Carburetor flow test measurement beaker
I have made a flow test stand for carburetor jet. I know someone on this site can tell me where and what size beaker in measurements to buy.
Thanks, Gary |

Re: Carburetor flow test measurement beaker
You do not need a beaker. Get a gram scale. 1 gram of water is real close to 1 cc.

Re: Carburetor flow test measurement beaker
I prefer Bob’s gram scale idea. If you are fixed on some kind of volumetric device, try a shop that sells wine and beer making supples sand ask for a graduated cylinder.

Re: Carburetor flow test measurement beaker
Gary, you need something that we used to use in high school chemistry class called a 100 ml Graduated Cylinder. They make them in plastic now (don't break so easily). When you measure a jet, measure it 3 times and average the results.
Here's an example from Amazon for $10: https://www.amazon.com/100ml-Plastic.../dp/B0728C224F

cc = cubic centimeter ml = milliliter gr = gram For your purposes 1 cc = 1 ml = 1 gram Many of the jets flow more than 100 ml per minute. A 100 ml graduated cylinder would not hold 1 minutes of water for some jets. You could measure for 30 or even 15 seconds and multiply the number by 2 or 4. I found that a gram scale is more accurate, easier to read and easier to use. Here is a link to one on ebay; https://www.ebay.com/itm/18607305921...Bk9SR_rZ_o7gYg bob |

Re: Carburetor flow test measurement beaker
If you want accuracy then go with gravimetric measurement. The problem with vomumetric measurement is that it is reliant on the variability of human line of sight, which can vary from one human to another and at different episodes of measurement.
The use of a large volume beaker amplifies the variation. |

Re: Carburetor flow test measurement beaker
I have been using the 100ml Graduated Cylinder (as Jim Cannon stated} for measuring the idle jets and use the 250ml (also available for about $11 from Amazon) to measuring the other jets.

Re: Carburetor flow test measurement beaker
Why is flow tested better than just measuring the actual size of the jet?

There is more controlling the flow through a jet than just the diameter at the smallest point. Flow testing gives you the total picture.
