Oil tank plug.

What is the thread type and size to cap off the return line on the oil tank for the initial filling. It would have been prudent for Rotax to include a cap in their engine delivery box so builders would do a proper job filling the engine with oil without wasting time chasing up this cap.

Hi aussi, I am not familiar with Rotax engines but if you have not investigated this option yourself yet, the distributor for Rotax has a website that has full parts lists in PDF. See if this helps http://www.bertfloodimports.com.au/

other members of the forum may be able to assist further if you mention engine type etc. (maybe the plug is generic, like I said, I am not familiar with Rotax) Good luck.
