Used it to sync the carbs on my snowmobile also used it to track down some vacuum leaks on my pickup truck. Comes with many hoses and fittings making it very universal.

Me encanto el ajuste para cero de la aguja. Tambien viene con espreas removibles en los manómetro por si quieres ver los pulsos de vacío por cilindro.

For the price and speed of delivery it is worth it and they work just as they should, used on a Yamaha 50hp outboard.

My old car has dual carbs and has not been running well lately and have not been able to determine why. I rebuilt carbs, checked compression, adjusted timing and yet just not right.Well I decided it would be a good idea to check the vacuum. Since I have more than one carb I needed more than one gauge which led me to search and find this nice set.It comes in a metal box. Also the frame that holds the gauges is made of metal too!!!The kit comes with 4 hoses, shut off T,s, and I guess adapters for motorcycle carbs.I was able to hookup this tool and read vacuum.I was bummed to find that my vacuum on the right side has the needle fluctuating widely by 10 inches so I immediately knew the problem is on the right side of the engine and now I will need to check the valves to see if one is too tight. If that is good then I have a bad valve or seat. So yes I am glad I finally know where to go from here.Not fun but needed to know.All in all this gauge set is great for diagnosing problems or just to sync up your carbs.Hope this helps and thanks..

this is a good piece to have available. for the price it's a no brainer.but only good enough to get you into the ballpark, the needle wanders with each rev. it seems to be accurate within about 10. so your not tuning your motogp with it.but to get an old garage find on the road, this will do the trick. when switching cylinders for each gauge to test accuracy, they remained close to the same.i needed one and didn't want to spend hundreds, this is good enough for shade tree.
