I just cleaned my carb and I know for a fact my float is off.
Possibly crooked.

I bought a float gauge and searched the site to see if there was any info on them. There is not, from what I have found. I have included a picture, and have set it to what I think is the right measurement. Or Atleast the mm of what I’ve seen on the net by looking around. If I am wrong, can someone PLEASE mark on the photo where it’s supposed to be? A little help, embarrassing I know.
Just an FYI: the float gauge measures from on TOPof the lip, not at the rubber gasket. It’s on top of that little lip of the carb where the gasket is (where the bowl goes over the carb)...I would just like to make that clear and if that’s confusing, I don’t mean it to be, I’m just trying to get it right lol.
I also plan on buying a clear tube to measure the gas from the nipple. Should it be over or under that seam where it’s usually measured on the carb? Or matching that height? I had read up on some of it, but there was no gauge info, hence this post.

I also was wondering what is a float drop is, how is it measured (if someone could fully explain that to me that would be awesome. I’m learning as I go) and what measurement is it.

And I need to know what angle to put the carb at when adjusting. A straight up angle will help. If you tell me, for example, “oh it’s 45 degrees” I’ll get it in a heart beat but I’ve not seen an actual direct answer. I know it’s “touching the spring but not moving” or what not...but can someone explain that? Or pictures help...a lot! It’s how I learn is by seeing and not reading. I also don’t understand the terms “tang” or just about anything that involves the float besides the float.

I’m just trying to learn and not pay a mechanic $50 to just fix a float. I want to learn mechanics and if you don’t ask, you don’t know.

The only float gauge I've ever used was a ruler.

Tried looking for a standard ruler and apparently only children use them as they’re misshapen for decoration and “fun.” but got some tubing today. I’ll text it when the new jets get here and make adjustments (translation: mangle the thing until it works right because....shrug…) and give it a go.

i just hold the carb upside down and eye ball it. if its level its close enough, im lazy tho.

We have a winner for the worst advice of the week. Congratulations.

Using a jar you don't have to remove the bowl each time you attempt an adjustment.

No. The tube is not used for measuring. It is just suppling fuel to the carburetor.
Fill the jar about 1" from the top with gasoline. Set the carburetor on the jar and let the jar finish filling through the carburetor fuel input nipple. The float needle should shut the fuel off before overflowing the jar. Measure distance from carb base to top of fuel in the jar. You need a jar with an opening the carburetor base will rest on, yet allow the float to move freely.
The pic is of a carburetor off an outboard motor. You can see the float dangling inside the jar.

My wife saves jars for me, so I have a few to chose from. None have labels, so unsure what they are from. The ideal jar will have an opening size to supports all 4 corners of the carb base and large enough to allow the float to move freely.

It's a unique solution. If the jar doesn't fill you bend the tab up and if it over flows you bend the tab down. I like it.

But it's still easier to take a proper measurement. Since I adjusted my first carb at the age of 10 years old I've never once got it wrong.
