Just found a 1969 Honda CB-100 motorcycle. I need

Congratulations on owning a fine classic motorcycle. Best to start about 1 1/2 turns out. Maybe you can get some better advice from the guy or gal at the parts counter at your Honda Shop.

It is possible for cells to go bad in a battery. Anything that remotely resembles mold in a motorcycle battery is not mold, but it is bad news.

It should be a 12 volt system.- 6 fill caps on conventional batteries.

The hose on the bottom of the carb is just a drain hose. It connects to the bottom of the carb and nowhere else.

You don't have to split the case to replace kick starter shaft,and you don't have to remove motor,drain oil,remove kicker,then side cover.really not that hard,go for it,you will learn alot.

Mating surface at the bottom of the carb to the bottom of the float.

JP Cycles, but not sure of the size of Carb. but they will know.

make sure kill switch is not killing spark even in the run position. Chech all fuses (test them) make sure power to and from coil is there. the CDI is not repairable but could need replacing.(not sure if the cb 100 has this with points) is the condenser good? if it is it can be charged and discharged with a mulitmeter.(use ohms resistance to charge it and volts dc to read as it discharges CAREFUL it can BITE)

Hi and welcome to FixYa,

Good luck and thank you for asking FixYa.

it should be on the head tube on the right hand side, you may need to clean it up with a steel brush
