    Somewhere on here is a formula for finding the best cfm's for any engine. According to that 150cfm is good for an F head. The Red Line is 150.

    I would stick with the original Carter if at all possible. I rebuilt my original a couple of times and still couldn't get it to run right. I bought a Solex and was unimpressed so I went back to the Carter. I finally had a professional shop rebuild it where they had the equipment to truly tear it down and put in new bushings, etc. I think the problem was the bushings were worn down allowing air to pass through and no rebuild kit I found contains that type of stuff.

    Anyway, the rebuilt one works fantastic. In my humblest of opinions, it is worth the investment to have the original professionally redone rather than retrofit some sort of other carb.

    Ah, that's the question.

    Personally, I think your best approach would be to have the Carter rebuilt by a shop that does these regularly. Carburetors bodies wear out, and a professional rebuilder can refurbish them. They also know which parts to pick to restore original performance. The Carter YF was regarded as a pretty good carburetor, and I suspect most complaints about it stem from low-quality rebuilds.

    The Weber has been used by a few people here, and seems to work well. However, the 32/36 Redline supplies is a progressive carburetor. I'm not sure if it's a mechanical or vacuum secondary, but I presume it's vacuum. As such, the secondary will open only when there is sufficient air flow to make the vacuum signal required. With progressive carburetors, you're operating on the primary most of the time, and the secondary is added on demand. Thus they can set up the secondary opening so that the carburetor works well with a small displacement engine.

    If you want to experiment with other carburetors, the list I posted above might be a good starting point. Throttle body fuel injection is another alternative - a GM Rochester throttle body from a GM/Pontiac 151 is one possibility, or an AMC 150. The 134 is a 2.2L motor, so any carburetor or throttle body from a similar-sized engine could be considered. Your 151 TB would be a performance upgrade, and could work well on this engine when driven by, say, a Megasquirt board. Very well within the DIY universe. Hamilton will develop a bolt-on kit for you, if you want a commercially available kit.

    I agree to this. I had my jeep running poorly, then the carb was rebuilt. not by a shop, but by a guy who had done some when he was in highschool/college. that rebuild lasted a year.
    last year I replaced the fuel system in my jeep and had a GREAT guy rebuild my mechanic because he said it wasn't performing up to snuff. now, I have so much pep in my Fhead step, its ridiculous.

    Solex comes from India, I believe.

    I rebuilt my stock carb and it works good, I replaced the shaft bushings after the first try and it got a lot better. I don't remember where I got the bushings, but they made a difference. I bought a rebuild kit on E-Bay and nothing worked, I wound up using all the original jets and needle, and used only the gaskets, they were not real good but I got them to work. My motor has no carb issues.

    I have an old Solex which works well, Solex is\was French and this model is on many French cars of around 1960.
    So it seems that we have good parts and specialists here.
    In USA I would use a good Carter using local specialists.

    Always used the b series rochester off of late 1950 chevrolet with manual choke.

    You have to get the right bolt pattern I thank there are two different ones.

    Ran great never any problems. We used the one with fuel inlet in the front of the

    carburetor.
