That F11 is your emulsion tube. There should be a number on the part above and the part below the emulsion tube. The bottom part is your main fuel jet. The top is the air correction jet (or air bleed).

40mm venturis are a little big but I have them on my DCOE 48 on my stockport 12A and it runs alright (I'm switching to 38mm shortly). Your gonna get a bog if you stomp on the gas right off the bat no matter what but you should be able to ease on the gas and get to full throttle.

BTW let me know what your numbers are and I'll check mine tomorrow (I forget what I have in it) so that you can at least get a starting point. Mine is in need of tuning cause its way too rich.

How about using a rotary phone for techinical assistance. ;)

i cant even granny the throttle befor it bogs, takes me 20 seconds to get to 60 mph if i dont want it to loose power and bog

i guess the carb guru's dont feel like helpin out lately! damnit i dont wanna have to take it back to mazsport and get reemed

thats the right jetting... did you try adjusting the float level?

yes i bent it down a tad and it didnt change anything

i'd say screw it and leave it at mech but ive droped $1900 now with labor for this thing.. i could of had a 13b put in for that. I'm at a loss for words at this point.

well the carb is fine, it just needs some adjustments.......adjust the float some more... it should change one way or another

Rob, call me.

Hey 680RWHP12A, I see you are affiliated with Rotary Shack. I'm looking for a pair of 38mm venturis for my Weber DCOE 48, do you carry them and if so, how much? I found the carb kits and intakes but didn't see a section for parts. I'll be needing some extra jets as well when I get to that point.

Thanks,
Tom

adjusting the float. k, but... should i keep pushing it down more ? and more?

I know this may sound stupid, but my IDA did that when I had my wiring to the distributor wrong. I had the leading and trailing switiched....tried to quickly open the throttle and it just went BAAAAHHHHHHH! and would die....you may have a look see to make sure.

Dude
No disrespect but you need to buy the weber book and go from there. if you dont understand how it works, then everyone's advice is useless.
