    Tuning the Zenith 12566 carburetor on a 32 HP 1/2 VW ...

    Yup ... when I was 16 (back in the '80s), I bought a '67 VW beetle with the PICT carburetor. I rebuilt that and tuned it with no problem. But I was confused about the Zenith Carb for exactly the reason you mentioned. I read that the idle air adjustment screw was clockwise to RICHEN it, and I...

    What did you do on your airplane project today?

    Well ... this is nothing exciting like the other contributors, but I rebuilt the Zenith Carburetor on my 32hp Hummel 1/2 VW. Very simple carb, easy to rebuild. It reminds me of rebuilding my VW carb when I was 16 ... LOL.

    Tuning the Zenith 12566 carburetor on a 32 HP 1/2 VW ...

    Hi Folks: I have the Hummel 32 HP 1/2 VW with the Zenith 12566 carburetor (68 series). The guy who owned the plane before me, his airport was at 50 feet above sea level. My airport (Seeley Lake, MT 23S) is 4250 feet. I don't have a manual for this engine ... and I don't know if Scott even...

    Rotax 600 / 900 ACE snomo conv

    Thanks for your response. Here is another link to a Ski-Doo with that engine: https://powerworldsports.com/Showroom/2020/Ski-Doo/Snowmobile/Tundra-LT/Tundra-LT-600-ACE The specifications section tells us a little more. That 40 kg (88 lbs) probably doesn't include exhaust, cooling or...

    Rotax 600 / 900 ACE snomo conv

    Anyone hear anything new about the 600 ACE engine converted to aircraft use? I'm looking for a lighter alternative to the Phazer. Anyone know the specs of the 600 ACE? Thanks.

    Tuning a Zenith 14992 Carb on a 1/2 VW

    When you changed over to dual carbs, did you put on a different prop? Or did you get that increased climb from ONLY changing the carbs? I ask because I'm thinking of swapping my 1/2VW to dual carbs like you did. Thanks!

    Repairing a small crushed area of plywood leading edge

    I have a J3 Kitten Ultralight with wooden wings. The spars are upright boards. The main ribs and front D-Cell nose ribs are made of very thin strips of wood glued together. It's a beautiful work of art. The front D-cell is made of very thin plywood glued to the front D cell nose ribs. The...

    Deregistering a plane?

    Thanks for that link. So ... I just send a letter, requesting the de-certification? Is there anything else involved? Has anyone actually gone through this process? I'd like to make sure I've got all my ducks in a row before buying this plane. Thanks!

    Deregistering a plane?

    Hi Folks: I'm looking to buy an ultralight that was registered because the owner built it up heavy. I'm thinking of buying it and stripping it back down to be as light as it was designed to be (smaller engine, landing gear, less fabric, etc). Basically, the only thing that I won't modify is...

    I know ULs don't require a pilot's license, but...

    I got airsick on my first 2 lessons. Puked in the bag both times. Calm winds and simple maneuvers. Drove me up the wall. I was really worried it would get in my way of accomplishing what I needed to do. I decided that I had to become a "man of motion" again after 25 years of working behind...

    Sport Pilot Training?

    Well ... I'm willing to train in any LSA that's legal for the Sport Pilot license checkride. Then next spring, I'll buy a KitFox, Highlander, something like that. Do you have a CFI in mind?

    Sport Pilot Training?

    Hi Folks: I'm looking for Sport Pilot training, and can't find any CFIs willing or able to do the training for that kind of license. I can't do the Private Pilot license for medical reasons. My plan is to do most of my training here locally in a Cessna 150, and also pass the written exam...

    Repairing fabric tear on plane covered with non-standard paint

    Hello: My apologies for letting this thread lag. Here's an update: I called Better Aircraft Fabrics in Alaska, the US distributor for Oratex. They make repair patches that are just peel and stick. You don't even have to heat it up or anything. Sticks to any paint, and creates a permanent...

    Can you link to an example of this? I'm having a hard time imagining a quick-remove wing tank. Thanks!
