The "Mongrel" lives again

After a couple years of piecemeal assembly my "Mongrel" R100S sidehack tug is in action...the first maiden voyage ended in a swallowed valve and internal "owies". We ran a 700 mile run last weekend through Montanas' Glacier Park which is just north of our currant digs. I posted a short, although poor quality, video. Still have some additions to make...alloy wheels, larger oil p[an...the list will never end...it's only money....
