Yeah the black spring I put in puts tension on the weight when the t-handle thingy is installed. So basically, pull that black spring back out and put in the long loop spring and remap it and see where it’s at?
I did install an Fbo limiter plate as well, I currently have it set to 18, so 16+18=34. Would you recommend setting it to 12-14 instead for a total of 30-32?
I'd leave the plate out. (See TTI's posts 6 and 7 together. More on this next post.)
First see how many degrees out the heavy spring engages. Note: You can actually eyeball that. Note the distributor degrees stamped on the governer plate. Double that for crank degrees.
With the long loop spring installed and the governal plate installed. Use a small pry bar (blunt brake adjuster, whatever is convenient) to move the weights. See how far it moves before that slong loop contacts and adds tension. Lets say it engages about 1/2 way up the slot and its 26* governer (stamped 13). In that case it will slow down the advance roughly 13* above initial.
You can tweak it a little by rotating the spring perches.
Now, to throw a wrench in all of this… I do have speedmaster heads and a bigger cam that I’ll be installing hopefully this year sometime, but I can always recurve it again at that point
