Well, I have put about 40 hours on the L3430 I bought a couple months ago, and up until yesterday the float detent worked fine after I figured out with help from this forum (thanks) that it takes a firm push forward to get to float. Yesterday it would not stay in the float detent at all, so I cleaned the spool valve caps that were not too munged up, as my control valve --B00104-- has the caps pointing straight up. Did not help. I noticed the actual detent on the valve "pin" was chewed up just a bit, so this morning I was going to order a new cap and the "pin"( that looks like it can screw off). I cannot find a part number of the pin, (Messicks) so I am assuming it does not screw off easily, and can only be replaced with a total rebuild of the control valve. Any help? Thanks!
