I have been chasing a problem with my RV-6 that has me about ready to wish that Wilbur and Orville would have stuck to bicycles.
My plane has developed an intermittant power interuption that I believe is fuel related. I have diassembled the carburetor and found no obvious problems. The fuel system seems to be plumbed properly and fuel pressure is good with the engine driven pump. Keeping in mind the SB on the fuel pick-ups, but this problem occurs irrespective of the tanks being topped or at half capacity. I did check the tank vents and they are clear
I have pretty much ruled out ignition, as there is no improvement by switching mags. However, just to make sure I have checked the P-leads, and switch finding no anomolies.
My RV-6 was certified in 93' with a new O-360 and Hartzell C/S prop. All accessories were also new at the time. This plane has less than 100 TT, but all components seem to have weathered the long periods of inactivity.
The problem seems to be exacerbated once the engine has come up to operating temperature, and is most noticable if the engine has only been shutdown for a few minutes. Additionally, pre-takeoff run-up is fine, and it only happens under flight conditions.
One of the members of my RVators group advised me that Vans was familiar with this problem, and recommended a "Mooney Mod" to the carburetor, which fixed the problem. He did not elaborate on what the mod entails, and I was wondering if anyone here had some ideas, or experieince with a problem such as this?
