Should we be backing off a bit and then retorqe? It worries me too to not retorque. The VW engine likes to be torqued properly.

You torque the case while rotating the crank to make sure a main bearing hasn't jumped off it's locating dowel pin. Piston drag will mask the symptom until damage is done. Good way to ruin parts without even running the engine. Rick Girard On Sat, Jan 8, 2011 at 11:14 AM, George Bearden wrote: > > > John makes a real good point.

After a good pre-flight check I took off to the south. I was full throttle and about 400' agl when the engine went to idle. By the time I determined my throttle cable had broken, a 180 turn to the field was not an option so I picked an opening in a field straight ahead and landed. After a walk to the highway and a couple of calls, I had some help show up. We got the plane out by folding her up and setting the tail on the truckbed for the ride back to the airport. I discovered the main throttle cable had not broken, but the soldered ferrule on the end of the main cable inside the splitter had failed. After seeing how the cable splitter works, (I had never opened one up before this) I am interested if anyone else on the Kolb list has ever had this happen? It's something you will not catch on a pre-flight. -------- Jimmy Young Missouri City, TX Kolb FS II/HKS 700 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=326058#326058 Attachments: http://forums.matronics.com//files/photo_0045_181.jpeg ________________________________ Message 10 ____________________________________ Time: 05:40:16 PM PST US Subject: Re: Kolb-List: throttle cable splitter failure From: Richard Girard Jimmy, I take it that the ferrule slipped right off the cable. Was the ferrule soldered, swedged, or molded? If it was soldered, can you tell if it's a cold solder joint? Do you know who supplied them?

Chesterton ________________________________ Message 11 ____________________________________ Time: 08:32:25 PM PST US Subject: Kolb-List: Kolb/Jabiru carb overflow From: "Frankd" Hi guys, looking for suggestions here about the 94/40 Bing Carb on the Jabiru 2200 engine. I have started my engine but am getting fuel overflow at idle. I switched out the float needle valve as recommended with the black tipped one and cleaned out everything I could around the needle valve area. It still overflows at idle. Any ideas on how to fix this and what the issue may be? My thoughts are:- a/ the floats are getting stuck somehow in the bowl. b/ The needle valve seat still has some microscopic fibers or something I can't see. c/ There is a blockage of vents causing an air pocket and the floats are not fully lifting (one would think the overflow vent would stop this) Any ideas and suggestions for a fix are welcome Thanks Frankd M3X Read this topic online here: http://forums.matronics.com/viewtopic.php?p=326078#326078 ________________________________ Message 12 ____________________________________ Time: 09:21:06 PM PST US Subject: Re: Kolb-List: Kolb/Jabiru carb overflow From: Richard Girard Frank, have you checked to make sure the float arm is parallel to the base of the carburetor body when the needle valve is seated? If it is past parallel, i.e. the ends of the arms are closer to the body than the pivot the fuel level will be too high and let fuel overflow. Have you checked the fuel pressure? Are you running a boost pump? Is it the correct model that limits fuel pressure to less than 4 psi? Assuming you have a boost pump, remove the float bowl and see if you can shut off the fuel flow by pushing lightly on the needle, then try the same by pushing on the float arms you could have something keeping the float arms from swinging freely. I looked at the picture of the pink tipped needle that you posted and it appears by the marks on it that it is seated properly, but all it takes is one imperfection to make it leak. Get a magnifying glass and look the brass seat over carefully. If in doubt replace it.
