I recieved the part in a remarkably short time...so top marks for that. However, the spindle that went through the centre of the part was broken rendering the part useless. As time was absolutely of the essence, I took the valve apart and removed the two neoprene seals and fitted them to my malfunctioning anti stall valve, which fortunately did the trick and got it back to functioning properly. However, if I'd needed the who valve that I'd ordered, I'd have had to send the broken part back to you and order another one...which would have been calamtous for me in the situation I was in...ie, waiting on the part so that I could complete the sale of my $50k yacht. As it was, the buyer had two other options he was looking at and was ready to buy one of the alternatives if I wasn't able to get my engine running.
