To the gentleman who wanted to know which bar to use on the Mac 250. I use a large mount 009 Husky bar in 3/8 .63 you’ll have to open up the slot width about .010 with a dermal or file and I use an 1/8” bit and drill straight down to the oil hole which will let it oil with the stock bar guardsI signed up over there. I didn't figure out how to search out members , Maybe tomorrow.
About the saw I'm sure I will be asking you guys questions about it's faults and ways to fix it. Thanks ,
