Hi Darrell:
Here's what I was taught.
- Wear hearing protection.
- Start saw.
- Adjust low speed screw... turn in slowly until engine falters, then back out a bit until engine sounds happy.
- Place screw driver in high speed screw, apply full throttle, adjust high speed..... turn in ... rpm shoud increase, ten drop off... back screw out until maximum rpm, then a tiny bit more to make sure the mixture is not too lean.
- Chain saw should now be happy.

Saw starts runs good then when i start cutting it


Hi Jason:
Make and model might help but here's two ideas:
1) Remove muffler and clean it. They can get plugged up with carbon and the saw will run at low RPM but will quit because of excess back pressure when you try to rev it up.
2) Set the high and low speed carb settings. Start the saw then gradually increase engine speed until full throttle. Screw the hi-speed needle in slowly. If RPM immediately drops, back it out until Rpm increases, then starts to drop. Screw back in until peak rpm reached, then starts to drop. Back out to peak, then 1/3 turn more.
Set low speed so engine runs smoothly but chain does not turn.
Hope this helps.

Adjusting the tickover and mixture


The carb is factory set you need to remove carb you will then see two screws one marked L and the other H with a small hacksaw cut a slot across both screws don't worry about cutting into carb body this can't be helped screw both screws fully in then back them off 1 and 1/4 turns this rough sets high and low running start saw set low speed first adjust screw in or out to get best low running then rev saw to max.and adjust max revs do the same as you did with the low speed screw to obtain max revs this should solve your problem.

How do i set the carb on a ryobi


I haven't heard of Ryobi using a carb different to most similar machines which use a small diaphragm-type carb which uses suction impulses from the 2-stroke engine crankcase to lift fuel from the fuel tank into the carb. There is generally one screw which is a throttle stop and two screws which are fuel volume screws; one with a greater influence at low speed and idle and one with greater influence at high speed. The low speed screw does have some influence at high speed and the high speed screw does have some influence over low speed fuel mixture.

The basic settings of the screws should not be lost and if stripping and cleaning the carb each screw should before removing be carefully turned in, counting the turns, until it bottoms so after cleaning it can be returned to its former position.

The amount of adjustment from the position the manufacturer set each screw to would typically be in the order of plus or minus one-eighth of a turn and if adjustment of more than about a quarter-turn is needed it could indicate the carb needs a thorough clean.

Making an adjustment of one screw means adjustment of the other is almost inevitable. The basic requirement is for the machine to work under load efficiently at high speed and it is usually desirable the machine will be capable of idling. Obtaining both is rather a balancing act and will need some patience and time making minor adjustments of each screw and in practice some compromises must be made and if hard work at speed has been achieved it usually doesn't pay to try too hard to achieve a smooth idle.

I have a stihl 025. the carb i had had 1 adjustment the replacement carb has 2 set screws, what should the settings be to get started with


Usually when purchasing a new Carb, they are set very close. No adjustment needed. But if you want to play, turn both the High and Low screws all the way in then turn them bot out about 1.5 turns. that should get it started. The you will need to tweak the High sped and then the low speed and then the Idle

Carb. is clean but will not idle and bogs down when you rev it up. Baja Motorsports 2006 125cc dirt bike


Hi,Twhitesilver and the usual suspects are:
1. Idle speed improperly adjusted.
2. Inlet system air leak.
3. Leaking accelerator pump.
4. Loose low-speed jet.
5. Plugged low-speed jet.
6. Contaminated or plugged low-speed circuit.
7. Enrichner valve is not seated or leaking.

I have a Toro 524 with Tecumseh engine, model 38040 8 0000640. I am rebuilding the carb and would like to know what are basic settings for idle and hi/low speed screws?


The high speed mixture screw is initially set at 1 & 1/2 turns out. Then adjust it to give good acceleration and top speed, while not closing the screw more than you need to. The low speed mixture screw is set at 3/4 of a turn out. Adjust that, to give a smooth idle. The 3rd screw, the idle speed screw, is set to give a low idle speed without stalling.

No power fs66 stihl weedeater


Hi When you cleaned the muffler out did you also clean the carbon out of the port on the cylinder as this can be blocked as well. Also you will have to retune the carby, There should be 2 screws 1 for low speed marked l on the carby body and 1 marked h for high speed to start with they should be set at 1 & 1/2 turns out from closed the low speed you set at an idle and the high speed you set at full throttle. Hope this helps.
