, he turned the mixture screw either way and still very high HC's. Said i have a miss too.
