    Thread: The all carb diet.

    1. 07-20-2008 10:18 AM #51
      you don't need a gasket between the intake mani and the head. if your mani is cut flat, just a little bit of high temp copper snot and you will never have a problem. i learned that from Dana of Dana's autosport in N.H. He raced a bunch of 8v rabbits in the 90's and had a shop in Heniker, iirc. i used his advice on my 32/36 carbed motor and never had a problem. again, i had that mani cut too.

      There was some gasket residue on the manifold when I got it, maybe I should check it with a straight edge and see what it's like.

      Heh...got a goodie coming in the mail, hopefully before the end of the summer. Can't wait .
      Might mean I have a dual sidedraft setup for sale, now that it's finally perfect, .
      It's still carb-related though...no worries .

      Yep, but I've always had a nagging doubt in the back of my head that my dual carb setup goes against the plan I have for the car. I'm more concerned with low end driveability, grunt, and getting the best fuel efficiency I can get out of a carbed car. I'm wasting dual carbs on grandpa-driving IMO.
      I'm not dead-set on swapping them out just yet though...it's just nice to have options .

      You can't grandpa drive dual carbs. Your right foot will take over and won't let you................

      I can't keep it in any longer, this is what I'm waiting for:

      My plan was to use one of the Mikunis on it, but I can't find any Mikuni PHH pump jets . They currently have 40s, but I would need some that are a tad larger, like 48s or 50s. My Dells are emissions units with 5 LARGE progression holes, and until I see how the tuning goes on the dual setup, I'm not going to commit one of them to the new manifold setup. My other option would be to buy more carbs...twist my arm .

      Single 48 or 50 is way overkill. When you have a 1 barrel per cylinder setup, each draws through a 40, 45, 48, etc barrel. With 2 cylinders per barrel, each one is still only drawing through one barrel, one cylinder at a time. Put a single 40, maybe a 45 on that manifold and be extremely happy with it.

      Oh yeah, if I do end up running it, which is entirely possible seeing as how I just got finished with the struggle to re-balance by duals and am fed up to *makes chopping motion at forehead* here, I'll be using a 40 with 34mm chokes.
      I just got finished reassembling everything, and FINALLY have no leaks.

      Hot DAMN! I completely forgot about those guys! Thanks for the memory jog, I'll be ordering some larger pump jets, 1.8 needle valve, and maybe some 34mm chokes (if they still have any) .
      I love this forum, and GREATLY appreciate the sharing of info that isn't common knowledge anymore. for all!

      N/M...haha...I misread what you typed. Thought you wanted to swap up to 48-50mm carbs, not pumpjets.
      Guess I should read more gooder

      I just installed an old-school Jacobs Pro-Street ignition, and WHOA did it make a difference. I'm gapped at 0.040" and I was able to lean it out at idle by a full turn on the mixture screws (Dellorto fine-thread). It's idling smooth as silk and nearly 14:1! The throttle response is AMAZING, the slight stumble when giving it a quick shot at idle is non-existant now. This is before the car is warmed up too! It used to idle at 12-13:1, and wasn't super smooth, now it's easily 13.5:1 and sounds like a fuel injected car at idle.
      I'm now a believer in aftermarket ignitions on carbed cars [IMG]http://**********************/smile/emthup.gif[/IMG].
