OK, I,m getting confused a little. This isn't a spring mix up issue with what I have. I have a mismatch in springs for the coasting richener diaphram within the same carb set. I know the springs that go on top of the needle valve and they are in position and correct. I have two sets of carbs for a total of 4 individual carbs. What I'm trying to convey is that on dissassembly, I found two different length springs in the coasting richener diaphram for each set of carb assemblies that I have.
When I took the carbs apart to clean them, one carb set had a long spring on the front carb coasting richener diaphram and a short spring on the rear carb coasting richener diaphram. On the other carb set the long and short springs were reversed.
Ron Ayers shows the same part number for both so I assume the springs should be the same length within the same carb set.
Between both sets of carbs I have two short - about 3/4" long, and two long - about 2" long springs that were previously in the coasting richener valves. I'm trying to figure out what spring length should be in there.
From what I gather from Crobins365 post, it looks like the longer of the two choices that I have is the correct one. The shorter one barely contacts the cap when I put it on and has very light pressure on the diaphram. The longer one takes some pressure to put the cap on. The reason I want to be sure that it's the larger spring, is that it seems to be a lot of pressure for the diaphram.
