Hi Tyler, I'm fairly convinced the problem is in the seat more than the needle. I now have 5 needles sitting there and holding fuel with the tap left turned on for 24 hours. I have polished up all the seats with Autosol on the cotton bud and I'm now fairly comfortable I could fit these to any mower and not have problems and even comfortable that if the fuel is left turned on it won't cause issues. You can only tell people so many times to make sure the fuel is turned off. Now my next test will be on all the needles I have in the reject container to see if I can get them to hold fuel as well. That will be interesting and hopefully polishing the seats in the caps will fix it.Another thing I have noticed with polishing the seat is that every needle moves up and down without sticking in the seat. It was always 50/50 before. Stay tuned I think I have solved it.
