Air pressure has always worked for me but I have heard of guys using grease gun pressure...maybe look into that.

I used thin styrofoam pieces to take up that space. Cardboard pieces would probably work ok too.

I was unaware you had found and removed the o-rings. You are correct, you would have certainly have seen the washers if they were there.

You may want to do a little more investigating regarding the washers & o-rings. Almost a certainty they are in place and you missed them...it's easy to do.

I don't measure the 15mm - 17mm....I use a pre-set gauge. Yamaha has a wet level gauge which is easy to make & usable with the carbs on the bike. Wet level check is the final word on your fuel levels.

Why don't you have o rings on the mixture screws?

I measure the air space between the top pf the float and top of the carb body. Factory spec is 15mm - 17mm. With the carb in the upright position, as it is when installed on the bike, the closer the float is to the top of the float chamber...the more fuel in the chamber....hence it becomes...

Vmax likes to run lean, 16mm - 17mm air space is good.

Think you're correct with the intermittent sticking float/needle.

I use Marine Grade Stabil, the blue/green stuff in my generator which sits unused for months and sometimes a year or more with no carb issues whatsoever. I keep the tank topped off.

The VMax 1200 hates to sit unused. Many carbs that come through my shop have a pale green haze on the surfaces below the fuel level. I believe this substance settles out of the fuel with unuse. While it's easy enough to remove from the float chamber surfaces it will accumulate inside the...

Yes, that looks like it.

If it doesn't interfere with your spacing you could probably eliminate the tube, or cap the fittings if you do need the spacers.

Are you running any air pressure in the new set up?

I have never seen a replacement seat that far out of spec....however every one I have measured is .002" - .004" undersize, and I've measured hundreds of them. Polish up your OEM ones and put them back in. As you mentioned, the replacement seats will push back out with very little pressure. I...
