I finally got the Air-Cooled engine for Chalk Bug started up for the first time. The Bug went underwater during the Hurricane Harvey Flood in 2017.  The exhaust system was the only thing that was on the bug during the flood.  When it first starts, a lot of rust blows out.  I still need to finish tuning it then install it into the Bug.  Progress is slow but steady. I don't have a lot of time to work in the garage lately. 

This is the Break-In run for the 1776 Aircooled for Chalk Bug.  The tach on my start box is off by 500 RPM so the engine was running at 2,300 RPMs for 20 plus minutes with the occasional throttle ups.
