well here is my finished popcorn engine build from plans by stew hart, thanks stew for the plans were real good and a fun build.it runs good off my airbrush compressor but it still needs a little more run in,then a paint job.do not know how to do a video but when i do i will post one,never down loaded a video to computer so not sure what the process is.stew thanks for the excellent plans now working on the simpson and shipson and is coming along good,just ordered the flywheel.
