Hello everyone. OK, I bought an already built biplane. The seller said he had a 40 in it. Now I am stuck because the throttle pushtod is installed and it is at the top of the firewall. Now here is the problems that I am running into. What engine can you buy that when you turn it sideways, top to the left, that the throttle will hook on the left side of the engine where you typically have the highspeed adjustment? Also keep in mind the cowl is precut... to where you have to turn the engine to the left. I tried using the OS LA Blue 40 but the muffler he the side and wouldn't leave enough clearing. However, I still needed to cut a hole in the firewall and move the throttle pushrod. I am trying to get an engine so I don't have to cut the cowl on the left side and have to try and coverup the right side of the cowl. I would order a new one but have no idea who manufactured it. sighhhhhhh...If someone has an idea of who manufactured this and where I could order a cowl please let me know too. thanks for the help guys
