Rotax 503 DCDI Ignition Timing Adjustments

[@DadsShop1]

Thankyou very much for this video. I was pretty close in how you adjusted the timing but I used a magnetic holder for the dial indicator and wasn't sure how the 30° offset was as far as setup. Now I need to come up with a dial indicator holder that will screw into the sparkplug hole to be more accurate. Thanks again this clarified the procedure greatly.

Glad the video was helpful. That's the reason I demonstrated what the 30 degree offset was about on the dual spark plug engine.

Glad to know I did my engine properly after watching this video. Cheers from Winnipeg.

Can you also show how to adjust contact points

[@RotacRepair]

Next time I’ve got a point 503 in I’ll video the process

@@RotacRepair nice, I’m rebuilding a hirth 2703 with point ignition

Only have to show us how to rewire lighting and ignition coils ourselves and lots of older rotax will run again.

Здравствуйте 🤝 какой зазор между маховиком и триггером (датчиком)? Спасибо

How to assemble in microlite aircraft rotax 582 electrical system ? Thank you very much

[@RotacRepair]

I recommend you acquire the “installation manual” for your 582 Rotax. Available free download from rotax-owner.com or flyrotax.com.

Leave the heads off and eliminate the angle issue. Now you can use a standard dial inticator without having to compensate for the anlged spark plug holes. Perfect!

[@RotacRepair]

Yes I could have left the head off, however my procedure is to fully assemble the short block first. Then I pressure test and confirm no leakage of the engine. If I was to leave the heads off to do the timing and then later found a leak somewhere the magneto ignition would be extra time to remove and reinstall. Thanks for your comment.
