Thank you for this. I particularly enjoy how you ASK rather than tell, while saying please, to Stefan each time. Such a small thing that really does improve 'work' conditions. Again, thanks for the vid, very easy to follow and concise enough for results.
6:30 another indication that your needle is too lean is once you start it, the RPMs from idle start to creep up by 100-300 RPM. You can hear the motor idle at 6:30 and then slowly creep up a bit, even before the throttle is touched. This is another great indicator that you've leaned out your low needle just a bit too much and you need to open it up just a minute or two. This is a great video on carb tuning!
Thank you for taking the time to put this together. Looking forward to the trouble shooting videos ( midrange has always been a hard one for me to adjust). I like the fact that you show when its outside of normal performance and how it sounds and reacts. Perfect.
I have to say having my engine fine tuned by Stefan in Iceland was the best. Starts on second pull, no harsh knocking and smooth linear throttle. Takes a bit of practice but it’s a delight when done right. Plus you get that sweet feeling of security knowing that your engine won’t die down on you over that glacier or river. Thanks Miro and Stefan fir another great video. 🙏🏻
i have a new Moster 185 Parajet Maverick and was very grateful for this step-by-step tutorial. I have an issue regarding steady state at 6000 rpm where the engine gets to 5800 rpm and surges to 6800 rpm. Thank you so much for helping me better understand how to tune this motor
I own a Parajet with a Moster 185 carburetor and have not done any adjustments since I purchased the motor from Parajet. It was running a bit rough and this video was all I needed to get my motor running perfectly once more. Great content, thanks so much sharing with the Paramotor community. Cheers...
Did you mention that the engine has to be hot before adjusting. If you try to adjust a cold engine it will run too rich when its hot. A perfectly tuned engine will bog a little down low when cold.
@@tubeyou1906 oh did he ? I watched back again but must have missed I. I only left the comment because I didn't want others that were not mechanically inclined to think that its a cold engine.
Worth noting: if you find yourself in the need of readjusting the carb before every flight, check your popoff pressure - if it's too low, your carb will be super-sensitive to weather conditions
Thank you so much, Miroslav for this fantastic video (and the others in this series)! It's a joy to tune my Moster 185 since I have watched it. I guess, it is a regular task to fine-tune the carburetor at changing (at this time: cooling) temperature. Is it true?
great video!!!! Now the high needle and how to low consumption. Mine is waisting 7 liters per hour. L needle les than 1/4 and H needle few minutes closed. Engine 3hours old
Help! Very good vids thanks. So my question, I have atom 80. My seller put in a recall piece in carb and since then it runs horrible, it stops for no reason. I took it back to him, we retuned the carb like in your vid. Air/gas ratio. My issue is the idle, it turns so slow, 1600-1700 should be 1800-2000 rpm. All I need to do is adjust the idle pin, but it’s to its max, it won’t screw more. What can I do. Seems that recall piece messed up my atom 80. It worked so great before. Only one season, 25 hours. Thanks
One thing you should add as a caption: don't use any significant force when closing the L screw all the way in, or otherwise you'll damage the carb seat and this will be irrepairable
Interesting that you set your idle screw to be 2400, I was always under the impression that it needed to be at 1800, but I never liked the rough idle at that speed.
Can you do exactly the same with your ATOM ? Thank you!!! Can you manage the HIGH needle please, because it is possible that in any time we will need to adjust it...
Hey Guys! Question.... It seems the fuel line is getting air bubbles in it post fuel bulb. Is this normal? It is a brand-new unit and I had them send out a new one however the problem still exists with the replacement. Another question... Should the engine sort of surge up around 5500-6000rpm? Almost like you've hit boost as if it were turbocharged? It's quite abrupt and makes me think something is up. Have followed the tuning procedure many times and cannot get this issue to go away. Thanks!
Can yo please be more clear on the amount to open the idle neddle from scratch? You say that from a totaly closed position you counterclockwise 20 minutes. But I have read in the manual 1/4 and I thought that means one complette turn plus 1/4. So, can you please show us the exact amount to open feom scratch? I understand that 20minutes is almost the half of 1 complette turn. Is that the correct interpretation?
the tab connected to the high jet . has fallen off.how do I double-check.is there a set setting? screw the jut in then how many turns out?? high jet needle.
@@SCOUTaviation Thanks. I have the MY20 Atom 80 but the Maverick manual says different settings compared to the Moster (Low screw 22 minutes and High screw 60 minutes). I'm mainly asking can you use this method of leaning out until blipping is not responsive on any engine like an Atom 80 or Top 80? And do you prefer this method compared to checking the plug colour?
@@turkeyphant yes you are correct. I thought you are referring to the low needle as it is the same for Moster and Atom. Moster manual says 15-20 minutes. Atom says 22. The procedure for tuning low needle would be the same for both engines but i do not have that much experience with Atom 80 low needle tuning. Simply because I never had the need to tune the Atom 80. It was always running perfect. The Moster I tune more often. The spark plug color should be checked after a minute or two of full power and that is mostly affected by high needle. Summary: I adjust the low needle by idling behaviour and I adjust the high needle by max RPM and spark plug color. There is a difference in high needle. Moster 69-75 minutes, Atom 60 minutes. Sealed.
I’m pretty sure those aren’t minute marks. That’s just a 3/8” flat head socket that happens to have knurls in a manner similar to how minutes would be set up. The knurls are more for grip but it definitely helps visualization as it has to be close 👍
If I were to do this procedure, my Moster 185 would become impossible to start after 4-5 starts, after it becomes warm. What would cause it to be so difficult to start when warm?
This pro0cedure should be done on a warm engine. Your case is really unusual. Usually it is a lot easier to start an engine warm. I do not have an advice for you now. I wish I could try the engine myself
Thank you for this. I particularly enjoy how you ASK rather than tell, while saying please, to Stefan each time. Such a small thing that really does improve 'work' conditions. Again, thanks for the vid, very easy to follow and concise enough for results.
by far the best moster 185 carb tuning video, thanks
Thanks for this. This is the first well-done guide for this process I have seen yet. Very helpful!

