Yamaha 150 TXRC carb float question

[TownsendsFJR1300]

With the gaskets installed, the floats WERE SET correctly. At least two needles/seats were leaking.

And, if you think about it, once the carb is closed up, the gasket has the bowl slightly farther away from the body-makes sense..

I can show several instances in a GENUINE Yamaha motorcycle shop manual where it was flat wrong. IE, when checking valve lash(shim and bucket), Yamaha has you turning the engine BACKWARDS!!!

Psalm 99, I am lost, I hope you know what measurement with the gasket on?

because I don't have the manual , I can tell you that its best to set the float with the gasket in place.
that way you cannot mix up the floats after removing them to install the gasket.

some things are simply obvious.
or should be.

My thoughts are that
Manuals gave been printed with wrong info before and will be again in the future.
My Yamaha service manual gave the wrong steps for link and syncing.

When someone with a lot of experience tells me something different than the manual I would tend to believe him

Then why does'nt he simply say the manual is incorrect, that that is why we should trust him?

trust me, set the floats with the gasket in place.

What's wrong with the setting to his manual (without gasket) after he fixes the leaking needle and seat?

I have the same engine and its runs great at all speeds except idle...

Is there anyway to pull the jet out and clean and re install without pulling the carbs off all together?

And if so can someone please send me in the right direction and where that idle jet is located on the carb?

I have done motorcycle carbs but they are always under the float and it had to be taken apart..

Thanks

When asked if I wanted a broke ass, or what? I said I wanted the "or what" thinking it could not be worse than a broke ass.

Thanks for the pic, seems we have the same manual. I've also heard that the float should be about level as it is shown in the pic. All mine are were pretty level after setting for the 0.63" setting. Removed all three carbs. Turned each carb upside-down (seal orifice by gravity) and put Mityvac on fuel inlet tube. #1 carb held pressure fine (10 psi). #2 and #3 held no pressure at all. Worked on #3 first: Cleaned needle valves and seats (just wiped clean) and inspected needle points & seats with magnifying glass. Looked fine and reassembled. Held pressure @10 psig fine. Will do same to #2 and, if correctable, replace carbs and try again. Weird thing: #2 initially held pressure but after moving it a bit before opening it up, it totally failed. Find out more when I open it up. - Al

Actually, my Yamaha manual for this engine is very specific. Page 4-18: 'Measure float height (a) without the gasket'. Sure appreciate your comments. - Al
