EVERYTHING IS ON HOLD AT THE MOMENT, SOMETHING UNEXPECTED HAS COME UP. CAN'T HANDLE ANY LARGE PROJECTS RIGHT NOW.
Now this is a short version mostly of lesser important matters. Anything very important or in need of more care will be covered in part 1b. If you have know how in this area, feel free to skip right to Part 2 (COMING SOON!).
So, now you are wondering, OK, great, now what about the engine.
Now, I know someone is going to tell me this, but yes, I used a very weird engine. I think it will work out great though with the specifications below:
400cc Wisconsin Engine
-Cast Iron build
-lots of torque (30 ft/lbs)
-1900rpm idle, 3700rpm max. (No load)
-the carb is made to be able to tip to extreme angles without flooding or starving
-it has an oil pump (Much better then splash lubrication)
So it has some good credentials, however, it is 60 years old, but has no wear on it which is excellent and a bit surprising even. Now, you may think, where can I pick up one of these from! Well, you can try the bargain finder in your area, and even junkyards tend to have then, and usually they only have minor problems. So there is the option of the odd engine like I used, or similar (A twin cylinder 20hp Honda, those are fairly common), or the second option.
Now the second option is opting for a standard bike engine, something that is made for a bike. These, although I can guarantee will probably be more expensive, they will require less fabrication for installment. Using a non-bike engine means it will not have the same mounting abilities of a bike engine.
So there is trade offs.
Once you have picked an engine, if its used, it is a good idea to clean it up, even if it runs. You might find you didn't get a great deal, you might find you got a great deal.
*Sorry some of the pictures are sideways, I am trying to figure out how to fix that.*
