A new test and an old problem.

Most of the engines I use on my planes, the OS .40/.46LA, come new with a remote needle valve. I use an after market needle valve asembly that has a larger diameter spray bar which restrics air flow giving me the type of engine run I'm looking for. This style puts the part that I have to turn to adjust engine RPM real close to the propeller. This morning I had the idea to use the larger spray bar with the remote needle valve. The larger unit has an open ended spray bar as the fuel goes in one end and the needle screws into the other which adjusts the amount of fuel getting into the engine. The original remote unit has only one end open so I soldered the open end of the larger unit so it would act like the ssmaller remote spray bar. I hooked the engine up on the test stand and started it. It ran very well on the stand. I'll have to try it on a plane in flight when the winds cooperate. My seven year old toilet started to fill when it wasn't supposed to. There is a leak in the flush valve seals somewhere. I watched several posts on youtube and got the parts to fix things and when I tried to take the valve apart it didn't want to budge. Snaping and cracking noises made me very wary of what is going to happen so I stopped. While sitting outside after breakfast a plumbers truck pulled into the neighbors yard. I talked to them and got a card and made an appointment with the office to have them look at the situation and fix it. We will probably go to an ACE hardware store and look at electric mowers today.
