    I have the Husky 450 and have been using it from time to time for a couple of years.

    This week, I've run  into the starting problems you've posted above and so I began trouble shooting by making a batch of new gas mix, changing the spark plug and had no improvement. Then on an impulse, I tweaked the cylinder pressure release button UP-- not down before the yank, and the sucker started right up. Apparently that pressure release was never returning to the proper position and interfered with combustion. i hope this helps others.
