Been wanting to add some kinda extension to keep the stand-off fuel from escaping... so I spent some time at the local true value looking for that random part that would fit the bill. A 3/8" pipe coupler fit perfect after some minor boring out with a Dremel. Used a short 3/8" screw and a vice to press into the tube to create a flared opening. Worked great today - kept the fuel off my plane and ran smoothly after some work to the high speed needle.





Got about 1/8" clearance from the prop which is penty since the blades will only bend forward when throttling up.

WOW super job hope it stays that bright looking nice flare on it martin
like your throttle rod hookup too no slop there

G'day Geek,
If I were you I would change that metal clevis, & replace it with a plastic one, or a ball link, you should avoid metal to metal contact like that, It can produce RF noise & effect your radio reception.
Also, that's an APC prop, the blades won't flex much, if at all.

Alan have done both on throttles and no issues, maybe lucky with the new 2,4 Gz radios should not be a problem if using one very good point however martin

When you watch the blade from the side, running from an idle to WOT causes the tips to move forward about 1/8".

Good thing to note on the clevis... forgot about that.

You do nice work, Somegeek.

What is holding the extension in place? Not just friction, I hope...

Thanks, Ed!

Friction(tight fit) and a silicon adhesive. I've checked it before and after a half dozen tanks with mostly WOT runs and it's not wandered from it's initial installation location... would be nice to have a screw into the carb intake wall though.
