Question about Leaf Blowers

Poulan pro bvm200 leaf blower/vac won't run on high

Won't run at high speed.  gas and oil mixture is ok, spark plug ok, the carb adjustment screw will not adjust to where the blower will run at high speed.  It surges like it cannot catch from low to high speed.  compression is 60 at cold.

Howdy I'm unable to keep my Poulan Pro PBV200 leaf blower running unless I keep the choke three quarters of the way closed. Gas and oil mix is new and changed spark plug. Could the exhaust be blocke


Yes, There is a spark arrestor screen on muffler. It could also be a carburetor that needs rebuilding or a simple fuel mixture adjustment.

Blower vac runs at high speed but wont idle


Low speed circuit on carb is blocked. You can try using fresh fuel with some high quality cleaner added and run it through and see if it clear. Otherwise it means the carb has to be removed for cleaning. Which is especially hard these days with the EPA carb plugs on the mixing needles. These plugs are to minimize tampering by owners. You need to be a licensed shop with the tools to adjust the carbs and then put new tamper plugs on nowadays..

Be safe and good luck!

I have a Poulan Pro BVM200 blower that will not run. I've cleaned the carb, changed the plug, and added new gas. It will fire up with starting fluid and die within two seconds. I tightened the head and...


turn the needles all the way down to where they just stop dont tighten to tight just when they stop then back them out 1 full turn and see it should start then adjust from there if no start or runs wildly then a carb kit is needed

Leaf blower starts and runns ok for few mins then


Target your inspection towards the 'spark arrestor screen' in the outlet of the muffler.

Overfuel or 'rich' condition
Basics to check:
1) Spark plug - brown or dark brown - OK
a) is it carbon or fuel fouled
b) is there spark

2) Muffler remove for inspection
a) exhaust screen clean or plugged
b) inspect cylinder wall/piston as the flywheel is slowly rotated
3) Check Air filter for fuel saturation
4) Allow engine to run for 5 minutes to excess fuel from muffler
5) Fuel mixture ratio: Make sure the oil mix is per your manufactures recommendations
6) If after the above the engine is still smoking and blubbering:
Adjust carb mixture screws to a 'less rich' setting
*NOTE: only move mixture screws 1/8 of a turn at a time,
and try operation before any more adjustment

My weedeater leaf blower never gets up to its' old speed. Runs about 1/2 the power. Tried a new spark plug and air filter. New gas didn't help.


Basics to check:
1) Spark plug - brown or dark brown - OK
- aluminum or silver - piston/cylinder scored
a) is it carbon or fuel fouled
b) is there spark

2) Compression - 125 to 150 psi

3) Muffler remove for inspection
a) exhaust screen clean or plugged
b) inspect cylinder wall/piston as the flywheel is slowly rotated

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
5) replace gaskets/diaphragms
b) use a spray carb cleaner to clean jets, holes, and body of carb

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
