208 cc lct gas cap venting issues

my lct powered snotek has developed a gas cap vent issue. i did overthink it before tonight. was planning on pulling the carb tomorrow for a cleaning.
symptoms....would run perfectly for ten minutes, then start hunting, then stall. it would start back up easily, run for less time and hunt/stall. tonight i had to use it again, and it was worse....20 ft, stalled, 10 ft stalled. was getting ready to wake up orange crush but thought id try a hail mary and loosen the cap.....machine worked perfectly.
short of a new cap or drilling and plumbing a vent, is there any known fix ?

Try loosening the cap and see if it will run ok for an extended time period. If it does, then it's not venting. The solution is a new cap or take a sewing needle and grasp it with locking pliers. Heat the needle with a propane torch until it glows then pierce (melt) a tiny hole in the center of the cap. I had that problem and making the hole solved the problem. Make sure the cap is thoroughly dried and aired out first so no fire issues Never had any probs with water in fuel because it was such a tiny hole. Much cheaper fix than a new cap. If you can pierce with needle going from inside cap surface to outside surface, you will probably have the smallest hole (doubt that it makes a big difference).
