Just a little FYI for any Solo owners out there that run into any carb issues...
I was having intermittent fuel leakage (directly from the carb intake) which then evolved into heavy loading in the revs. I tore down the carb and found a pretty big piece of crap laying on the diaphram. I cleaned everything out and re-assembled, problem went away... Until the next day.
Called up SM and spoke to a tech. His initial thought was that the diaphram was bad and blamed the fuel quality "now a days". Long story short, I ordered up a carb kit and the problem was indeed the diaphram. The old one would make a "pop" or "crackling" type of sound when I pushed on it and wasn't returning to it's correct shape when manipulated.
I'm glad the problem was easy to resolve but I'm a bit surprised the diaphram crapped out so soon, as this is only the second season since new. I always run non-eth, amsoil sabre and seafoam. Is fuel these days really that bad? Could the seafoam cause any premature wear on the diaphram? Maybe just a bum part from the factory.
