SOURCE: How to adjust the carb on a McCulloch super

There is no set adjustment on any blower or chain saw. If it were that simple there would be no need for adjustments. The problem is that most equipment manufactured in the past 10 years can not be adjusted by the user. Carburetors are now equipped with either adjustment limiters which limit the adjustment to less than half a turn or with adjustment screws that require a special tool to make the
adjustment. More than likely you will have to take it to an authorized dealer for those adjustments.

If you do have an adjustable carburetor, then gently close both needles and open each on 1 full turn. This should allow the engine to start and the final adjustments can be made at that point. If it still will not start then open each needle 1/8 to 1/4 turn and try again. If this still does not work then most likely your carburetor needs a good cleaning and a rebuild kit.

Sounds like a fuel problem I would look at getting a new fuel filter. You have the carb set right. That's what I have mine set at.. Good luck

Echo blower isles but dies on acceleration


Assuming the gas filter and carb is working properly then you would need to adjust the high side idle screw on the carb. The newer carbs have a protected head on them and you need a special tool to adjust them. If you look at the adjusting screws on the carb you will see a "L" and "H" the screw next to the "H" is for the high side mixture. If you are not able to make the adjustment then the Echo dealer should be able to do it for you. Hope this helps.

Need to know how to set carb with the two screws. Cutter will sometimes start but cuts out when revved


The 2 screws should be marked by an "H" and an "L" stamped in the carb.

if it cuts out on high, or fast, open the "H" screw 1/4 turn at a time while the engine is running, this should fix it.

What kind of carb does the 76 c10 4x4 come with need to adjust


mcdevito75 here, The fast idle is needed when the engine is cold to make the air and fuel mixture rich to keep the engine running while cold, the carb. choke doew this with a bi-metalic spring in that balck round box on the side of the carb, a screw also hepls keep the choke closed until warm up, this screw can be adjusted tpo control how tight it holds the choke cloesed, here"s how to adjust this screw to slow fast idle speed, Locate on the carb, where the gas pedal connects, have a friend operate the gas pedal with the engine off, once you locate the linkage, you"ll also see 2 screws with springs around them, 1 is for fast idle the other for regular idle, you want the fast idle screw, notice this screw will lay against and Half moon shaped tab, while the other screw lays against a shaft, you need the screw that lays against the half moon shaped tab. Start the engine and step on the gas pedal slightly and relaease, at the screw that lays against this half moon, simply turn it counter clockwise or toward you just 1 2 or 3 turns very slowly, you'll hear the fast idle come down but you don"t want the fast idle to low, listen to the engine very carefully, slow it down just a bit, it should still race though but not out of control. Of course for a full carb, adjustment the shop should handle that., but this info will help.

How to set carborator adjustment on Poulan Wild Thing 2375?


hello,the starting point for adjustment screws is 2 turns out.turn in til lightly seated so as not to damage them. there are 2 or more style carbs used on saw,some have plastic caps that need to be removed(a small metal screw used as a corkscrew or pry off) or you need a special tool -splined.set high spped til runs good and back off an 1/8-1/4 turn so you dont burn it up. fine tune low spped so it accelerates when trigger squeezed and re check high speed adjustment.single screw is for idle spped-raises or lowers-if chain turns while at idle back off screw.

Carb adjustment


Screw both screws right in (don't force them) Then turn each screw out 1 & half turns each OUT. This will get engine running. To fine tune- turn low speed screw out, bit by bit, while idling, till engine revs change, then turn screw in till revs change, the correct setting will be somewhere between the 2 adjustments you just made. Do the same thing to the high speed screw, but with full revs. Good Luck. Stevo..

PoulonPro Leaf Blower will not run properly


the carb has a screen in it it needs to be cleaned out the fuel gets crystalized in the carb when it sits for a while. and if the carb has a high and low on the carb meaning 2 screws on the side of the carb .one is for air and the other is for fuel try this first start it up and give it full throttle and turn the high adjustment till it does something screw it in slowley and or out till it is at full rpm sometimes the adjustment screws do vibrate there way out of adjustment .if it dont work then take the carb apart to clean out the screen
