I think I hit the send button before I got my mind in gear.. One gauge

won't work as I described it.. One gauge should work other wise.. one

side at a time. Watch the tach.   Herb 




	


Herb,



There are differential air gages that show zero at center scale.  They are a 

little pricey.  The advantage is that only one gage would be required, and 

you do not have to worry about accuracy between two gages.  



Magnehelic makes them.

   Yep. Used them in the computer industry.. 

  My thought that we could use one , teed off of both carbs would not

work.. obviously one could work on an engine at any stable rpm.. Home

made water manometer also.. Herb

| You need two gages because you need to compare the two at the same 

time so you can set the needles to the same on both.

Roger:



What does the above mean?



I don't recall "setting the needles"???

Hi John,



Needles were in reference the needles on the gages.

I just meant that the needles on each gage should be set so they are the same. i.e. When you have 5 on one gage you adjust the other carb so the needle on that gage is 5 or what ever the reading maybe on each gage. Just get them set the same.. syncing the carbs.

Roger:



Thanks.  I was confused.



My line of thinking was more, setting the carbs and reading the 

gauges.

Gang,



Ronnie Smith of SMLA told me at sun-n-fun he was switching to a "one" guage set up and used a valve to switch from one side to the other to eliminate the differance in two or more guages.

Paul:



I like that idea.



Would like it even better if Rotax could get a fuel injection supplier 

and eliminate the need for balancing dual carbs.
