i installed carburetor no ajustment needed engine running great on thirty year snow blower in michigan i think iwould check fuel lines i hope it works out for you Doyle

I bought one of these carbs, bolted it on and it has worked great. Didn't make one adjustment. Sounds to me like you have a issue with fuel maybe getting to the carb. Normally what was thought to be too much fuel ends up being the exact opposite. Try taking the gas cap off and starting the machine. Maybe vapor lock? Check fuel filter if there is one, that it is not clogged. Collapsed fuel line? Is the bowl on the carb full of gas when the machine shuts off? Oh and to answer your question, the screw is most likely a idle air screw that can be adjusted to set idle speeds on the carb.

Check the fuel line to make sure there are no cracks etc. Also, the bowl of the carb has a float valve and might have come off during shipping. Check that.

the carburetor should be fine is it comes from the factory it may be the governor which is something someone might have adjust at the snow blower shop

Installed new carburetor turned on gas and started on 2 nd pull. No adjustment needed. Did clean gas tank. Had been setting over 2 years. You could possibly have contaminated fuel. Mine worked great

Have you tried with the choke on? Carburetor might have dust - you can never be sure how long it has been on the shelf. Mine was night starting this season so I got the Carburetor cleaned in preparation for the storm.

There may be an easy solution to your problem as I discovered the second time I used my Generac. I kept starting the engine, and it would run very rough, and as soon as I closed the choke the engine would stall. I finally figured out that I had the fuel flow switch turned off, and as soon as I moved the fuel lever to the open position, my problem was solved!! Although I felt extremely foolish, I felt it was important to share with others. The fuel lever is not well marked, and I did not notice that I had left it closed.

A heavy fuel smell coming from your carburetor may indicate that you have leak somewhere in the carb body itself.

Sounds like fuel starvation, my saw was terrible when I first got it, very hard to start. Adjust the carb. Runs like a champ now.

I had quite a hard time with mine. I took it into a professional mechanic who had to adjust it. Seemed to run fine after that. I haven't used it in months now so there's really no telling if it's still going to work. The mechanic I took it to said you need to find gasoline without ethanol and it shouldn't be more than a month old. Otherwise it wont start or run right. Of course I'm on my second saw now. The first went to hell after about 5 hours of use. Sorry, I don't trust this thing very much. Caused me lots of frustration.

I installed my new carburetor and made "no" adjustments. It has been in service for several months and has not required any adjustment. I am very happy with this product.

I've had no problem with mine at all. This includes all points where the gas line and carburetor might leak. Certainly if you strain the gas line or damage the unit, there may be a problem. I always would suggest that the line is shut off and carburetor drained out by running to minimize any possible leaks and start up problems when the unit is put into storage. the units that were a problem were generally smaller than this one, although I still think 'operator error' may have been a significant part of the problem.

I sold my Poulan pole saw. The mixture was either 32 to 1 or 40 to 1. I have changed to 32 to 1 on everything. I had a couple of 2 cycle engines to burn up. Part of it was due to running too lean on the gas mixture. Some of these new carbsrequired a special tool to adjust the carb. .. Doug / Texas

Ned,I'm no mechanic, but I can tell you what happened to mine. Same problem, very hard to start and then to keep running. In a nutshell, I was using regular gasoline which in a few short months caused an air leak by eating into the seal on the carberator plate cover. You might want to check and see if you have any leakage on the bottom of the carb plate. I replaced the gasket and started using Alcohol free gasoline (which the literature says to use) and have had no futher problems. Starts easy, runs great, without the constant priming. BTW - I found that Dealers will not cover any gasoline areas under warranty. Ned,I'm no mechanic, but I can tell you what happened to mine. Same problem, very hard to start and then to keep running.

I have had no problem starting the chain saw. I have started it at least 100 times. I have had a sometime problem while the saw is warming up that at full throttle it stops running. However after a while it will run at full throttle. Just to make sure it is a carburetor issue you may want to read the starting instructions again. Make sure you pump the primer bulb about 5 or 6 times times. Pull the choke all the way out as far as it will go. That will activated the start button. Next pull the cord 5 times. After that push the choke half way in. Pull the cord until it starts. Once it starts let it warm up by pulling the throttle all the way for a few seconds backing it full and partial throttle for about 30 seconds. Hope this helps and your issue is pumping it with gas, full throttle, half throttle and warm up. I am sorry but I have no knowledge about the carburetor.

Mine did not but there's must much "adjustment/setting" to be done inside a carb. Once rebuilt, the stems that are used to adjust flow would be set according to the manual that came with the original equipment. However, I prefer to just get it running and then adjust the gas & air flow... which are done outside the carb... until it's running smoothly.

I tucked the wires back behind air cleaner and a mechanic friend of mine told me to do the same with the hoses. The larger one goes to a canister mounted on the bottom of the bike (smog thing I believe) and the smaller one goes to the carb on my bike. He said I may need to adjust the jets but I haven't yet, seems to run great. However, it does tend to backfire now when it's really cold. I allow for more time warming it up. I'm no mechanic and can't swear this is the best methodology but, it's worked great for me the past 3-4 months. Anybody else have a better suggestion, please let us all know.

Most small engines are set to run very LEAN from the factory(for emissions). There are two, recessed, carberator adjustment screws. One is for high speed, one is for low speed. Turning the low speed screw(usually an "L next to it, also located CLOSEST TO THE ENGINE) counter clockiwise just a hair, richens up the mixture and allows it to idle again. Should the engine not run good at high speed, misfiring, etc, adjusting the HS screw will help as well(again, usually richening it)..

The regulator is probably bad. I had this same problem on this model. Had to replace the grill. Not sure why it does, but something happens and it does not let enough gas through to heat, or, no gas flow at all. I tried turning the adjuster knob slowly from low to hi and back, several times. No go.
