I did it to my husqvarna 372, i cut a grove around the flat machined surface of the cylinder so when i put sealant on it that it would have a better chance of sealing it. I used my carbide bit to do so, I will post pics in a day or so of a few other jugs im doing for local friends to show what i mean. I've heard guys on here say they've done it to, any pics and advice would be greatly appreciated!
