Setting float levels Wet Method

Hi Folks,
I'm about to embark on a float level adjustment project on a couple of different configurations of carbs. In the past I've just taken a chance that I won't start a fire on my work bench. I'm thinking that I'll rig a temporary fuel tank up high with some sort of cut off valve. I'll have the carbs mounted in various ways over an aluminum catch tray. In case things really get out of hand I'll have a fire extinguisher ready but I'd really prefer to not contaminate everything with extinguisher powder. What would you think of a custom fabricated metal lid or cover that I could just put over the whole thing in case of a fire?

That would work, but isn't there a less flammable option to gasoline?

Mineral spirits are les s volitle and should still work.

I think the safest option would be a calibration fluid like Viscor. I think it sells for around $60 per gallon, but it is reusable and way cheaper and safer than a blast cabinet :ohmy:

Thing's float because they weigh less than the liquid it's it's floating in you change the liquid the float weigh need to be heavier
or lighter depending on the weigh of the fluid to keep the level the same.

I use gasoline, Just keep all electrical equipment away of any drip and splash. A catch pan sounds like a good idea so please share a photo of your setup when you get that far.

True, and that is the point of calibration fluid.

As long as you have good ventilation you shouldn't have any problems.

I usually have a thin hose that runs down to a container under the work bench, that I attach to the float bowls and drain them one after the other before I open up the bowls again.
All fuel ends up in the container and there is usually no spill.

Can set correct fuel level in just one carb using the clear tube test with gasoline.

Then use another fluid of choice -- such as odorless mineral spirits, common household rubbing alcohol (my fave), or even tap water -- in the same known "correct" carb to determine the level inside the clear tube using the chosen alternate fluid (which has a different specific gravity), which level will be either somewhat higher or lower depending on whether it's specific gravity is lower or higher than the specific gravity of gasoline.

And make note of the level inside the clear tube produced by the alternative fluid, which then is the "within spec" level for the alternate fluid which will produce the correct "within spec" level when using gasoline.

Having one known correctly adjusted carb, the remaining clear tube testing and adjusting can be done inside sitting comfortably at the kitchen table without any danger of fire or gasoline fume inhalation or the obnoxious stinkin' odor of gasoline.

Good Fortune!

^That. Exactly.^

We tried all manner of (relatively) benign liquids as alternatives to gasoline where we were searching for ways to do carbs in our basement workshop during winter months. A standing pilot light in the water heater dissuades us from using gasoline.

We tried:
distilled water
kerosene
antifreeze
rubbing alcohol
turpentine

None matched gasoline in a wet test.

Never heard of "calibration fluid".Sounds interesting. Link?

Jeez, what are we all fairies here! here's what to do, no naked flames, no electrical appliances running, no smoking, keep well ventilated, do the job, ride the bike.:huh:

Thanks folks!
I'm going to try just turning off as many electrical circuits as I can. I've got a good exhaust system which I'll crank up. I'm thinking that I can fold and spot weld a box/cover to just set over the whole thing if the worst happens. I'll post some picks as I get closer.

I think I've found a good multi use product that will serve to smother any fire I might start.
How about a welding blanket?
