    I have a redmax trimmer that has been giving me problems this year. Beginning of this season it was hard starting and a had to run a heavy choke when it would run. I have since then rebuilt the carb a replaced some gaskets on the trimmer as well. It was running great for a week than it started acting up again. It now will start up but as soon as you give it any throttle it dies. When it does run it has to run a heavy choke as well. Luckily I have a backup trimmer but would like to get this one running to have as well. Any suggestions are greatly appreciaed.
    Thank You,

    Mike Z.

    That carburetor has an inner idle needle that can be turned with a screwdriver
    to adjust the fuel/air mixture ratio, as seen by #17. There's a tamper resistant
    plug that needs to be removed in order to gain access to the needle. That black
    line in the illustration, above the needle, represents the tamper resistant plug.

    I am having issues with the same model, BCZ2601Z, this thing has never run correctly. You need to have the choke half on for it to get any power. Too much gas and it dies. Do you have these photos available? Would love to figure this thing out as it has only been used for home use and now I need it for business.

    No argument with any suggestions mentioned. Has the intank fuel filter been replaced. Have fuel lines been inspected(inside as well as outside fuel tank) for cracks or extreme softness. The most common fuel line leaks I find are at sharp fuel line bends outside and immediately inside the tank bushing inside the tank. A soft fuel line may allow adequate fuel flow at idle, but when the carb calls for fuel the vacuum can suck the line shut.

    You may want to check for air leaks in the intake area as well--bad gasket, crack in isoblock, etc.

    I used the BCZ2601Z on friday with no issues, I found the sweet spot with the choke and it ran strong all day. I feel like it needs some sort of adjustment made to it. Thanks for the feedback dutch I will check everything you mentioned.

    still having issues with this trimmer, it just dosen't want to run. The latest step I took was to replace the ignition. The thing will not stay on unless you are giving it gas.
    Step 1; replaced fuel filter, air filter, spark plug, and cleaned muffler.
    Step 2; replaced ignition on the trimmer
    Step 3; sprayed carb cleaner into it, guess I need to rebuild the carb??

    Any other advice prior to dropping off at mower store or buying new?

    Thanks guys

    I'd just buy a new carb and change it out myself. Usually 40 bucks and easier to change than all those fuel lines. No sense in paying 80 an hour for that, imho.

    That is exactly what I ended up doing. Picked up new fuel lines and a new carb for $65. Half hour later it runs great. Are these things worth rebuilding or just pitch it and pick up a new one when needed?

    thanks again.
