O.K. so I just finished the rebuild on a bone stock 2.0 Now I need to tune it. Anyone ever deal with Weber DCNF carb's? Any good tuning websites? I have the haynes WEBER manual but the procedure they give is not really working. Damn things are backfiring up the throats and when I switch the ignition off i get a muffled backfire thru the exhaust. the air correction screws don't seasm to do anything at all nor the mixture (although to a lesser extent). Any advise?

Also I have a 09 dizzy. I have it timed as per the factory spec (27deg. a/3.5k) but that is for injection and a different dizzy. I have noticed that if I move it from fact. spec the thing idles much better, stops spitting gas in my eye, revs 1k higher, and smoothes out considerably. Now I have heard the 009 is less than desirable but it is what I have and I need to make it work as good as I can. I will go Mallorry in the future but can't swing it now.

Thanks for any help

DCNF's? dont know anything bout them.

Sounds like the linkage/sync is out of wack.

PM me your email addy and I'll send you a set of very good directions.


BTW the DCNF's is not the best choice for a 914, they don't do well in the twisties due to float issues. They are great (one of the best) for a bug that see's mostly highway.
