I have so many questions regarding building up a Briggs flatty that im not sure where to start. I would love to get someone on the phone.....or even better is there anyone in CT that can teach me a thing or two about a rebuild?
here is my dilema.........the machine originally had a early 60's Tech H60 in it. The engine was rough and i did "restore" it. well i also have this Briggs flatty sitting on the shelf and i started to think.....what if i build this baby up a bit and swap it out for the tecumseh. i prefer the briggs over the techy anyway and aftermarket hop up parts seem to be more available for the briggs. im thinking with a rebuild and some add ons i can probably get more HP out of the briggs then the H60 anyways. so without further ado here are some of the many questions i have about building up this briggs abit.
1.exhaust..........my issue is that this is not a mini bike so im not sitting on top of the motor. In fact the motor is in front of me with the exhaust blowing at you. Does anyone know of a aftermarket header that kicks out to the side or front of the motor or maybe even straight up like a tractor exhaust?
2. If i decide to do a rebuild and get the cylinder bored out to 1 over stock and use a 1 over stock briggs piston and rings am i still ok to use the 3.875" ARC billet rod?
3. Im doing the rod so i can ditch the governor obviously for higher RPM's.
I do not intend to "race" this motor in fact its going in a vintage snowmachine. It will mostly be used for ice fishing and putting around the farm. That being said is there a way to build more lower end tourque or will that increase with HP increase? im still trying to learn all this.
4. "porting".............i took my exhaust off. It was bolted on. inside the port there are ridges or what i believe may be threads. is this what im trying to smooth out? the intake side seems pretty smooth but i do fell this rather large bump in the upper right side of the port. is this normal or does this get removed also?
5. i think im going to use a tilly H60 carb for starters. Does this carb need to be modified in anyway to work with a built up briggs? anything need to be drilled out to feed it more gas or can that be taken care of by simple adjustmants of the screws?
i have so many more questions but i will start with these. I read the sticky about mods and it makes sense but i just need some more clarification. never attempted to hop up a small engine before. I can fix them all day long but never got into performance mods. Anyone willing to let me bend there ear for a few minutes on the phone sometime soon? anyone know a good builder in CT? I prefer to try and do this work myself.
