You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.

I have a Poulan pro leaf blower. It will not start. I rebuilt the ZAMA carb, have spark and 40 lbs compression. Any ideas on where to go from here?


back to the carby for a check on what you have done
normally it is the diaphragms position or blocked jets
check the quality of fuel ( E-Mix fuels are not good for small engines and the oil you are using ---some engine oils block the jets )

HOW DO YOU ADJUST THE CARBURATOR ON A POULAN P3500 STRING TRIMMER


Due to EPA regs, users are supposed to be restricted from adjusting carbs, but there are special tools provided by the manufacturers for this purpose. Only service techs are supposed to have them. Most carbs have an H and L adjusting needle on them. Some are Zama, some are Walbro and some are imitations of the 2. Some have "splined" heads, some have "Pac-Man" type heads (with small V-cut in them), and some are "D" shaped. With some ingenuity, one can fashion a tool to use to remove some of them. Small aluminum tubing can be forced over a splined head needle and turned. Small jewelers needle-nose pliars also may work.There are sellers that have tools for all these carbs. I would like to refer you to the Zama carburetor adjusting tech page.

Wont run up to speed without choke partially on. Where are the carb. adjustments? Does it requir a special tool/


Probably uses a Zama Or Walbo carb. The mixture screws are factory preset and may or may not have plastic limiters on them. There are tools for adjusting these type carbs or you can fashion one yourself. Most of the screws are of the "splined" variety.Running partially choked is a result of the carb needing adjustment and/or repair (rebuild kit). Like anything else, they require maintenace and installing diaghram or rebuild kit accomplishes this...you can remove and clean the carb and its internals with non-flammable brake cleaner aerosol spray. Don't use high PSI compressed air on it and never soak the carb.

Trying to get my Poulan BVM 200 to start consistently. Need a service manual or help with the carb adjustment screws. Does anyone have a manual or a good description on how to do a carb adjustment?


These machines are typically at the bottom of the food chain when it comes to quality control and workmanship. Many are sold, but many turn to junk. You probably have the splined-head screws typical of a lot of these carbs..a Zama possibly. They have the carb adjusting tool for these for sale on Ebay. There are other home-made ways to loosen and adjust these screws too. Consistent starting probably won't be achieved till after you install a carb diaghram or rebuild kit and replace any old fuel lines and filter. Some of these engines run great and some are lemons.

How to adjust the low and high settings on the carb


With all the new EPA guidlines on emissions there are many new type of carbs.The older type was easy, If its a walbro or zama brand and it has 2 adjustment screws as well as an Idle speed, preset the low and high at 1.25 turns out from set, start the saw, run it to full throttle,adjust the high speed needle counter clockwise untill you hear the engine start to flutter. You want to year the flutter about once every 4 seconds.then let it idle,adjust the low speen till it runs smooth then make it 1/8 turn richer. Many of the new carbs require special tools to adjust, not brain surgery, just to keep the air cleaner..

After rebuild only runs on half choke.Adjusting screw doesn't help


The rebuild you did is correct, but did you clean the small ports in the carb.? I use a Den Tek Brush (used for cleaning teeth). They work great for this job. You may also want to check the small screen in the carb. The smallest of particles can cause this problem.
