I am having a problem locating this locally and few places on the www carry it. Is there an approved substitute or "local" store/chain that might carry it? Thanks, John ________________________________ Message 2 _____________________________________ Time: 01:49:22 PM PST US From: PWilson Subject: Re: RotaxEngines-List: Loctite 221 --> RotaxEngines-List message posted by: PWilson I would advise you to call the loctite tec support guy. The 221 is not available in North America. but they have a close substitute. As I recall I the local distributor had to make a special order to get the correct product. The phone number is on any loctite container.

We got ours from the local Fastenal distributor. You can also get it from Lockwood Aviation for 1.99 for .02 oz, 19.17 for .34 oz, or 44.95 for 50 ml. ________________________________ Message 4 _____________________________________ Time: 03:43:43 PM PST US From: "Martin Hone" Subject: RotaxEngines-List: RE: RotaxEngines-List Digest: 582 Cold Seizure --> RotaxEngines-List message posted by: "Martin Hone" Ray, Is the engine nipping up at the end of the run, like when you start to pull the throttle back ? If so, then you should check the position of the needle clip. As you pull the throttle, the fuel flow from the main jet gets restricted by the needle. It was a common problem back when we raced 2-stroke bikes. Would be fine when flat out, but roll off the throttle at the end of a long straight, and it would seize. I would raise the needles up to make richer for the run-in period. Cold seizure is what happens when you fail to warm the whole engine. Sounds like it would be pretty warm after 59 mins.

I would say the return line is a must. It's purpose is to return any vapour lock or air bubbles back to the tank. I can see mine while I am flying and there are bubbles going back to the tank in a steady stream. Not a lot but they are there.

No problems with that set-up, except during re-starts on hot days. In such cases, the hot engine and the lack of air going through the cowling will create vapor lock, which will make it difficult to re-start. One way is to take the cowling off, so that the hot air can get out. Another way, we just learned from a Rotx shop is to switch on the electrical fuel pump, keep it running for 3 minutes, switch it off, push a throttle ever so slightly forward and start (without choke). Works well on the D40 in our flying club here. I haven't tried that yet on my Zodiac.
