Well that is funny that you mention flat head with a gear drive.
My mom always said I have a flat head
My dad called me a gear head
My wife says I make more noise then I"m worth
And ever since I broke the chain on my bicycle peddling up hill while standing
My friends call me a nut case
My grandpa whooped me with a fan belt for stealing his rolling papers.
Thank the lord my grandma never heard the word Camshaft when I called my sister and ***.
