With a lot of cussing and swearing. You have to disassemble almost half the unit. I did one last summer for a customer who did not what to take it to the Honda shop. After I got a service manual from a buddy, I told the guy it would be minimum 2 hours labor maybe more, he says I don’t care do it charge me what you have to. Took 3.5 hours, charged him three and when he picked it up says he had another one at home and it will come in this summer. Told him I’d rather not do, but he wants it done. I wouldn’t touch it, but he spends about 3K every year on equipment and repairs, plus we always see something good to drink at the holidays.
