Any time you see a dot on a phillips screw such as the ones on these carburetors they are what’s called jis (Japanese industrial standard) screws. Regular phillips bits do not fit and will round them out easily but the appropriate jis bit or screwdriver bites into the screw very well and will not cam out, no need for breaking loose with a flathead
@@srt5321 yes 2 on carburetors. I have seen 1 and 3 elsewhere though, usually on electronics and motorcycles. 2 is certainly most common 👍 jis works well on normal phillips as well but not the other way around
I have cleaned carbs that are super similar maybe the same carbs for yamaha 50 horse 2 stroke. I used a air compressor to dry/ clear out the power tune spray...I lost one of the super tiny clips for the needle... couldn't find it anywhere. I had to order a new one and it cost me $20 after shipping and week of waiting. Now I don't use air compressor anymore and they clean just fine with just the spray. I love your videos thanks for the in depth explanation of how carbs work!
Hey I’m a marine mechanic here in Louisiana I’ve rebuilt a lot of these carbs but I still appreciate you taking time to go over the cold start passages long time subscriber keep up the good work
hello! I have a Yamaha 90 hp two-stroke engine, and after being in idle for a few minutes it stops. Do you know where the problem could come from? what part of the carburetor? thanks for your time
Thank you so much for all the great videos . I have a 1989 Yamaha 150Prov. Every time I come back from the lake, I drained the carburetor bowls by unscrew the drain screw underneath. If I don’t do this, the ethanol and corrosion buildup will mess up the carburetor since I don’t use the boat that often. If I let the fuel sit in the carburetor for two weeks, I will have hard time with the carburetor idling and running properly. If I don’t drain, I would have to take everything apart and clean the carburetor every year. My question is that is there a better way? Am I doing more harm to the carburetor by wearing out the screws? Thank you

You are going to put MMI out of business ! I wish TH-cam had been a thing to the point that it has grown now when I went down there and spent 20K a year of my life and eventually gained an ex wife from it ! I was there in 2003-04. I never worked for a dealer, they wouldn't pay enough to support a family. I had to hang my shingle and get after it as soon as I got home, been rolling ever since.

These are crazy expensive on Amazon. Do you know which size generally fits carburetors? I’m guessing +2?

Well that’s the best carb cleaning and function video I’ve ever seen. Thank you thank you! Most people do not explain it in detail like that. 👏👏👏👏👏👏
Thank you!

Thank you Troy ;)
Im assuming the "electronic enrichener" is the newer replacement for the old manual choke. It is used for cold start fuel enrichment. Right?
I love my Johnson. Throttle plates on the motor, carbs come off with 4 bolts, no hoses, or linkages.
Really enjoy your videos!
Loving the daily uploads!
It's convinced me having my dealer clean them if necessary is worth the headache
Lol :)
the needle extends,when powered,not retracts, to close off the hole.

Use fuel stabilizer
I have used fuel stabilizer, but it does not work . Was the topic answered in the podcast? Because I couldn’t find it. Thank you
Hey Aaron…I’m living close to you! I need contact to you to do a work! How?
Thanks for the video!
Why do outboards have one carb per cylinder and not a single carb and intake manifold?
Some outboards do some don't. I'm working on a mercury right now that as 1 carb that feeds 2 cylinders.
You forgot the part where carb cleaner exits random gallery and goes in your eye.
You ain’t lying
Lol and people think it's weird I'm always wearing sunglasses lol been down that road before lol
How many hours on this before carb clean?
No idea
Great explanation. What do you recommend for winterizing a carbureted engine?
Just flush and fog the engine and drain the carb bowl :) treat the fuel before flushing and run the treated fuel through the engine
Amazing video.
Thank you!
why contact cleaner and not Carbonator cleaner?
+1 for Aero Kroil...
Stuff is awesome
Lots of holes and squirting...for second I was all confused 😅
