Engine runs smooth and sweet from idle to full power. IMOO, when running well, leave "well" alone.

The reason was that if you have bad fuel, the paper filter will clog up and stop the fuel flow completely whereas the screen filter will still let enough through to keep your engine running. You can buy these filters at Napa part # 740-1155. They are clear and have one screen in them. _____ From: owner-rotaxengines-list-server@matronics.com [mailto:owner-rotaxengines-list-server@matronics.com] On Behalf Of Tom463@aol.com Sent: Thursday, January 15, 2009 8:28 AM Subject: RotaxEngines-List: Re: RotaxEngines-List Digest: 16 Msgs - 01/14/09 Perhaps I didn't explain the issue correctly; I'm not talking about temperature or moisture having an effect on the paper fuel filters.

I only turn off my ignition when the engine is idling and both voltage and current are at a minimum. If you install separate mag switches and use them to shut down then there will never be any voltage or current pass through your switch.

I know that the staring current never goes through the keyed switch. My concern is the current going through when the ignition is shorted out to turn the engine off. Craig Payne answered the question better by telling me how much current and voltage goes through the mag shut off (250V & .5A "minimum"). But I think I need to know the maximum rather than minimum amount. and then call the keyed/switch manufacturer to see what he says.

The switch has three positions, On, Start, Off, and Acc. It is an ordinary ignition switch. The full starting current does not go through the switch. The starting position on the switch pulls in the starter relay coil which connects the + 12V side of the battery to the starter itself.

However, given the ease of use and (limited) security feature, I chose to use such a switch. Now I am being told that it is a particularly bad idea to use this type of ignition switch on a Rotax 912 engine because a lot more current passes through the switch with a Rotax 912 than with a Continental or Lycoming. I was also told that this current far exceeds the current that these switches were designed for. Does anyone know if this information is true? I don't want to have to lie upside down under may panel for a few hours pulling out the darn switch if this is just an old wife's tale.

The task is not daunting and akin to changing out a tire. I'd not hire a mechanic to do such a routine task. The manual is all you need unless you've never held a screwdriver before.

I also have heard Phil and Dean say to stay away from paper element filters. This was based on field experience with failures. Switch to plastic mesh filters. Consider it an AD. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=224901#224901 ________________________________ Message 7 _____________________________________ Time: 07:39:14 AM PST US From: "Noel Loveys" Subject: RE: RotaxEngines-List: Re: RotaxEngines-List Digest: 16 Msgs - 01/14/09 I doubt the paper filters will have any issues with paper filters except if you are premixing your fuel and you have a phase separation at which time the engine will stop filter or not! With oil in the gas when a phase separation occurs it forms a heavy mass of off white to tan coloured sludge which I doubt you could pass through a fine screen let alone a paper filter. Water will pass through paper filters no problem... At least it does on cars and trucks not to mention my coffee maker. Water has a very hard time passing through felt or chamois while gas passes right through it... Use a good felt cloth or Chamois to filter all your fuel. BTW it is suggested to pre-wet a chamois with gasoline before using it to filter water out of the gas.