This is simply the best guide I can find on this topic on TH-cam. Thank you, this was very helpful to me.
Very well done. I tried this technique and my engine running even better. Thanks mate!

that sounds like a combination of rich low screw and lean high screw.

This video increases the value of my Scout... I haven't had to do any work on it yet but when I do these videos will be invaluable.
Thank you that was the last little bit of info I needed to get it running perfect.
Nice video with up close adjustments
Excellent tutorial! Wish I knew this when I was younger! Many Mikuni carbs come to mind... Lol
So thankful for this! I was turning 1 and 1/2 turns out. Lol.. Now I understand
Very informative for me as newbie to understanding the settings of the sweet spot, Thanks for the effort chaps.
Certainly going through this procedure Miro.. excellent
Exactly the guide I needed; very well and clearly explained... thank you.
Fantastic Video. Especially for a noob and mechanically declined person like myself !!
Did you mention that the engine has to be hot before adjusting. If you try to adjust a cold engine it will run too rich when its hot. A perfectly tuned engine will bog a little down low when cold.
He definitely mentioned a warm engine in the summary at the end.
@@tubeyou1906 oh did he ? I watched back again but must have missed I. I only left the comment because I didn't want others that were not mechanically inclined to think that its a cold engine.
Once my engine is hot, it's nearly impossible to start.
Worth noting: if you find yourself in the need of readjusting the carb before every flight, check your popoff pressure - if it's too low, your carb will be super-sensitive to weather conditions
How would we check pop off pressure?
Very good explanation, thanks very much.
Glad it was helpful!

Thanks for video. Could you please tell where the helmet comming from?
Great video, Very informative not only for Vitorazzi motors. Thank you!.
Any guidance for the Walbro WG8?

Thank you for a great video.
Please continue with these Videos. I hope Vittorazi pays you for that as their information are very weak!

Nice tuto, but is it also applicable for other carbarators ?
Hello, can you tell me the optimal working temperature measured in the cylinder head?
What's the name of the visor used on that helmet?
Thx it helped me
Hey Guys! Question....

Great video! Thanks!!!
Great video an explanation!
you can show the spark plug color with your settings?
can I ask where you got your headset from, and does it include Bluetooth? I'd like to be able to answer calls and listen to music while flying.
Can yo please be more clear on the amount to open the idle neddle from scratch? You say that from a totaly closed position you counterclockwise 20 minutes. But I have read in the manual 1/4 and I thought that means one complette turn plus 1/4.
So, can you please show us the exact amount to open feom scratch?

the tab connected to the high jet . has fallen off.how do I double-check.is there a set setting? screw the jut in then how many turns out?? high jet needle.
Is it the same process for the Atom 80?
The new version of atom 80 has the same carburettor. Only 2018 version has a different one.

I have a new 185 plus, I'm braking it in , but it dies at idle, what do I do? Thanks
NOTE TO SELF: I need to buy that tiny screwdriver with the minute marks on it!... Lol
I’m pretty sure those aren’t minute marks. That’s just a 3/8” flat head socket that happens to have knurls in a manner similar to how minutes would be set up. The knurls are more for grip but it definitely helps visualization as it has to be close 👍
Uh, maybe just take YOURS to a technician. Those aint minute marks and thats a basic 3/8" drive screwdriver socket. lol

Why my moster my20 max rpm is 8000? After and before this configuration. Not ~8600. Its normal?
Thanks need that
I have missing in my engine at 5000 rpm some time at 6000 rpm ?
1/3 of a turn is 120 degrees (1/3 of 360, 360 degrees being one full turn).
1 minute is 1/60 of a degree, or am I missing something here?
One minute we meant 1/60 of a full turn
