Did it run earlier this summer? Many 2 cycle motors are having difficulty with the new 10% alcohol gasoline. The vinyl tubing tends to break down and also tends to muck up with gum and goo. Does you blower have a pump bulb

Can't help if you don't describe the problem. Nobody here is a magician

I replaced the carb gaskets, fuel lines, spark plug and primer bulb. It started initially but for only 5-15 sec. I tried number of times with same result. Left it for a few hours and failed to fire at all after that. Suggestions? Thanks Mike"

No need to start a new post each time you respond, just use the ANSWER THIS QUESTION box each time. So it would not start yesterday and now you did this work, right? You did all the right things but may have skipped the actual original issue, junk in the diaphram. Did you open the gutts of the carb and clean out all residue?
