    hi guys, 1st post. i have a question. i have a mcculloch backpack blower and it will run for a little while but will not blow hard at all. i've changed the spark plug but it isn't any better. i have had the blower about 2 years and have only used it at my own home and 1 other yard. do you guys have any suggestions as to what may be wrong? or should i put it in the shop?

    Your throttle cable may be out of adjustment and not opening it up all the way.

    If you cant fix it yourself, dont take it to a repair shop. The repair is likely to cost more than what a two year old machine is worth. Put the money toward a blower that you can get some years out of like a Redmax, Shindaiwa,Echo, Stihl etc.

    Hi all, I have a smilar problem
    the McCulloch Blower Vac as the UK calls them will only run temperamentally on half choke.
    I have cleaned out the exhaust.
    What plug is it and what size spanner is needed?
    I have tried to clean the carb once. Any more ideas?

    sorry me again.
    the other question I have is that there are two pipes between the carb and the tank. When I removed the carb last time i forgot to note which way round they went. One is a larger pipe than the other. Which way round do they go?

    check the carb and air filter. Also check all of your fuel lines and fuel filter. When I started out 5 years ago I looked into the same back pack blower but when I tried it out I was not pleased. Look into a good quality commercial unit with at least a 60cc engine.
