Symptoms:
1. Increasing oil consumption
2. Smoking at start-up
3. Heavy smoke at idle after last outing
Checked:
1. Main tank vent line to airbox. No oil in line, airbox dry. Main
tank stops filling at top line.
2. Pump discharge amounts within specs at ea. line. Checked at
carburetor.
3. Found oil behind pump and in mounting recess in block. Seal
wet but doesn't appear to be torn.
Oil pump is original not updated model
Questions:
1. Does oil leaking past seal enter the cylinders? How?
2. Is the seal available or should pump be replaced?
3. Does replacement pump have everything needed to do swap?
4. Do I have to replace anything else, eg. the driven shaft from
the motor?
5. Can an amateur do this?
Many thanks, Hawk
