Where do you get these lean out valves and how are they plumbed in?



A lean out valve is the same as a cut off valve,you can buy them at Home depot,Lowes or Marvins most any hardware store.They are used for both water & gas and come in all sizes so you will have no problem finding one the size of your fuel line,you just splice it into your fuel line close to the carb.and when finish measure to see how long of a push pull cable you will need and go to the boat place and you can find them in most any length you need.I like the Morse cable best its more heavy duty,or you might could find a choke cable at Napa or Car Quest.When you get the cut off valve in your fuel line & a cable to open & close it,when you crank you engine you just close the valve(reducing the flow of the fuel) about 1/2 - 3/4 closed(close as much as possible with out stalling the engine) to warm the engine.Before I cut my engine off after making a pass or just warming it up I will lean it out with the barrel valve till it brings the idle up and then turn the engine off.



Thats why I like to induce the vac leak to lean it down..
its cheaper and easier to do the vac side.. no cable
and you dont have to mess with the fuel line.. hook
up a hose on the intake and run the hose inside to
a ball valve... I never did the one last step of putting
a needle valve on the ball valve so I could flip the
ball valve full open and the needle valve controlled
the leak rate... that just makes it super easy
