STEP 1 Open the high speed needle valve 2-3/4 turns fully from closed (counterclockwise)
When your closing the high speed needle close it until becomes firm DO NOT overtighten this may damage your engine
STEP 2 start the engine
STEP 3 once you have started the engine turn the high speed needle about 1/8 of a turn at a time until the engine barely runs run the vehicle away from you and back then adjusting the needle.the engine will perform sluggish and will stall every now and then that is normal.
STEP 4 drive the vehicle away from you and back slowy accelerating it up and slowly deaccelrating
STEP 5 After a few minutes of driving it back and forth make sure it is not overheating by putting a drop of water on the cylinder head and watch it boil it if boils away instantly it is running to lean and if it takes 2-3 second to boil it is running rich that is good while running it in. Remember if there is lots of smoke coming out the exhaust then it is running rich but if there is not much coming out it is running lean.
STEP 6 Run the vehicle back and forth until the tank is nearly empty DONT let it run out because it leans out the engine causing it to overheat.
STEP 7 stop the engine and let it cool down for about ten minutes before running the next tank.
you will notice the engine will start to run a lot better after the 3rd or 4th tank.You should only have to run it in 5 tanks.
