yes Gator I had that valve on my loader but broke it I was so pissed even with replacement parts from Brand It couldnt be fixed..went back to a STD cylinder valve for my motor..hard to operate if you dont feather it...so want to get another but at 431 bux its gonna haveta wait, I think when I bought it the first time it was around $350..anyway maybe if Kevin were to jack the Cadtrak up and run it a bit in drive fow/rev it might clear up? even if it would self-purge,maybe some air in the system between motors? just an idea
