Anybody have any Dell experience? I have NEVER used one or tuned one. I do know they require different jetting than a similar Weber counterpart.

I just finished building a 2276 for a friend and he had me install a 45mm single Dell carburetor. He will eventually switch to a dual set up when money permits but for now I need to get it running right. Any suggestions on baseline jetting for this application?

Thanks in advance,

Roy

Hey Roy call Aaron at cb performance 1800-274-8337,I was running a single 45 dell with my 2276.He got me real close,I since have went to a 2387with dual webbers,I cant remember what I had in my dell,sorry

i also got a dellorto off of dean, he might know something? But i called cb performance to get an update kit for my single dellorto 45mm and she wouldnt sell me one because they only come in kits... this kind of ticked me off. anyone know where i could get an update kit for a single dellorto 45mm? sorry for asking another question in your thread Roy, but pointless to start another.

Hey that's ok Jeff. Hopefully we will find someone that knows a little bit about them.

Roy

I found my information I was looking for. Thanks Tom.

Dont be stingy, Roy, whadya find out? What's the good baseline?

Wondering the same thing myself for a single Weber 48 on a 1915. We set up my buddy's like this and had to drill the mains out to about a 200 to get it to act right. (Already had a good set of 48's, used what we had!) Still had a pretty rough flatspot transitioning from idle circuit to main circuit, but idled good, and would go right upstairs. Will probably go with something similiar for my sons rail and would like to avoid the flatspot.

Weber jetting is completely different from the Dell. The Dell requires much larger fuel jets.
When you get ready to set up your son's carburetor, I will be glad to help you if you go with a Weber. I know those carbs. A 200 main is way to big for a 1915. Maybe you meant a 200 air jet? That is about correct.

The flat spot in the transition from idle to mains is usually due to the accel. pump squirter nozzle being to small. This is a common problem with a single mounted carb. You have to drill it out a size at a time to shoot more fuel. Remember that when this carb is used in a dual configuration, it's accel. squirter is only feeding 2 cylinders and it's close to the head. Take it and mount it in the center, the same squirter can't shoot enough fuel to feed all 4 cylinders. Weber does not sell bigger accel. jets so you have to drill them. You can buy them already drilled. It will usually take a 65-85 depending on the engine.

I'm pretty sure it was the mains. I'll ask Scott tomorrow to see if he remembers. Been a couple of years. It was the first Weber IDF I had ever messed with. We both run dual 40 Dells now, and that weber 48 and its mate are sitting on a shelf. Maybe I'll take that one apart and see what we did!?! Felt like it wasnt getting enought fuel at top end, so I got the Weber book and found where the mains were, and ran a little drill bit thru them!! Crude at best, but it worked. I have managed to learn alot about tuning dual Webers and Dells since then, thru trial and error, advice from you and others, and reading everything I come across on the subject! Not a pro yet, but I can get a set to run pretty good on most applications. The hardest part to me is figuring out what jet sizes to start with. I usually just ask Tim or Steve where to start and go from there! The "guidelines" in the Weber tuning book are useless for woodsbuggies, IMO. Everything Way too big. It seems on selecting venturii, the best way to go is smaller to get a snappy throttle response. If the right "parts" are in the carbs, the balancing with a synchrometer and tuning for best lean idle are gravy.

Single center mounts, thats still black magic to me! Not much to read about them. I know they are not ideal , because the fuel de-atomizes thru the long intake runners, but it puts a good carb. I already have to use. I'll definately take you up on some advice if my sons build goes as I am planning and we go back to a single center mount application.

I have dual dells for my buggy and found a guy in the back of hot vw down in texas,It`s called black gold vw and he claims to be a dell expert he helped me get my jetted right the first time I tried and he also is one of a few companies that has jets and parts for them,he also claims the are the best carbs out there even though they haven`t been made for twenty some years if you need me to find the number I will get it.

Hey man,

Yeah if yo

I'd like to have the number, too. I've never had any problem getting jets or venturiis for Dells from Tim (Southern-buggies), but a second source is always good!

Larry

sorry for taking so long to reply,the number is (817)633-1135 or (817)640-4653

Thanks Aaron!

i talked to the carb tech department at CB Performance and the guy was more than happy to tell me what jetting i should go with for my application. His name was Aaron i believe, give him a call. Oh, and i told him about woodsbuggy.com and he was syked haha.

Aaron know is shit I talked to him on tuneing my baby delortos duals He hit the nail on the head it runs alot better now
