Weber dcnf 42, Are they to big for 1.8? Options

[914fun]

Will weber dcnf 42 be to big for a stock 1.8 lt? Im taking off the D-jet system. Ben fooling with it for almost 3 years now. Done spending time and money on that system. So its time to spend time and money on a carb system. I plan on using my dizy for now. Im thinking the 34 would be to small. From what I read the 40 work well but I found some 42 that are at a good price. What do you guys think?

...so you mean that the barels go left-right instead of front to back as on a type 1 and 4?

Yes.
I talked to the man himself extensively on the DCNF's when I bought my complete 2007cc T1 kit from him almost 20 years ago. Seems that there was 30-40 different DCNF models over the years and all but a few were made with passages way too big for the type one. I had another set (not Berg) on my T3 and they always cut out bad on a hard left, right turns didn't seem to affect them as much.

For a Type 1 cruiser they are the ultimate carbs. Gene didn't even recommend them for drag racing. He preferred the IDA on race engines.

BTW I put my O2 meter on my Berg DCNF carbed engine, perfect 13:1 AR throughout the entire operating range. You can see these carbs on my Pinesol Carb cleaner thread.

Also a local guy Dave Shire (sp?) had them on his 914, he did every mod he could find including the Grosse ball jets. I don't think he ever got it to run right.
