Are you sure the mixture and whatnot are fine? Is the problem actually at idle, or do you just have to set the idle timing like that to make everything happy? > Could you please give me your thoughts on the 2 liter FI engine setup and > what I could have done different? Does the FI make any difference over > normally aspirated engines for squash and such? Carburetion vs. fuel injection itself doesn't make much of a difference on how the combustion chamber would burn the fuel. It may change the atomization, mixture accuracy, etc., but that wouldn't suddenly mean that one or the other now doesn't like quench :-). (P.S. normally aspirated just means no turbo, blower, etc., but I know you meant carbureted :-) Take care, Shad Laws LN Engineering http://www.lnengineering.com ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/ </x-charset>
