i watched this before i joined and laughed at it . it is very possible to take a bottom drive and turn it in to a side drive but, BUT the way this guy went about doing it,stupid realy stupid . the case would not handle it . now if you built a mounting plate that bolts to the original mount and turns it 90 much better . the oil problem is not all that big you take and set it up same as a side drive with a dipper . simple bolt on part , the next problem to solve would be how are you going to fill the oil the fill is now the drain plug .you would need to make some kind of oil fill set up .with pipe fittings you could bring the oil drain up to a level with the full line .
the carb you make a intake how many here have done that ??????? not so hard if every one here has done it . if you take a side and bottom drive motor apart and look part for part you will see that there is no real difference in the parts . some things are different yes but nothing that you couldn't work around .i had thought this out when i was a kid , and figured out how to get around the problems . i should build one like this just for the fun of it , maybe this summer ill get to it .and then we would have proof if it works or not.
minidragbike im going to call bull on the vertical flywheels are not balanced . if they weren't balanced then there would be some massive shake in the motor . and i know that the cranks and flywheels are in briggs motors are the same in alot of the motors . i seen some of the older cross reference lists and all the same 1 part with 50 numbers . and i know for a fact that the smaller flywheels will fit i have many times used a heavy flywheel off a push mower from the 70s on a side drive and it was the same part , same with the cranks .
