Scott,
Let me say first of all I don't have any gas engines of any kind, but I do know how you feel somewhat. I have had diabetes since the 7th grade. And having been out of school for 19 years now (wow 19 years) bad blood sugars have really affected my eyes. Staying in contact with a good opthamologist is a must. Watch out for your eyes. When you lose part of your vision it never comes back. And laser surgery to keep from losing your eye sight is not the same as the corrective type. Its like getting hit in the eye with a baseball bat repeatedly by Hank Aaron.
I have also recently lost a family member (my grandmother). Not hard enough to lose your family member, but I was also in charge of funeral arrangements (not as a family member, but as a funeral director). Kinda tough keeping your family happy (everything has to be perfect).
Said all that to say please take care of your health and don't over do it at the shop ( lack of rest is almost as bad as bad blood sugars). I truely hope things will turn around for you for the rest of the year.
Do you know that I woke up early this morning and realized I fogot to send my condolences on the loss of your loved one. So I will now. I am sorry to hear about your loss.
Alan
