Hi there, sorry if this post is long, I'll try to give as much info as I can to avoid confusion or questions.
Just got done rebuilding the engine in my 1964 Allis i40 Ag/Loader tractor. Throttle/governor doesn't work correctly at all. Previous owner cobbled/bent some stuff that I have since fixed.
This is the current throttle lever. It's been broken/rewelded before. I believe incorrectly. Where should the handle be in relation to the pin on the slider bar and which direction shoudl be idle/full throttle? Currently I've only gotten down as idle, up as full throttle to work.
The slider bar has issues too (I know it's upside down in the pic). When the right direction, it hits the fuel tank when moved halfway forward, with the tank removed it tilts down in back, sharply up in the front when moved all the way forward. Need to know how to fix that.
I'm assuming the rod spring goes behind the slotted tab, due to the 2 pinched stops on the rod itself. Just want to clarify that.
Which direction should the arm attached to the rod rotate to give throttle/idle? Currently, rod pushing forward, more spring tension gives throttle. Should it be pushed forward with spring tension at idle, then slowly released to attain full throttle?
My carburetor is of the universal style with an adjustable throttle arm. The rod I made myself, I can make a new one if need be once everything else is situated. Is the arm supposed to be pointed downward and slightly forward with a small dog leg to clear the carb body like I've seen in parts diagrams? Currently the rod pushing back is idle, rod pulling forward is full throttle. I know if the arm is upside down it reverses those directions. Should it be rod pushing back is throttle, rod pulling forward is idle?
That's all the questions I have, huge thanks to anyone who reads the whole post and/or provides helpful insight.
Sorry if the post is too long or in the wrong section. It is an industrial model but is an Ag industrial model so I was unsure where to post it.
