We visited my FIL again tonight but hubby did not able to do the things that Dad needs help with. I think he will do it tomorrow. He has to fix something from the gutter of the house. I don't think he would need a timing pulley but Dad said that he put the things that he needs in the garage. My FIL has been cleaning his house lately. He is trying to get rid of stuff that he doesn't need anymore. I hope that Dad will live a lot longer so the kids can still enjoy his company. He is turning 90 this year.
