Default New Way Questions

Hi, i am starting to reasemble my 4.5hp vertical hinged crankcase new way that i got as a basket case, i have a few questions 1) how are the main bearings shimmed, i presume to just use thick gasket paper between crankcase halves? 2) are the main bearings just lubed from oil in crankcase under crankcase pressure? 3) has anyone ever made a mixer for one of these, i am thinking of using water pipe fittings. i will have more later on,
thanks for any replies in advance,
cheers Chester from West Aussie.

The mains are just gasket material. You might have to try a few different ones to get the thickness right. They are oiled from inside by splash lub. Don't put the piston into the cyl until the hinge bolt is in place, then have someone hold the cyl while you insert the piston. Only push it up a short ways until you can get it bolted to the crank. If you shove it up to far, the top ring will snap out in a hollow space above the bore (combustion chamber) and you will play hell in getting it back out again. Only a few times have I heard of someone getting one back out whole, most of the time they have to break the piston up beyond repair. The mixer is only a jet hole in a peice of pipe that goes through the mixer )no needle valve) and the only control is the choke plate so I can see where pipe fittings would work for the mixer. The intake pipe is made from pipe.

One way to play it safe on the problem of the piston going up in the bore too far is to take an old spark plug and weld a piece of rod on it long enough to prevent the piston from going too far. Just be sure it reaches down past the hollow portion of the top of the cylinder bore. I hope this will help a little, good kuck in a god hobby. Joe Morris
