Hi. I'm new to this site. It seems to have the most DB activity compared to other forums.
I received a David Bradley 917.5751 recently. It was built in the late forties and has the old-style T hitch coupler beneath the frame.
I spent a couple hours yesterday to get it running (no luck). It has a Briggs & Stratton model N engine and 6.00-16 Agricultural bar tread tires. One of the tire's tread casing has ruptured and the inner tube is bulging through. As an interim measure, I deflated it and sandwiched a few pieces of leather beneath the tread to protect the inner tube for the time being.
The engine has no ignition spark. I'll have to remove the blower shroud, flywheel and take a look at the points and condenser. The Flo-Jet carb probably needs an overhaul too.
PS Thanks to Dan O'Connor (DanO) for posting a lot of helpful DB technical info at Youtube.
