As the holes are on top of the butterfly valve I think the issue is when the valve is closed. There's no air flowing by "pulling" fuel/air mixture out of the holes. Instead there's a flow through the idle circuit. This will probably have the opposite effect meaning it will suck air through the holes making the idle leaner. The smaller and the less holes the smaller this effect. Maybe the issue of the quote is the wording and our understanding as it does not say 'richer' and 'leaner' but 'richer' and 'weaker'. However I still don't completely get it

Frank, what is the full model name on your Webers?
There's i.e. the -107 6J or -110 7A.

a big thx to Webcon UK and Classic Carbs UK for providing some info on the Weber 44DCNF-107 and -110 and to Frank for translating part numbers into jet sizes. :thumbup:

Here're exploded views of the two 44DCNF versions:

If anyone has a fiche or calibration sheet of the -110 (or files of any other 44DCNF version used on Ducs) please let me know!

Btw. the jetting mentioned in the wsm is not the same as in the owners manual. Also what's mentioned in the parts catalog as '(US)' does not fully correspond to the US or California version owner's manual.
