starkruzen Posted January 15, 2010 #1 Posted January 15, 2010 I want to tune my carbs and need a vacuum guage. Does any know if I can get one at a local store? Any particular type? Thanks Mark
Eck Posted January 15, 2010 #2 Posted January 15, 2010 I would think you would need (4) of them if I am not mistaken. Your local "Lowes", "Home Depot" or "Ace Hardware", might have what your looking for..
wes0778 Posted January 15, 2010 #3 Posted January 15, 2010 Four would be Ideal, but I use two that I got from Harbor Freight. Think they were about $25.00 US, each. Will eventually buy two more and need to get some kind of valve to restrict the hoses as the needles "bounce" way too much and I have to pinch the hoses to get the needles steady. Yeah, I know $25.00 each for 4 gages I could have bought a "Morgan"... :bang head:
Dave Insley Posted January 15, 2010 #4 Posted January 15, 2010 Our group benefits from the English-made Carbtune II which is available for under $100 and quickly (10 minutes) perfectly balances 1st gen and 2 gen carbs. Yamaha made an error in the procedure for 2nd Gen balalncing which was later corrected. The generations have different procedures. Check your threads for Carbtune. Bilk/Dave Insley
mrich12000 Posted January 15, 2010 #8 Posted January 15, 2010 Hi I made mine from gages I found at Princess auto. cost me @4.00 can each. you will also need fluter valves and they are available from a ford dealer they were used in older smog erg lines. these flowed one way but let the vacuum out slowly. here are some pics of my stack. http://www.princessauto.com/downloads they do ship, and are cheap..
Yammer Dan Posted January 15, 2010 #9 Posted January 15, 2010 I have Mecury Sticks and access to several Carb-Tunes. Question is what other optins do we have to adjust mixture since I still can't find that &@###$ Color-Tune????

I see they're going for $7.99 a piece. I wonder how accurate they are,(+/-). Dial reads 0 to 30 in-Hg. So 0.6 bar = 17.717 989 843 in-Hg [0 °C] = 8.702 264 280 4 psi.

Guest HotMech Posted January 19, 2010 #18 Posted January 19, 2010 I have an old set of "Carb Sticks" surgical glass tubes, dipped in mercury, on a cardboard back with black lines. works great and I've had them for years. got them from and ad in the back of a m/c magazine. go figure.
