This carburetor fits my Massey Ferguson tractor perfectly! Super cheap and fixed my old carb’s issues. Installed in minutes, fired right up. Tuning was easy with the adjustment screw. Been on a month—survived freezes, fuel lines still soft. Great quality, happy with it!
First time buying these fuel injectors for my John Deere—great quality! O-rings seated perfectly, no leaks or issues since installation. Engine fires strong now, price is awesome. Will absolutely choose this brand again!
This valve is just the thing for switching air/argon on my Primeweld ct520d for switching between plasma cutting and Tig welding. Needed to reverse the handle for clearance, so it's not intuitive which way the valve is open, hence the markings on the box. Left quick release hose is air in. Clear hose on the right is gas in, bottom clear hose goes to the welder, the red hose goes to the gauge on the welder. Used a double male connector to attach the valve to the air dryer, and the setup is sturdy enough to switch the valve one handed.
Exactly as described. Thanks
