I am so aggravated! Got new fuel lines, primer bulb & filter for this trimmer & still wouldn't start. Took carb apart & check valve flaps were stuck tight. Got them unstuck, but they are pretty stiff. I do have her running, but has to have choke 1/2 closed. Runs with plenty of power when I get the choke set right. Here comes the really aggravating part......I cannot find a carb kit for this carb. ALL that I can find is a brand new complete carb at over $40, part #753-1225. Heck, this will be almost 1/3 the price of a brand new trimmer! If anyone knows where I might land a kit, please let me know.
For now I'll just run it with the choke.
