I have a Yamaha F50 TLRS .
I just did a thorough cleaning of my carbs by immersing in a gallon of Gunk. I then did all bench adjusting including the static synchronization of carbs---
I am having trouble with the dynamic adjustment of carbs.
The Service Manual says to do this---
And then this---
The vacuums gauge was just purchased at Napa for about 50$. It is a dial type gauge (not a mercury tube).
I am inserting the vacuum gauge in the measuring port----- one port open at a time.
My problem is the vacuum gauge swings wildly thru an arc of about 120 degrees. Is impossible to get an accurate read.
When I sucking on the gauge it reads OK. It is like the measuring ports are huffing AND puffing!
This engine is now almost 15 yrs old and has never had anything done to except winterization.
Please--- any suggestions?
