Oh, OK. Yeah trying to cut the little spring is probably a bad thing to do, it is quite sensitive in its tension. If you go that route, it may be better to try different springs from a Walbro carb rebuild kit instead. I haven't seen a need to mess with the spring tension. But yeah a little tiny piece of debris getting stuck in the fuel inlet valve does mess up the works good causing the engine to run too rich or flood out even. When it happened to me, I took the regulator apart and didn't see anything causing it. But when I re-assembled it, the regulator worked fine since. So I must have flushed the tiny spec of something out when I cleaned it.
