    The choke switch keeps popping out of the bracket when I turn off. This saw will not shut off There is a spring loaded piece of metal below it keeps popping out of place

    170.

    Any ideas

    If the switch shaft is not brokeen the contact spring should ride on top of the detent in the end of the switch shaft, that will hold the shaft down in place.

    I have an 034 with this type of problem and I have not been able to use it for 10 years .When you put the choke on and hold throttle wide open the choke pops off!:angry2::angry2::angry2:

    Common problem. They would replace it under warranty if it started soon enough.

    If not, you need to remove the switch lever and lightly heat the holding bracket and slightly bend it tighter, which is hard to do correctly...

    Otherwise, you need to buy a new crankcase, which is easy enough to find....

    So does the hook on the left side just bend down and away from the crankcase allowing the shaft too much wiggle room and it drops out?

    Spring seems to set correctly and I can choke and start but when I try to shut off it pops up behind the switch and pushes the whole switch out of the seating bracket

    That seating bracket is supposed to be shaped more like a hook so that the control switch sort of snaps into place on the left side.

    Make a tiny hold down bracket to brace it out of like a carb plate or something then use two self tapping screws and jb weld it.
    You are talking about the metal shaft that clips in on both sides right?

    Well then, I won't bother.......

    If it pops out of the "hook" too easy!!! Well????..........

    The other guys are not visualizing what you are talking about.

    Either the shaft is worn, or the "hook" is weak/loose........

    Or your thumb has been up to the "Devil's Business"..........

    By gawd, has anyone here worked on these turds?

    Sorry, I apologize in advance.................

    The rod is soft too!!!!!
