My X425 starts and runs for about 5 seconds, then will not start. Reading through posts here, seems like the fuel solenoid has failed. What super trick wrench is needed to fit between the float bowl and solenoid body to loosen it? My skinny 1/2" inch is too long and my short 1/2" is too wide. I rather not grind down a wrench. A 60* or a 90* mighh do the trick. Thoughts?
