homemade manometers

[jr_2431]

Any suggestion on what is the easiest/well designed homemade manometer? Found some cool ones just looking for suggestions or do people really not use them?

I've got a Morgan Carbtune II but there's nothing wrong with using a DIY setup. It's just not as convenient since you have to keep moving connections.

I just wasn't sure if it was a "Suggested" way to do it. so I was just curious on if I were to go with the motion pro or a DIY type if it really mattered as long as it worked? They do have some pretty neat types. Maybe Ill go DIY type just for the "What the **** is this!?" factor in the garage! Lol

Yes please do, I Have a few Ideas, but any help would be much appreciated. What type of liquid/chemical you use?

Also What diameter tube did you use? and any restricters?

I used some left over oil no restrictors just used 4 6ft lengths of clear tube i cant remember the exact diameter of the tubing but i think it was either 8mm or 12mm ill check it out tomorrow arvo for you the photo will explain all

I made a similar one to this. I used some old Starbucks Frap bottles, stoppers, vinyl tubing and used motor oil. One tip: put something in the fluid that will help you tell which direction it is going. Luckily the sedement in the oil helped me out. I was only able to sync two carbs at a time, but it only took 5 mins for all four.

+1, I used ATF but any kind of oil would work. The red ATF allowed me to see the tiny air bubbles and see which direction it was going.

5 mins isnt bad, how did you do that? did you sync two on one side, two on the other side, then the two middle ones together?

The procedure is:

Sync carbs 3+4
Sync carbs 1+2
Sync carbs (1,2) + (3,4)

All at 1800 RPM. If it won't stay at 1800 RPM, adjust the idle while you sync.
