[ENTDOC]

everything I have read indicates that the main circuit does not come untill 2500-2800, but if I have learned anything from working with webers it is that nothing is black and white. If you have not tried the smaller idle jet with your other changes that is still what I would do first. If you have the larger holders in hand I suppose it really does not matter what you try first. Always look at timing when making changes and play with the idle screw a bit also.
