Great News....She held together Just fine!....So in my eagerness to tinker...I never even bothered to to test fire my shiny new engine stock...there was a brief learning curve...first the fuel tank would only except about 2 thimble fills of fuel then an air bubble formed and could get no more fuel in....tryed to start and got pops right away but was sucking air ...probed the tank bubble with tooth pick and now she accept fuel!....a full tank cured my air bubbles....now trying to find best carb setting....she will run from 15% open to 45% open...but so far best running is about 25% open ...just as instructions direct.
   The result of the weight is much slower run....I would guess approx 1/3 the speed of stock....the side affect of this is even though my springs are softer....the rpm is still so low that the weights will not fling open hardly 1/16 inch....in videos I have watched each weight can move outward apox 1/4 inch...So my next move will be to wind some super soft guitar string custom springs and/or make more heavy governor weights....I am going to go back and try just unhook one spring to see if I can get it to miss more just for a test...but want to take the weights to work and ream 2 tiny dowel pins to accept a single spring...I think I am on the right track...but it will be a much more soft spring set up with the lower RPM. The low rpm was no issue for tape to hold weights in place...so when I get my set up dialed I will report!
