I got the new intake manifold installed and got everything put back together. Started up on the 2nd pull. Now, it's working too well. The RPMs sound way too high. I've adjusted the throttle a little, but haven't really noticed much difference. Is there another way to make a bigger change to the engine speed?
Yes, the end near the carburetor was heavily cracked and I think part of it may have been missing. The new one fit perfectly and seemed to fix the original problem.
I finally got a chance to adjust the governor spring some more. The tab that the spring hooks to is back far enough that the spring is totally slack. However, the RPMs still seem too high. Is there another part that could be out of whack that's causing this condition?
