Question type: Maintenance & Repair

some times it will not start when this happens I do not know why the oil is
getting there I can eventually get it started by cranking for a long time I guess
I am burning the oil out could it be a faulty valve seal it does not do this every
time I stop it some times I can start it for a week with no problem

It could be a leaky valve seal or bad oil control rings. If you install a plug with a hotter heat range it can burn the oil off.
