Hi all,
Before I go separating things more than I have to I wonder if anyone can confirm that standard valve seats in a B1 1500 motor are ok for unleaded petrol?

Any unusual things/weaknesses which should have attention while the engine is out for a freshen up. The engine has only run occasionally during the past 18yrs, but it has had a couple of oil and radiator fluid changes in that time.

Cheers
Goku
