Been flying my 503 Rotax for 22 and 780 hrs. years. Finally the first inclusive easy to follow and believe video on syncronizing my Bing 54 s Most of the time I have used drill bits to set the syncronization. I see the pencils working much better.
should dual carbs be positioned level with the motor or with level flight attitude? The motor tilts way back on a kolb, you have to tilt the carbs forward about 5 degrees to make them level.
Hello, the .285 inches and .300 inches is the thickness of the pencils on the narrow or flat side. This is to set the distance from the bottom of the slide to the floor of the carburetor opening. Hope this is helpful.
Great video. Hi Again Okay I just looked at BRP Rotax online owners manual site and it says the air screw setting is 1.5 turns out on the Bing 54 carb. That is what mine is so should it be 1 turn out from your experience? And how can I tell which adjustment is correct for my engine? My 582 is a grey head manufactured in Aug 1992 Thank you
Okay my 582 grey head upside down is idling rough. I have already rebuilt the Bing 54 carbs with up to date insides. FYI the side thickness on the carpenter pencils are all different too. I bought some and found out that they are all different widths and thickness. If to narrow they don't cradle very well in the bottom of the carb. But nun the less I did everything as you described and my engine still is idling rough below 2800 rpm. I even used a set of motorcycle vacuum gauges and tried to sync that way too and no difference but couldn't get it to idle down to get a steady vacuum reading. Any suggestions as to what I can look at in order to get it to idle smoothly at 2250 rpm? Thank you so much.
@@RotacRepair yes rough below 3000 rpm and smooth to full throttle. I just pulled the carb’s off and they appear to be clean but I have not cleaned all the passages yet. And I will check the floats for bouncy and adjustment. O rings look good and and jets and needle valves. I have to check the clips. I checked the primer valve and it works good and not leaking extra fuel when running
@@RotacRepair great,where can I get my hands on a voltage regulator for a 503,,I tried looking on line but I'm no good with computers,I'm in nova scotia

Thank you for the kind and positive comment from a very experienced 503 pilot. Happy flying!
or you can just move the throttle so the slide is at the very top and sync them just by feeling the edge, you can feel .001"
That's an ingenious use for a carpenter's pencil! I'm loving your videos.
Thank you and more videos to come!
Most excellent video! I will make good use of this information.
I’m happy to be of assistance
Great video,You should make a video on using the homemade water monometer to fine tune the carbs.
Great idea!
Another great video. Thanks, John.
Your welcome Dan.
Works perfectly. Thank you for sharing.
You’re welcome, happy flying!
I’ve noticed oil drips from the carburetor oil filter after the flight,what could that be ?
Hi, is your 503 operating on premix or oil pump?
That's a real good system
Thank you
I would recommend testing the fuel pressure as your questioning the fuel pump.
should dual carbs be positioned level with the motor or with level flight attitude? The motor tilts way back on a kolb, you have to tilt the carbs forward about 5 degrees to make them level.
I adjust my carbs to be level at flight attitude.
Can you talk about the chock, how fare the lever should move?
Yes, the choke would make a good video topic, all see what I can do about that.
Good morning
Excuse me but I don't speak English.
Could you tell me what the numbers on your pencils correspond to?
I have a Rotax 582 with 390 hours.

Generally I start at 1 turn from all the way gently seated.

I’ll need some additional information if that’s possible. Is you engine equipped with intake silencer kit or K&N oval air filter?
The engine runs rough below 2800 rpm. Does it smooth out past 3000 rpm and run normally to 6000 rpm?
@@RotacRepair inn oval

K&n chrome.
Hi John. Have you ever looked into or done a Bing to Mikuni carb conversion on a 582?
No I haven’t, however could you please share your thoughts as to converting to Mikuni carbs.
Friend uses same principle but uses a Bic Crystal ballpoint (7mm across flats) for his adjustments
Thanks for sharing the Bic tip, I’ll check it out.
Brilliant thank you
Your very welcome
Great info 👍
Thank for the positive comment!
Are you in Canada?
Yes I am, Whitby Ontario about 50 km east of Toronto

I have a Rotax unit in stock, is your regulator blue or silver with fins?
@@RotacRepair I'm going down on Friday,,I will look and get back to you,,do you have a phone number or are you listed with company name?
Very good
