RE: Let's try again DL-50

Hi Chad,

The Bling weighs 15lbs 2oz with a full tank of gas. It was a bit lighter before all the repairs. Also, I have nothing new to report on the future products.

RE: Let's try again DL-50

Home Depot sells 8oz cans of Lawnboy Ashless which is what we use for break in. Use it to mix with 2 gallons of gas and you have your break in fuel taken care of.
