Hello OldMiniBikes members!
I need some help. I just bought a very clean Briggs 5HP I/C engine off eBay. It is very clean bushing block with large roller bearing side cover. It is nearly complete, but I will need the tins and valvetrain. I will be building this with the billet parts, flywheel and rod, 'cause we need no stinkin' governors! I have built a few car engines, so I know the basics and have the right tools. This will just be for chasing the cats in the neighborhood (j/k) so I am not going racing or anything like that. Here is my long list of questions.
1) How exactly do I know what parts to buy? This engine is not coming with the recoil cover...is there part numbers on the block?
2) How are the valves adjusted? If they are too loose, do I buy different valves, or lifters? If they are too tight, do I grind the valve, or the lifter?
3) Do Raptor parts interchange?
4) I am planning on shaving my eyebrows, and the eyebrows in the block. Stock compression for Raptor was listed at 6.5:1...is that enough? By automotive standards that is incredibly low. Should I look for a thinner head gasket?
5) I am getting a more aggressive camshaft. Is it necessary to weld the lifter housing if I am not racing?
6) I am planning on using a motorcycle style carb...probably one off an "Animal"...is there another option I should look at?
Sorry for the long post...I just want to make sure I spend my money on the right parts at OldMiniBikes! Hent don't want no stinkin' returns!
Thanks in advance
Eric
