carb syncing with a manometer

halfway down the page...... Slack-tube manometer

 

could I use two-stroke oil and hook the tubes to where the balance tube usually hooks in......

Don't see why it wouldn't work, still have to get some kind of adapter for crossover holes. I would use colored water rather than oil. Thinner viscosity would react to changes eisier. JMHO, your results may vary .

I was going to use two-stoke oil in case the carbs were way out of sync I don't want water sucked in my motor...... ATF is probably a little thinner I could use that.....

 

I think I will try it...

I could be wrong but I believe those are for a butterfly throttle body and run off a vacuum port.

Just do it by eye and feel. Really simple, once u start messing with it, youll know where they need to go.

butterfly or slide valve it still has vacuum behind the carburetor and you can measure it at the transfer tube ports..... a vacuum port just gives you manifold vacuum unless its a ported vacuum port like you hook a distributer up to that has no vacuum at idle....

I built an oil manometer for about 5 dollars to balance my lectrons and throttle bodies now. Using some atf for the measuring fluid worked fine. I would not recommend using water because of its low density. People have said the manometer is almost 50 times more sensitive by using oil instead of mercury. Don't know if it's true, but it works well.
