Should replace
O-rings
Avoid fuel leakage:
- Carb "Tee" x2
- Carb bowl x4
- Carb flow tubes & vent "Tees" x8(x4+x4)
Avoid Air leakage(leads to lean):

- Valve-train oil pipe x10(x2+x8)
Avoid low oil pressure/dirty oil contamination?:
- Oil filter tube x3?

Must clean/rebuild
Carburetors
- Check and replace with same jets & emulsion tube or reuse (order individually by size, no kits)
- Reuse needle (do not trust "kits")
Hydraulic Tappets
- Follow manual for removal
- Use allen key (my recommendation), smooth bore side of 1/16 drill bit (Clymer manual), or special tool Honda 07973-ME9-0000 to bleed out oil
- again bleed upright under kerosene (mineral spirits or maybe even diesel fuel in a pinch?) to clean
- bleed out the solvent from the last step
- bleed under engine oil until primed (pushing on the taper without the "bleeder pin" should feel like it is basically completely solid
- keep upright and install with the tappet lower hole toward the (toward spark-plugs) squirter?
