The ones in it now are at least 30 years old and yellowed. They were old water treatment chemical throw-aways. These appear to be at least as sturdy as my old ones and have the bonus of little vents in the handles. If interested here is where I got them: http://www.utahbiodieselsupply.com/carboys.php Price is good and delivery fast. I also found a source that sells fluorinated tanks which are supposed to resist ethanol. A bit more expensive. Will fwd their site if interested.

Is that strange? The way it is built it looks like I will have to order entirely new senders. It doesn't look like the clamp is sold separately or that it is possible to separate the sender from the clamp. -------- Cristal Waters Kolb Mark II Twinstar Rotax 503 DCSI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=283645#283645 Attachments: http://forums.matronics.com//files/broken_exhaust_probe_clamp_106.jpg ________________________________ Message 3 _____________________________________ Time: 10:17:03 AM PST US Subject: Kolb-List: Re: broken exhaust sender clamp From: "Richard Pike" Cut the old band clamp off with a Dremel tool. Get new band clamps that will fit all the way around the manifold. Drill a hole in the clamp big enough that the probe will slip through. Cut out a piece of thin metal about as big as a dime, and drill a hole in it that will fit the probe just above the wide flange where the old band originally held the probe in place. Cut a slot that same width from the edge to the hole, slip it onto the probe just above the flange and below the new band clamp and tighten it all down. If it doesn't work, you are out the price of two hose clamps and a half hour of fiddling.

A bit more expensive. You don't need a fluorinated tank to resist ethanol, plain old HDPE will do fine. The fluorinated tanks are only needed in applications that need to be CARB compliant; the fluorinated plastic has lower permeability to hydrocarbon emissions... from the same folks who mandated "spill proof" (which are actually pour proof) as can spouts. -Dana -- A flying saucer results when a nudist spills his coffee. ________________________________ Message 5 _____________________________________ Time: 11:01:38 AM PST US From: "Jack B.

Takes a few minutes and it is inexpensive. Find a matching hose clamp. Cut away the end with the slots in it. Drill a hole through the cut solid clamp end that will pass over the probe. Put the hole end over the probe and match up the two thicknesses, and drill an 1/8 inch ID hole through both. Cut away excess solid length. Insert a stainless pop rivet through from the inside and pop it. Thread the old clamping strip through the new screw end and tighten it into place. Jack B.

Since I had it that far apart I decided to pull the engine off and go through it also... but that's as far as I'm going :-). I thought I would attach some pictures showing the pistons and head., they actually look pretty good (I thought) approx. 145 hrs. as I'm not sure if the previous owner decarboned them or not. He told me he had put new pistons in at I believe 330 hrs. Anyways, here's the pictures. You'll have to excuse the quality as I took them with my phone. -------- Tony B.
