Hi, this is Jim Snow. I have some experience with people telling me it's impossible to remove this big from the cylinder. Early models you could easily put a wrench on it, but on later models it was so tight there that you couldn't put a socket or a box end or anything. When you try to open it it just rounds off the flats. Later they changed it to a spigot that uses an Allen on the interior. I'm going to show you here that if you do mess up these threads they are the standard spark plug threads. 14mm 1.25mm. So a spark plug tap will clean those up. If you cannot get the spigot off the cylinder sometimes they are seized and you're having no luck with the socket or an open end wrench what I do is I take a vice grips a really good pair, very sharp and just clamp it like I show here. Clamped in a vice with soft jaws and then I use a large adjustable wrench to get on the vice grips and then I can very easily rotate brake loose this spigot and get it started and get it out of there as you can see here. And I make this video only because if you don't figure out this little trick it can be very frustrating trying to remove and replace that and I recommend that if you replace it you use the one that has an Allen in the center as I show here. There are some variations in diameter but not much mostly they're all the same through the years. Here you can clearly see I'm showing the two of them the variations I'm showing here the one on the right is the one that uses an Allen and I pointed out there this way you're never struggling again with a wrench or a socket you just put the Allen wrench in the center of it near the fiber washer and then it screws right on there. They should have been like that all along so that's what it looks like with the new style installed. Thank you for watching my video.
