I also have a Huskvarna rider, mine would run for maybe 15 minutes then quit, let it set for awhile and it would start again, I replaced my plug, coil and stator to no avail, it was the fuel bowl that was dirty I took it off cleaned out the (Too much to believe junk) bowl and around the float. No problems since. Good luck!

Good job mac.

The bowl might not have been put back in correctly so when the gas enters the all it will do is leak out.
