    Greetings,

    I have a question. Does anyone knows the procedure to find the piston TDC (not timing chain) for Husqvarna TE-250 2004?

    I search over Internet and found that there is no piston mark on flywheel for this model, and found various posts that they were using a straw in the spark plug to find out the TDC.

    Thank you in advance,
    Cristian

    You can find TDC on just about any engine by inserting something in through the spark plug hole, say a small screw driver inserted up to its handle, you want it to protrude far enough in to contact the piston somewhere just before TDC. Rotate the engine until the piston just contacts the end of the screw driver, mark that position on the flywheel. Rotate the engine the other way and mark the flywheel again when the piston hits the screw driver. Halfway between those marks is TDC.

    This explanation started OK but ended on a very confusing note.

    Here is a shop manual for a 2007 TE250, have look thru this.

    Makes sense to me, mark the point at which the piston engages the screwdriver say on the compression stroke, then as you cycle to piston through the power stroke you mark when the screw driver disengages the piston. So you now know that exactly half way between the two,points will be the top of the piston's stroke. Actually pretty good idea!
