Hello, I have, among my fleet of antiques, a Eclipse Rollaway. It has a 3.5 (I believe) hp Briggs and Stratton. It has been sitting around and I wanted to get it going. I cleaned out the gas tank, rebuilt the carburator with a rebuild kit, replaced the gaskets, replaced the armature and points etc... It runs fine when sitting on the driveway facing one direction, turn it around and it dies. Strange. I have tried adjusting the needle valves but can't seem to get the issue to stop. Any suggestions?
