I used to think it was 3- Half turns. But just now discovered on a Poulin Pro, about 1-year old, this was to much. Flooded. Went with, screwing all the way in, and then backing both H and L out just 1-full turn (2-Halves). Perfect. From older models of 2-stroke motors, if, when you pull trigger, there is a lag in acceleration, then open the L little more, till lag is gone. Then at wide open, turn H in little till motor is at it highest RPM (or out, which ever makes it fastest), then back out the H about 1/4 turn. You are finding its most lean point (highest RPM) but, you want to run it slightly rich for most horse power when motor loaded i.e. cutting.

Wont idle

Make sure your spark plug is not fouled and the gap is correct, also air filter is properly cleaned. If it still wont idle, locate the idle adjustment on the carb. There are 2 screw type adjustments there, one is the idle/air screw and the other is idle adjustment which is the one you want. Start the bike and up, slowly turn the idle adj. Inward like tightening a bolt, periodically give the engine a slight rev and let it idle.down. Do this until you reach the desired rpm you want to idle at and your finished

Tk carb ? sthil trimmer has 3 adj screws ,how do you adj?

One adjustment screw (probably Phillips-head) is the Idle speed adjustment screw. Turn it in, to increase idle speed (it moves the throttle plate)...turn it out to slow idle speed down. The other 2 screws are the Low mixture screw and the High mixture screw. The L screw is closest to the engine and is used to adjust the engine at IDLE. The H mixture screw is to be adjusted when the engine is at wide-open throttle to get the proper RPM's....not too little and not too much. Here is a tutorial by Zama carburetor reiterating what I have just told you and HOW to go about your adjustment.

Need to adjust my honda shadow 500 vt carburator's fuel/air mixture

start by synchronizing your throttle plates. Honda calls the next step the "idle drop procedure". u need to know if you have fuel adj. screws or air adj. screws. fuel screws will be on engine side of carb slide, air screws will be on airbox side of carb slide. start leaning out mixture, (turn in fuel screw, turn out air screw. idle will increase so keep adjusting idle back to spec.after each turn if needed. Adjust about 1/4 to 1/2 turn at a time on each carb until there is no change in idle, then richen up mixture by one half turn. If u sync throttle plates first then follow this procedure, there should be no hesitation when you "blip" the throttle, and after revving it should return to idle smooth,

Should b 2 screws on side of carb. One is low speed adj and one is high speed adjust. Turn screws all the way in until they bottom, not too tight--turn them out 1 1/2 turns. Start saw and adjust the idle screw by turning in until it starts to sputter and turn out until is idles smooth same for hight speed only adjust at high speed

My john deere 1600 weed trimmer starts fine cold, then runs on high speed for several minutes then dies .Then will not start.I cleaned spark plug, checked proper oil/fuel mix, cleaned air filter,tightened...

Your fuel low fuel high adj on carb arent set right. one is for idle and low running while other is for high rev. Getting these set just right is very tricky and takes some time doing it to become good,Im starting you off on a crash course,Im not gauranteeing anything but here it goes. LOcate the two fuel adj. screws on carb,if they have plastic caps on top remove them with needle nose pliers so the screws themselves are exposed. Next,I want you to take a screw driver and turn both in all the way till they stop. Now take and turn each one out counter clockwise three full revolutions. Now start it to see if theres any improvement. (Note: further adj. may be required you may have to consult an expert to have it be done for you if you cant get it).
