Hello! I thought my engine was from 1991, so I ordered a jet air bleed from the boat net but when I got it, it was not the same sise. contacted yamaha and gave them the serial number on the engine, it turned out that the engine is from 1990. Went out on the boat net for ordering this part, but this was not on the exploding diagrams, apparently sels this jet air not separatly, its the same on al the engines from 1990 and backwards. i do not want to buy the whole carburetor just because a jet air bleed is poor. my carb is perfect condition except for this part. Maybe you have this in the right sise for me??? . Sincerely Bjorn

pics of my jet

i sendig picks of my jet air bleed , there is no part number for this, but it placed on the same place that jet 61A-1492G-58-00 is placed. On the top of the carb, under the stailessteelplate.

Take pic of where it came from on the carb and post
never mind, it is listed as 61A-1492G-58-00 JET,MAIN AIR BLEED
was there a number on the face of the jet?

the rest of the world calls it a bowl vent.
it regulates air pressure in the bowl at higher speeds.
as long as the inside diameter has not been modified and the threads are ok its good.
and it wont affect most runnig conditions.
rest of the world calls it a backdrag design carb.
the pilot air jets are located in the airhorn just in front of the venturi.
the pilot fuel jet is in the fuel bowl.
not to be confused with the mai fuel jet.
air fuel ratio is fixed at idle by the pilot air and fuel jets and at high speeds by the main air and main fuel jetting.

Do you need one or are you just asking because you are curious?

Froggy last posted in March of last year. He seems to have hopped out of here.

If you are still interested. I used KEIHIN ROUND JETS 99101-393 for my carb. Just grind the top and made a notch for the screwdriver. It worked for me.
