5HP Budget Build Up

[solomon]

Hey guys, I have been bored for sometime so I figured I will do a 5HP Briggs Budget Build. I have a Standard Bushing Block that has some intake porting and soon exhaust porting. I plan on boring over .020 (I know a guy). I'm going to shave the eyebrows and mill a head for it. I need a head so if you have one let me know. I think I will Get some extended lifters and grind the lobes on the cam a little for them to fit correctly. I figure Im going to use a 10HP Tecumseh Carburetor so an intake will need to be fabricated. I also need a starter cup and pull starter assembly. The Governor Has already been removed. Im looking for a bearing so I can use my bearing side cover. Anything else I should do? Maybe advance the timing via the flywheel key? I'm on a budget already and a new Piston and Rings is in order along with gaskets and seals. A bearing, connecting rod,flywheel key, and any other missing pieces. So my budget it getting much smaller =P. Any advise or oppinions would be great! Thanks

straight pipe, gain about .7 horsepower from stock just from this

Most Likely me with a bench grinder, just to make the lifters close all the way when they should, so the lower part of the lobe. Shouldn't need anything precise, but i know it should be smooth.

Holy thats some backyard mechanic work! You milling the head with a wood rasp too? Also dont forget the end of the lifters must be ground with high precision and must be square as well.

i perfer to use a hack saw

haha defiantly back yard mechanic. How could I do it at a machine shop. I would be usinga manual mill to do the head.
