    Throttle linkage broke again today. :confused: I was getting ready for a cruise in and it wasn't having it. Spent a couple hours and 3 trips to the hardware store to try to come up with something stronger but no dice. We pulled the tarp off the AA and drove it up there just 'cuz so didn't miss out but it was a bummer not getting to bring the hot rod.

    This is what I had before, I booger welded it (don't judge, I loaned my machine and got it back with no tip) last time it broke but it just broke in front of the weld.

    This linkage sucked, it worked but it had too many pivot points and the little arm that hangs down, when you hit the gas, wanted to flip sideways before it started opening the throttle and eventually that bends the allthread and it breaks from fatigue.

    Obviously I need some kind of pivot attached to the manifold but I have no idea how to start designing this. Any clues would help...

    I thought about just tying the two together and using a cable to open one but I don't like cables.

    You need to have it setup to pull, not push, to open one carb and a rod connecting the 2 carbs that will then pull the other carb open at the same time with spring return

    That intake is ugly AF....pull that thing off of there next time you come over and we will make it look good. I dont have anything useful for the throttle linkage dilemma, but Mr. Stevens makes a good point. Pulling is way less stressful than pushing. Hard to achieve without breaking your rule about having everything old school, kinda like that badass quick connect/release steering wheel from the turn of the century, just not sure which century it is from! :confused:

    Heated & bent the throttle arm to invert it (so it would push rather than pull). Bent up the linkage that used to run from the hand throttle to the throttle control and connected it to a plate I made & attached to the linkage on the rear carburetor. I need to fine tune the linkage between the carbs and find a more elegant solution for the springs, that's just what I had sitting around, but it works wonderfully and looks slicker than what I had.
