    Hello everyone,
    New to this forum. I have been working on my dads Homelite UT33600A that wouldn’t star. After replacing some of the parts discuss in this forum, I was able to start the trimmer but it dyes 10 sec of releasing the accel trigger. This model has 2 positions A and B. Sometimes I have trouble starting the trimmer on A w/o some starting fluid.

    I replace the following items only:
    1. Carburator assembly
    2. Main fuel live (after inspecting the return line did not see reason to replace it)
    3. Fuel filter

    All these items were purchase at Amazon.
    I also want to add that I had to make a costume intake gasket with cereal box cardboard as the carb assembly did not come with one. This is the gasket that goes between the plastic little intake neck and the engine.
    Any help will be appreciated.

    Does that carb have any adjustments on it? If it does, try fine tuning it.

    Hello and thanks for your reply. I don’t think these carbs can be adjusted. Please see images.

    Well, ya shoulda tossed it. Ain't much of a unit to start with, right?
    But I digress...
    Did ya punch the pulse hole in the " gasket" in the right spot ?
    I hope ya used a Cap'n Crunch favorite !!!!
    The carb can indeed be adjusted, just need the trick tool, avail online.
    Cut a screwdriver slot in the needles with a dremel tool or sumpin.
    May also find a ink pen barrel that you can kinda press and turn, or the insulator part of a crimp on terminal.
    I use the tool.
    LS is near the motor, HS is near the choke. Open up the LS a tad, should keep it going.

    Thanks BigFish,
    I order the tool and that did the trick. When I bought the carb they told me no adjustment needed, so much for that. Still can’t complain, the carb wasn’t that expensive to begin with. Thank you all
