Exactly when I first saw this in the parts bin I said "What engine is this thing supposed to be?". I was so confused but after doing some research I found out it's a sohc. HOW, WHAT?
Quick tip.
I don't know if you guys know this but if you put super glue In an area (liquid stuff not the jell) then put baking soda on it then it dries instantly. You can use it as a filler or to just glue stuff together. Mind you it's extremely strong so your not getting it off.
Speaking of Des Moines I think I saw some in the iowa city hobby store hobby corner if that's not to far away for you. I was looking on their online store to double check.
