Thanks again for all the help @t150vej !

I had to bend that tab quite a bit only because it was bent the other way (by the previous owner) with the old valve which the spring did not work on.
So, with the float on top and horizontal (valve down and fully seated but spring/plunger not compressed) the bottom of the float is parallel with with the body of the carb.


More tests:
If I flip it 180 degrees, so the bowl in hanging down, valve not seated and then gently push the float with my finger up till the valve seats w/o compressing the spring/plunger, it's parallel with the body of the carb, just like above.

If I flip it on it's side (manifold mount on table, air filter mount on top) so the valve is on top and float hanging vertical (like in POST#23) and measure from bottom of float to body of the carb I get a measurement of .466". Not sure if this tells anything, but thought I would just add as a data point.

Does this all sound correct and as things should be? (fingers crossed)

 

Looks like you have a good handle on it

The pin spring is very light and with the weight of the float upside down like the photo, it should be compressed. If it's parallel with the manifold side down, as when you measured, it should be good. Do yourself a favor, leave it upside down, float on top overnight, and go back over it tomorrow to your satisfaction. I think you'll be good to go.

Have a friend with one of those on his Shovel. He hasn't started it in years, but I'm certain all the info in this thread and your input and measurement will be a great help to others down the road. Good job!

 

Again, thanks for all the help. I'll do that and double check tomorrow.
Cheers,
