Wullie 1 Posted September 30, 2010 What direction do you turn the adjusment screw to weaken the mixture on a KR engine with K-Jet fuel injection. Mine is running as rich as a very rich thing that's just won the lottery but I don't want to turn it the wrong way. I haven't got access to anything at the moment to check the CO2 emissions.

aide 0 Posted September 30, 2010 fairly sure its counter clockwise to weaken, you'll need a long 3mm allan key. from bitter experience i know its very sensetive to slight adjustment turns, shouldn't really do it without a gas analyser! Quote Share this post Link to post Share on other sites
Erny 0 Posted September 30, 2010 Try unplugging your cold start maybe, there's acproblem there and the fifth injector is continually adding fuel Quote Share this post Link to post Share on other sites
