Cardinal Grammeter Posted July 22, 2014 Report Share Posted July 22, 2014 I got 3 of them started and none of them were easy - I had to use finger tips to get them started on the studs. But the LR stud which is obscured by the BCDD and the vacuum diaphragm is simply impossible. How do people do it? I could make a little room by disconnecting a coolant hose and/or removing the BCDD solenoid. But it may still be crazy difficult. So how do people do this? (Maybe there is a reason people put Webers on, huh? Quote Link to comment
datzenmike Posted July 22, 2014 Report Share Posted July 22, 2014 Loosen them and lift the carb up and finish undoing them. Same putting them back. I also ground down the shoulders on the open end wrench to be able to turn it farther before jamming. It's a bitch, I know... Quote Link to comment
datsunaholic Posted July 22, 2014 Report Share Posted July 22, 2014 I have relatively small fingers, but to get that PITA one, I've had to balance the nut on the carb flange, hold the carb up 1/3 to 1/2 inch, and start it that way. 1 Quote Link to comment
bananahamuck Posted July 22, 2014 Report Share Posted July 22, 2014 Put washer and nut on long skinny screw driver , hold them up and put tip of driver on center of stud, let nut/washer fall onto stud. Hold the screwdriver in place while you spin nut with one finger,, till it catches. 1 Quote Link to comment
Cardinal Grammeter Posted July 22, 2014 Author Report Share Posted July 22, 2014 I haven't looked into the details, but is it simple to unscrew the BCDD solenoid? Or will some parts "fall out?" I like the idea of holding the carb up and start with that LR tough one first. Did they use separate nuts and washers or did they use a washer nut? (I have a couple washer nuts and may use one of them on that LR stud - one less part to fumble AND its probably easier to maneuver a nut with a flange.) Might even make a little spacer to set the carb on to keep it elevated until all the nuts are started... Quote Link to comment
danfiveten Posted July 22, 2014 Report Share Posted July 22, 2014 I just replaced my stock carb about 5-8 times when trying to fix it. As mike said. loosen rest so right at end. pull teh carb up, use ur finters to get on and threaded, and then take your time with a wrench taking forever. Best way to do it i found out is to heat up a wrench and bend it so its easier to get in there. Quote Link to comment
Cardinal Grammeter Posted July 22, 2014 Author Report Share Posted July 22, 2014 I thought of another thing to do: be absolutely sure you have nice smooth threads so you can spin the nut on when it is started. I think the washer nut will also be an advantage since it will have the additional washer feature to reduce the dreaded "side fumbling!" Quote Link to comment
scooter Posted July 23, 2014 Report Share Posted July 23, 2014 I hate these. I ran around for a while with 2 nuts holding the carb on because of its evillness and lack of patience trying to get those nuts started Quote Link to comment
Cardinal Grammeter Posted July 23, 2014 Author Report Share Posted July 23, 2014 Oh I thought about that one! I can get 3 on but that last one is .... truly EVIL Quote Link to comment
DanielC Posted July 23, 2014 Report Share Posted July 23, 2014 Carb wrench. I have found if you start the most difficult nuts first, then do the easiest ones last, it is easier to get the nuts started. Put the flat washer, and the lock washer on the manifold stud. Then hold the carb off the manifold, and slip the nut on the top of the stud, and carefully start it. tighten the first nut only enough to prevent the washers and nut from falling off. Maybe two turns. Then do the second most difficult washer, lock washer, and nut. After all four flat washers, lock washers and nuts are started, tighten the most difficult to reach nut first, and again tighten the easiest to reach nut last. Quote Link to comment
Cardinal Grammeter Posted July 24, 2014 Author Report Share Posted July 24, 2014 Washer, locknut, and nut - that would scare me - too many parts to fumble. I'm really leaning towards Solid Flange or Spinning Washer Nuts. The thought of stacking anything under that nut is terrifying! Quote Link to comment
Cardinal Grammeter Posted December 11, 2015 Author Report Share Posted December 11, 2015 My Conclusion: Remove the BCDD - its only 3 screws. I had to free up the adjusting screw in my BCDD so I removed it. When I looked at the carb with it removed, I was compelled to remove the carb and check out some stuff on it. And while still, some of those studs are tough, they are doable. Quote Link to comment
