Toro Super Recycler with Toro 159cc
This is my fourth season with this mower without any problems. Three weeks ago I was just about done mowing when I smelled gas. I looked down and gas is dripping out the cap, appears to be coming from in between the cap and spout. Dealer gave me new cap saying (with out looking at it) it must be the seal. Put new cap on and that seemed to fix the issue. Fast forward a few tanks of gas and same thing, just about done mowing when I smelled gas. You guessed it, cap is leaking. I decided to wait until I mowed again to see what happens so I mowed enough times to go thru the rest of that tank plus a full tank. It does leak less as the tank gets empty but still leaks. This is the weird part, it never starts leaking no matter how much gas is in the tank until I'm almost done mowing, about 20 minutes or so into mowing. I can about say, ok when I get here it's going to start leaking and sure enough it does.
If there was a crack in the spout wouldn't it leak all the time or at least any time gas splashed up that high? Or is it building up pressure from the cap not letting in air and finally gets to the point it pushes it out thru the cap? How about a heat issue since it only happens after it's been running for a while, is the tank getting hot and possibly opening up the crack?
Any thoughts?
