bananahamuck Posted May 13, 2014 Report Share Posted May 13, 2014 So we tried working this out using paper and felt pens but i can't seem to think it through correctly. And before we cut/grind it off to weld onto middle bar ( don't know technical name) between carbs. My question is, if my linkage cable can only pull from A to B which circle would rotate more ,,as in turn farther.. The pink circle or the blue circle I understand it is probably a simple answer but my brain is fried from measuring a million other things to use original cable that is just barely long enough.

MicroMachinery Posted May 13, 2014 Report Share Posted May 13, 2014 Blue, it will require a shorter pull by the cable to make the shaft turn more. 1 Quote Link to comment
Laecaon Posted May 13, 2014 Report Share Posted May 13, 2014 Its really hard to pedal but you go fast in gear 7 on a mountain bike, and its easy to pedal but you go slow in gear 1. Gear 1 is big, gear 7 is tiny, Gear 1 has a large radius, gear 7 has a small radius. Blue has a smaller radius. Quote Link to comment
bananahamuck Posted May 13, 2014 Author Report Share Posted May 13, 2014 I really appreciate the answers We played with it and stared at it made a couple weird test samples on notebook paper and i swear we just couldn't come to an answer. :wub: Quote Link to comment
Sealik Posted May 13, 2014 Report Share Posted May 13, 2014 Middle bar is the throttle bar You'll have more than enough rotation in the stock (blue) trunnion hole. Pulling from the top with 38s? I did the same thing...but pulling from the bottom for the 46s to utilize my 'stock' throttle cable Lower right in pic 1 Quote Link to comment
smoke Posted May 13, 2014 Report Share Posted May 13, 2014 Like a pry bar (or pen you're drawing with) the further up you push on it, the more leverage, but the less the other end moves. Move closer to the point you are prying with, the more it will move, but the less leverage you will have. Quote Link to comment

It's funny you post those pictures as those were the pictures we have been working with to figure out what we need. Those pictures show parts numbers that also helped me find out there are kits being sold by my local Nissan dealer in stock .. :thumbup: :thumbup: From this thread ,, and "your shit" thread . http://community.ratsun.net/topic/59502-prefferred-su-carbs-flat-or-dome/ Many drama queens criticize this place with every breath but with a little research this place is a treasure for Datsun guys.. We have been lurking 720world quite a bit lately though. :ninja: :ninja: Quote Link to comment
