Hello,Stew.
I simply overlooked the two exhaust holes.
Actually I'm not very good in reading drawings.
Let me say thank you for sharing the plans.
I really like your kind of building reports as well.
Very informative and a pleasure to read.
I've learned and still learn much from you.
Being an autodidact in modell engineering
without people like you,I wouldn't be able to build any engine at all.
