A stuck float in the carb can cause this as well as old gas do to schlack build up from gas evaperating the carb should be removed and cleaned with carb cleaner and old gaskets replaced a carb kit will run about $20.00 and avail from small engine shops.
the engine number will be needed for the right kit at the bottom of the engine where it mounts there is a flat boss with a number stamped that will be needed for parts.
when the engine is stored the best thing it to run the engine and shut off the gas and run till it stops this will get ride of the gas in the carb there will still be a small amount left in it but follow recommended long term storage prep from the manufacture. hope this helps

Have a PB-250, ran great but now only runs full throttle, does not idle low.


You've been running the unit with the wrong oil to gas ratio and now the unit runs rich - there is no real way to fix it at this point - you can adjust the carb but it will not probably hold the idle you desire - but then again blowers are to be ran wide open 85% of the time so don't sweat it too much on this unit but practice better maintenance and a proper mix ratio in the future.

Generally this is a fuel / air ratio problem. Usually it can be solved by a carb adjustment. On the carb there are usually two screws, one marked low or L , the other marked high or H. Low is your adjustment for idle mixture, high is for mixture at full throttle. The saw should Always be adjusted to run well during the cut. Make adjustments a little at a time, then try The saw. Continue small adjustments untill the saw is performing well at full throttle while Cutting.

You need to inspect the throttle mechanism at the carburetor. When you pull the throttle trigger, it should move the throttle arm to it's 'full on' stop, and when it is released, the arm should come back to the idle stop screw. If the action seems to be indefinite, take the throttle trigger mechanism apart (make notes of part placement as you go), and clean it of sawdust and dirt. Don't run the engine until the throttle is working correctly. The 'stop' switch may also be full of sawdust, or the connecting wire may be damaged. Make sure the carburetor fasteners are tight as an air leak behind the carburetor can cause engine racing. Hope this helps!

40 hp mariner outboard runs good in gear ,but will shut-off in neutral ,won,t idle


You need to pull the cover and track where the trottle cable goes to on the motor. If you have someone open and close the throttle while you're watching you will find the linkage that it controls. There should be some kind of an idle ajustment screw there that you can readjust to increase your idle.

Will not hold idle, runs fine at speed


check your Idle air valve thats what keeps your car with the right air mixture or check you idle screw for proper rpms usually they are under 1000 rpm 950 around there but i suspect it might be you air valve sensor the idle screw usually dont get outof adustment because if set from factory but is something you can look at

Hello:

From your Description it Sounds like the Exhaust is Restricted or the "H" Mixture Screw Resuires Adjusting.
>>The Following is a Basic Instruction File for Doing a Diagnostic on the Engine for this Problem. Any Input is Appreciated.
>>**Remove the Muffler and Make Sure the Exhaust Port is Clear.
>>If it is, then Try to Start the engine with the Muffler Off.
>>If it Starts and Runs Properly, then Clean the Spark Arrestor Screen in the Muffler or Replace the Muffler if Required.
>>The Following is the Instruction File for Setting the Air Mixture Screws. Any Input is Appreciated. The Procedure is the Same for 1 or 2 Mixture Screws, Just Use the Instruction File and Skip Over the Section with the Missing Mixture Screw ( Usually the H Mixture Screw).
>>Now Setting the Air Mixture Screws:
>>****Turn the Idle Air (L) and Main Air (H) Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns. Set the Throttle Full Open, Start the Engine.
>>Turn the Main Air (H) Mixture Screw Clockwise Until Proper Revs are Obtained. **Carefully Use your Finger and Move the Governor Arm to Rev the Engine (on Chainsaws and Trimmers Use the Trigger to Rev the Engine) Until you Reach Max RPMs (on Chainsaws and Trimmers, the RPMs are Not Set to MAX. Set to Max and then Reverse the Setting Screw 1/4 or 1/2 Turn. If the H Mixture Screw is Set too High; the Engine will be Starved for the Oil in the Gas and Damage the Piston and Jug/Cylinder) and the Engine is Running Proper at Full Throttle Up a Grade and for Chainsaws and Trimmers they Do Not Bog DOwn Under a Load. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs.**
>>Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required.
>>Now Set the Idle Air (L) Mixture Screw so there is No Hesitation when Rapidly Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.****
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck

Blower wont run at full throttle


Start with the spark plug it is the easiest.

But sounds like the carbourator is dirty, Probably fouled with old gas varnish. When it is idling give it a little throttle, flip the choke on and then full throttle. If it goes full throttle and doesn't conk out, it is a fuel issue.

Good Luck
