Hi,

I have a Rotax 503 but it has a single ignition system and a single carb. Does anyone have a maintenance or repair manual for this engine. It's in nice shape but I'm planning an overhaul just because. I guess it is much closer related to a 447 since it is a single ignition.

Any info on this engine would be helpful.

Thanks.

    Some manuals are here on this site but I think they cover the latter duel ignition version see link,

    You will find info about the single ignition on the CPS web site along with lots of other info...look down the list on the link,
