I have a mulching mower that worked fine a month ago. Now, when I start it, it runs for 15-seconds and then quits...unless I push the rubber primer button that puts a shot of gas into the engine. Even after it warms up, it still only runs for 15-seconds, then wants to quit. I hesitate to bring it into a repair shop and pay $75 to fix a mower that's not worth that much.
A year ago, when I brought a relative's mower in that wouldn't start, they cleaned it out and said it was a victon of "old gas"...even though I typically leave gas in my mower and snowblower year round, and they always start.
Any ideas?
Thanks! Scott
