My LGT 145 with K321 is letting me down. Ran fine all last summer until near the end when it became more difficult to start. Now, it's almost impossible. Cranks and cranks and sounds like it wants to fire but doesn't, and also lots of backfiring from carburetor with filter housing off - even flames! I cleaned and reset the carb to initial settings, checked point gap which was OK, cleaned and gapped the plug, but still no go. Should I be looking at something else? Help
