Wet
clutch or fluid clutch refers to the clutch plates that transfer
power from the from the input shaft to the transmission gears. Think of it as an automatic transmission in a car with one
gear fwd and one reverse. A dry clutch would be like a standard transmission with a manuel clutch. I very much doubt if the transmission oil ( or for that matter engine oil) is supposed to be in with the flywheel and starter. The starter has no oil
seals to prevent the oil from getting inside the starter and shorting it out. Any oil would very likely become contaminated with small metal fileings from the wear between the flywheel and the starter. Would suggest removing any drain
plug on the bottom of the bellhousing (capturing the oil of course) and running it with the
plug out. This will prevent you from messing up your starter and you can
monitor how much oil you are really leaking. You may be pleasently supprised at how little oil it actually is and just continue to run it as is.
