It runs so it is done. May polish it : http://s1080.photobucket.com/albums...y Oscilator/?action=view¤t=10psirun.mp4 Brock
Hi Shedboy I agree - if it runs it done... I think however you have been doing a lot of work with the engine base (milling work) and the cylinder also, so it is a pitty not to finish up the engine with some grinding/polishing.
