One Cylinder vertical with Overhead Cam,  1.0 bore X 1.0 stroke  6/27/2004

I am now working on a "new" engine,  a scratch design single vertical.....The engine  is an aluminum , 1" X 1"  bore and stroke and  that it is going to be a timing belt driven over head camshaft, with cooling fan, and adjustable compression ratio ( after the engine is built)...
I  have a few things to finish working out , still things are going well at this time.......The engine should be simple to build, and is sized to be a working engine if you want it to be......It is a size #8 engine for the people with size #10 fingers.........

The engine is a 1.000" bore X 1.000 " stroke , with a .375 "shaft, block OD is 3.000", Block length is 3.000" ,cooling fins  OD is 2.750", and height to the top of the biggest pulley is 8.750".....Flywheel OD is 3.000 X 1.500 long, which includes the starting rope pulley.....I have one picture with a 6" scale along the side of the engine and I will send it to you in a following email.........The squish area of the engine can be adjusted from .437" down to about .045", after the engine is finished.

4/14/2005  I started up the single about three day ago......Had a excellent start up, only needed to set the carb and adjust timing....Had a few oil leaks, which are now cleaned up.....The engine runs from a nice idle up to a good high speed....It is fast to take the throttle........I will send a few final pictures later.......
