Thank you for doing the reboot of this topic. I've got the Holley 4150& 4160 red book and DV's How to Super Tune and Modify Holley Carburetors. I've gone through the red book and half way through DV's book. I will say that watching these videos is really helping to put the rubber on the road. I'm a kinesthetic learner, so the more hands on I get the more it will make sense. For not it's a virtual hands, but I'm looking for good junk carb to take apart and mess with to help with that learning process. Trouble is people want too much. I'd love to find someone that has a cracked carb with warn out shafts and give then $50 for it so I can play and learn. It's the details. How to remove the transfer slot restricture and how far in do you drill? Obviously it is not all the way though, so there must be some measurement that needs to be learned or communicated.

Sometimes looking out of the " box" we find solutions. Well you're working on a yeep engine. Cool. I'm working on a 4v cleveland building it for low end torque. Something the regular stream always said can't be done. Going to dyno the engine. Part of what I learned is critical is cam timing to increase velocity. Same could be done with your engine. But you'd have to have a custom cam reground. Atleast maybe 3 or 4 of them. If you plan to use your box on the street.

love your info all good stuff love the truck too. I do have a question for you you mentioned having too wide of a transfer slot causing rich issue you added a jet to the passage to control flow to it. I have exactly the same problem but lean. I have a brand new holley DP on my engine I have opened up IFR slightly to point where I only out 1 turn idle screws helped very little have replaced the screw in air bleeds etc spoke with holley tech. Of corse they tell you not to modify anything. Ignition is set to 18 deg idle 38 deg total cent adv and vacuum adv hooked to man vacuum set to 45 deg with full vacuum. comes on at 8 in vacuum and 6.5 power valve. still idles perfect AFR 14.5 ish cruise ok just slight accell goes lean 15 then 16 then 17 then 18 then 19 AFR you can feel a lean stumble at 19 in sometimes. This is all very light throttle, till at 10 in vac cruising the jets kick in and kit drops right down to 14 or 13 AFR again all light throttle. cant get enough full through the transfer slot and always have this lean condition in that light throttle area. idle vac is 12in using a 6.5 PV Im no where near that vacuum when this occurs so changing to a higher PV is not going to solve this. I need to get more fuel through the transfer slot. have you ever opened up the tran slot a couple thousandths like putting a larger jet in? Exactly the opposite of the scenario you spoke of in your video.

While I agree with all this, in that you absolutely can get a carb like that 660, or anything else for that matter, to work well on the street with enough time and effort (and sometimes money), but in the end your doing things with it that it was never designed to do, evident by the fact that to make it work you have to drill and tap, or use a piece of wire ina hole, or fill with epoxy to make it small, etc... I think all the "it's not a street-able carb" stories come from the fact that it's absolutely not a street-able carb in it's stock form, and it can't be made street-able without jury rig fixes like that to make it work in a way it wasn't designed to work from the factory. There's nothing wrong with doing fixes like that to make it work for what you need though as long as you have the know-how.

Something I learned recently is they make a throttle shaft bushing tool kit to repair worn throttle shafts. It comes with the drill bit and a brass sleeve, and it looks super easy to use. I'm going to fix my vacuum secondary spread bore 750 demon. And if it works good it will save a buttload of old carbs

Without r replacing shafts, and associated issues like getting brass screws out of butterflys. Usually I get them when people have tried to replace shaft and of course it's bent coz of a hammer on the end of a screw driver. Sigh usually those carbs arrive on Friday afternoon 🤔🙄😏🙂

On an engine that's making good idle vacuum, ya know, more of a daily driver type, the IFR wire trick actually covers the transfer slot tuning too, and works best if the wire is sized to the transfer slot requirements. This is because the vacuum at idle and cruise on a stocker are much closer together than something cammed that only makes vacuum at cruise, which really negates the need for a separate circuit. Usually the idle circuit still has plenty of fuel left to do what it needs to do. I know your content is more racing oriented, but this could definitely still be relevant to lots of your viewers And don't think I'm trying to just smartass you here, you're actually the guy who turned me on to this idea in the first place! I just took what I learned from your channel and applied it to something much, much more mild than Casper. The end results I got out of my Holley outshined the Q-Jet it replaced in every single way. Economy, power, burnouts, you name it... These carbs can be made to work as good as any other in a daily with enough patience and attention, and you're one of the folks I have to thank for guiding me to that point. Thank you for the knowledge my man (And to those of you still reading this far down in this now embarrassingly long comment, if you wish to try the IFR wire trick, electric guitar strings are the absolute best for this. Precisely measured single strand wire available in .008" in diameter and up in .001" increments. Seriously can't beat it for hardcore precision tuning on a daily)

I really wanted to use my holley 4160 on my LS with a 222/232 .550 cam but it was just pouring fuel out the tail pipes I did everything I could and all I was able to get was it to idle at 700rpm and it would still pour gas , the last thing iwas gonna try was lowering the float and the fuel just started pouring out the base plate , I got so irritated with it I tossed it and just threw my double pumper on it and it's running very well now I really don't know what I'm doing I'm new to holleys but lol imagine trying to learn on a leaky 1850

I have a few ( ok More than a few) vintage Mx bikes and carb tuning is both straightforward and at times challenging. “ You are the computer “ says it all. I ran double pumpers on the street when young and just re jetted , changed and adjusted accelerator pump cams etc and got them to work nice . I was too stupid to know I should’ve failed at it .

Hello James, I do not think you were stupid, just a little lack of knowledge. That can be a good thing IMO. A lot of guys/gals won't even try to get a project done because they are afraid of failure and think I can't do that, it is too hard or complicated. Sometimes, ignorance is bliss and that is how you learn.

Hi Andy, I have what is probably a dumb question. I have a dual plane intake but my carb linkage plate is a single plane mount under the carb. This plate is 1/8th of an inch in thickness and being single plane Im wondering if pressure pulses coming back up the intake will cause interference across the dual planes, since this linkage plate does not separate/isolate the planes (allowing a gap of 1/8th of an inch or the thickness of the mount). Does this sound plausible that I could be getting pressure pulse interference?

Mate i really like your videos. Would you mind telling me what booster would be best for me I have a 351c with a mild cam dual plane intake manifold non heated with a holley 600 cfm single feed two corner idle with a 1.5 inch spacer Will an annular booster better I also have very very lean idle when cold like 16 17 afr and the when hot it can come down sometimes to 12 at idle after being in the power circut too much or some lite driving
@UnityMotorSportsGarage

The lean afr when cold comes from the fuel not being atomized and as the engine warms up the AFR falls inline.. the Annular boosters give amazing throttle response and would work well for you...

A 2 part white epoxy called Marine Tex works great on carb issues . its heat and cold proof and with stood a 48 hour test submerged in gasoline. I found it works great for re-gluing the fuel caps back on under the plastic body on thermoquad carbs . I bought it on amazon . 17.00 white box with red and blue lettering . you get a white paste in a small container and a clear glass vile of clear hardner . it's even sandable get stuff .
