ariens wont start!
I have an ariens with a 3.5 tecumseh on it, it's a tempramental old thing, I cleaned the carb and got it running pretty well by adjusting the carb. as i was cleaning up afterward i discovered the bracket that goes between the carb and block laying on the floor, the next night i took it apart and put the bracket on and as i was trying to start it it was backfiring and wouldn't run. I have no clue from here, any help would be appreciated. thanks.
My guess is you just have to readjust the carb. I think that spacer affects the fuel/air mixture. Start and 1.5 turns out for the bottom screw and 1 turn out for the side screw. Were the gaskets still good and did you have a gasket on each side of the spacer? I have heard bad gaskets causing air leaks can cause poor/lean running.
