Carb adjustment on McCulloch 32cc?

I have a McCulloch leaf blower that only runs with the choke partially closed. It is a 32cc and I believe the model number is MB3202. There appears to be two adjustments on the carb. If these are adjustments, can anyone tell me what they are. If they are idle and run mixture adjustments, which one is idle and run? (The fuel is clean and lines clear).

    Thanks stihlpower! The adjustments are not labeled, in fact they are not your normal screw. They are flat plastic-like adjustments inside a case with a **** for a screwdriver. They are right next to each other. I have experience with engines and I have disassembled the carb, soaked it and cleaned. I did not find a screen or filter of any type in iy but I will look again. I did make sure the fuel line was free and open. I'll open it up again and see if I missed something. Thanks again!!!!

The l is for idle and the h is for top end but thats not ur problem it sounds like ur carb is clogged there is a screen inside of the carb the fuel gets crystalized and blocks off some and sometimes all of the fuel ill bet thats the problembut u can try the adjustments first give the unit full throttle and turn the h adjustment screw in and or out till it sounds great and at full power if that dont work then do the screen in the carb

How do I unclog the carb on my push mower


Haha, nice one, but I am smarter than the average bear.

A PUSH mower does not have an engine, so therefore it does not have a carburetor.

I have a Ariens snowblower deluxe 30 which is a year old. Starts fine and will run. Unfortunatley it is running way to low. I have replace the gas with fresh gas ran it through completely


It is very possible the carbureator needs a cleaning. Moisture can corrode the inner parts of them if left all summer. I find that the fuel usually does not go bad over the summer. I always start my snowblower once a month over the summer and then have no problems when the snow flies again. There was a time when mine was losing power and quitting also. There is a screw on the bottom of my carbureator that needed adjusting. If you are lucky that may be all you need. By turning mine in and out a bit I found the spot where the gas was correct and it worked fine again.

check the blower motor itself and the plug. some makers still hide spares or mains in the actuall plug. if you've still got the box, it may have been in there.

My weed eater will not run with the choke setting wide open.


You may have a pinhole or crack in the small hose that runs from the fuel tank to the carburetor. If equipped with a primer it may also have a small crack or pinhole. Either case may cause the carb to suck air instead of gasoline. Other possible reasons are a plugged muffler causing too much back pressure or a partially clogged fuel filter. (The fuel filter on many weed whackers are located inside the fuel tank at the end of the fuel line.)
