Personally Id leave it ....mixing aint that big a hassle . Im thinkin that getting the whole kit ....even used wont be cheap .
I figure the 50:1 mix ratio by "double it and add a zero " ( only works for litres )
10L doubled is 20 ,add a zero is 200 , use 200mls oil for 10L fuel
Oh well I'll just shut the firetruck up then .Thanks for the info, just trying to get a feel of what more experienced people think.
and hope they removed the pump parts properly.It is a cryin shame that someone with no idea what they were doing removed the oiling system. Very very reliable. Less mess. Less chance for an oil related failure.
Given the age of the motor, the availability of the needed parts, and the cost thereof if you can find them, I would leave the system as is.
