Mcculloch MB3202 anti-vibration back pack leaf blower, runs better at the middle setting of the choke than it does if it's wide open the way it should be. Can't get it to blow leaves well. Owners manual lost. ANY ADVICE???????? New gas, spark plug starts on the first pull but just doesn't give out like it should.

The machine is completly flooded, remove the spark plug, switch the ignition off, crank the engine until there is no further fuel spraying from the plug hole, leave for a few hours to dry out, replace a dry plug and try again with no choke and full throttle.
If it is a 4 cycle blower, you do not mix oil with the fuel....It takes straight Gas. there is an oil cap to put engine oil in crankcase, this only usually takes 2,3,4 oz. of oil. Sounds like your Spark Plug probably fouled out from having oil mixed in your gas. I would recomend changing your Spark Plug and put some Fresh GAS only in the blower, dump the old stuff out !!! You should be on your way Blowing in No Time !
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
