Question about Garden

1 Answer

I have a McCullloch Garden blower powered bya McCulloch engine. the details on th Carb cover are:- N213 BVM240 99207N00116 The problem I have is that the engine will start but will only run for aprox,2 seconds and then it dies as if its running out of fuel. I have noticed that if i fill the tank, leave the filler cap offf and operate the primer I get bubbles in the tank. one of the pipes that run into the tank has a weight on it. Does that weight incorporate any kind of check valve and if so could this be the problem? Many thanks in advance. Phillip Ribton. email - ribton0@xlninternet.co.uk

The line with the weight( filter) is the main line to the carby
the carby operates by a diaphragm driven by vacuum pulses from the rotating crank and piston movement
much of your problem will be from a diaphragm that has gone hard and not sealing properly
you can either replace the carby complete ( around ($25.00 on e-bay) or go to your local mower repair shop and get a kit to replace all the rubber in the carby or have them rebuild the carby

SOURCE: Champion Vantage 35 - mower will not keep running

More than likely the jet in the carb is somewhat clogged. Did this just happen after sitting for the winter? If so, start the mower and when it starts to die pump the primer to keep it running. Sometimes it will clean itself in a few minutes. If not, carb cleaner or take the carb bowl off and clean the jet.
Hope this helps

SOURCE: kohler motor starts then carb loads up with gas

If the engine is running rough then this could mean that you have weak spark or valve adjustment. When an engine runs rough it will not burn all the fuel, which will create excess fuel in the air cleaner housing. Also, make sure the the float is closing in the carberator.

Try removing fuel bowl under carb and cleaning it. Junk and condensation can collect there. I had same problem. Did that and problem fixed.

SOURCE: I have gas going into my oil. 17.5 Briggs solenoid on carb bowl

The problem is the float needle and seat are leaking. It is not shutting off the gas when the bowl is full. The bowl fills up, then runs down the intake through the intake valve into cylinder, past the rings into the crankcase. Fairly common problem. Just replacing the rubber tipped needle probably will not stop the leak. The pressed-in brass seat needs to be pulled out and a new one pressed in also. Possibly there is some trash or rust in the carb that has gotten between the needle and seat, but in my experience, it usually takes replacing both to fix.

I either need a rebuild kit or new carb for a 40005102 McCulloch blower. Where can I find a part number for both? Mike


hey MIke,
in my experience, 99% of the time, a professional cleaning and setting will fix your carb issues...take it tot he local McCulloch dealer.. or professional small engine guy.. he SHOULD know how to fix it... the only need to ever replace parts is they are broke or worn out... ASK for ALL your old parts if they replace ANY!!!!

Ryobi 9600 backpack blower. Starts great. Set to run, continues running. Upon attempt to use throttle, engine dies. Acts like choking out but removed carb cover an choke is no closing.


this sounds strangely like the high speed jet/pathway in the carb is clogged up with something ,

the best way to fix it is dissasmbly and cleaning of carb in solvent , but ive also had some limited sucess in past of using car fuel cleaner (says on bottle "cleans as you drive") too

Mcculloch leaf blower does not blow hard enough


Hi David,
First I think I would check your exhaust screen in muffler to see if it is plugged, this would cause the engine not to rev max rpms which would in turn not blow full capicity out the tube, If this is o.k. then I would try running the choke partialy on and see if it improves the sitiuation, if so then replace your fuel filter and clean your carb out (take apart and check for gum,varnish,dirt .If you are careful you can clean this and put back together, but sometimes there is no choice but to put carb kit in...remember to clean fuel inlet screen and change needle valve,cause it has a neopreme tip snd this gets soft and gooey from ethanal in the gas now days.. you'll have it going in no time !

Where does the second gas line connect to on a mcculloch m32em leaf blower?


The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.

The engine revs high then low.


There is a way to remove fuel filter although I don't know if you can clean you might have to replace it. Other reasons for high and low revving could be that the carb might be adjusted correctly.
