I would have thought the nut should be tight in that slot, so that when the throttle is pulled back like that, it would in turn move the outboard rods.

that shouldnt be a nut. it should be a rivot looking thingy with a washer/flangy thingy








There's been several different "repro" linkage assemblies, over the years......I know as I have several sixpack cars, .....in fact all I have is sixpack cars.....all I like to work with is sixpack cars......Ryan,with engine off, check to see if your outboard carbs may be stuck, disconnect the snap on clips, that holds the linkage on the front and rear carb throttle shafts,....you should be able to freely, with little to no effort open the throttle on the front and rear carbs,.....if not, before going into a panic, and ripping the carb off, just loosen the 4 base nuts/ bolts, and wiggle the carb around while activating the throttle shaft on said carb,....sometimes the bore on the manifold prevents full throttle activation, if the throttle dosen't move at all, remove the carb,....most likely the throttle plates are "stuck" in their bores, remove the base/ throttle plate from the carb body, 5 or 6 screws if I remember, try and free the throttle, if you susceed, use some 320 grit sand paper, and sand/ polish only the areas that appear to have galling or rub marks on the bores and throttle plates themselves,.....do not attempt to unscrew the round throttle plates from the shaft, the screws will shear, they are locked on.........if none of the above applies to your problem, and the carbs, operate freely as far as the throttle action, but still do not open, confirm that the vacumm lines are hooked up properly.......you may want to open up one of the pods on the front or rear carb, to see what color spring is inside,....if black or brown, this may be your problem, as they are "heavy" springs,.....you'll need to change them out, Holley makes a spring kit for this, you'll need two kits..........the instructions will tell you to use the next "color" down from what you have, based on the supplied chart,....screw it!.......you'll be there all day playing with springs, put the WHITE ones in each pod, go for a "run" and have at it!.....

Ryan I hope this info helps?....good luck!

One more question on these outboard carb vacuum pods .. Looks like it's easy enough to open these up w/o removing the carbs.. Do I need to be concerned about messing them up by taking off the covers? (haven't seen inside one yet - so wanted to make sure parts won't start jumping out on me).

Also, it sounds like the "white" springs are the lightest, so that would probably be my best bet to make sure my outboards open up when I step on the gas hard? Are these springs/kits easy to come by? Would I need to find a Six-Pack specialty place to order them through -- I am thinking they are probably not widely available otherwise??

Thanks a lot for all the help!!

Stan,.......the PN# for the spring kit is 20-13( Holley PN#) retails for about $10, any speed shop, Summit, PAW,Jegs,Advance Auto, etc can get them!,,,,,if you need them, order 2 kits,......nothing hiding under the pod covers to be afraid of......6 screws, gently remove the top cover, try not to disturb the diaphran, the springs kind of "snap" on a boss, located under the pod top lid, make sure the outer edges of the rubber diaphram don't rollover or become dislodged, ALSO install the cover correctly, theres a passage that must line up, you'll see a small port hole aronnd the outer edge of the pod base where the cover "seats", (towards the carb body) that small port hole must line up with the port hole in the cover, (it's possible your covers may be indexed wrong blocking off the port>)....so check!..... when you reinstall the springs/covers, after you install new springs(if you have too?) with the carb (outboard) linkage undone, check to make sure the throttle moves, and returns to its closed position on the 2 outboard carbs, if not, something happened when you put the pod covers on,....usally the spring falls off the pod cover boss, and you can't/ didn't see it happen, (I've opened brand new end carbs and have seen this from the factory {holley})....hope this helps Stan,.......good luck
