How much oil should I put in with this engine mounted with the cylinder upright? And the manual recommends 10w-30 and straight 30 for the higher temps. I'm planning to run with no shrouds, so should I change to something else or go by the manual?
Well I put 20oz 10w-30 and 1oz zinc additive for the flat tappets. My motor is angled just a tiny bit back from vertical but that might change soon. Been running it all day and it's sweet with not so much coming out as with 24.
