Serial number to verify ASTM engine?
Thanks for the info,
Is there a way to check via serial number if it is PRE or POST standard 912 ASTM standard issued engine?
OR
Is there one or two specific clues to point us in the correct direction on the ASTM engines? Is the oil tank connection the only one?
Regards
Rudi

Get these also
Tell the dealer that you want the slipper clutch and the soft start module..
http://www.rotax-owner.com/reviews/reviews.htm. Some older serial numbers don't have the slipper clutch.

A sticker?
Hmm OK where is the sticker to be found?
Don't like to rely on a sticker on a used motor, hope it is still there
Serial number or another method would be better.

ASTM 912 Engines
Rudi,
If you go to my earlier post above, click on the rotax website and look up the ASTM certificate it states the engine nos from which the ASTM certificate applied. If the engine has a number before these it will not be covered by the ASTM certificate.

912ULS Oil Fittings
Does anyone know of a supplier for Oil Cooler Nipples, 956-641, Oil Pump Inlet Nipple and Oil Return Nipple, 956-650 other than Lockwood or Leading Edge. The fittings are $69 a piece from them. My engine has the old style barbed fittings and I would like to go with AN hoses and fittings.

OIL RETURN NIPPLE
I'm helping out a neighbor building a -12. He cannot locate his oil return nipple to replace the banjo fitting the engine comes with. Does anyone remember where it was packed so he could look there?
