I have a few xl-2's and super 2's with the red gas caps. They all have cork seals and they all leak when upside down. There is no hole or vent on the caps. How does it vent, why does it leak, and how do I fix it?

Most likely, they're leaking at the duckbill valve. This valve is what vents air into the tank as fuel is pumped out. Remove the starter cover and look at the fuel tank near the top and to the back side. You may see a small hole if the value is missing, or maybe melted rubber goo from where one disentegrated.

YES!! Thank you. Took off recoil cover and found hole. Coincidentally, I was emptying the tank of gas and from wherever fell out the old duckbill! Now can anyone tell me where to get them. I have six little reds with the same problem. And which way do they go into the hole? Does the rubber tip go on the inside or outside of the tank?

The valve is inserted from outside with the lips pointing in. The open hole is on the outside, so air can be sucked in, but the lips close so no fuel leaks out. There's sellers on ebay that have 'em. Best deals are on 10 packs. You can find a few for less than $15 for 10. You can google "homelite duckbill" and find other OPE sellers.

All Great. Thank you very much! Now, in the mean time, I found a couple of duckbills at my local mower shop. He wanted 6 bucks for the little tip!! NO stem and he did not have any. I was lucky enough that the stem (tube) with tip attached fell out of somewhere (prob tank) when I took off recoil and gas cap an turned upside down. So I bought one tip for 6 bucks so I could get one saw working right. Now can I also get the stems online and how much or are they included in the 10 packs?
Eager to get all my runners finished. Now have 6 little reds and two EZ's.
On a related topic. One of my EZ's, which vent from the cap, was also leaking when turned upside down. Found a NOS cap Mfg 1994 at my mower shop and it leaks! Does the cork age after 20 yrs so not tight any more? Can I put anything on it to fix? Are these also available online? Am also missing an oil cap from an EZ. Also available??
Thanks again!
Larry
