Hello. Newbie here. I recently purchased a used 2007 LA140 with the Briggs 23 HP engine. Overall it is in very nice shape but needed a few adjustments. It has the common problem of hard starting, which from reading other threads is valve adjustment related. I've downloaded the L100 Repair manual found here and watched some of the valve adjustment videos on Youtube and am confident that I can do this job. Just have a couple questions.
How do I verify the adjustment spec for my particular engine? I found a document that listed the adjustment spec as .004-.006" for numerous B&S V twin OHV engines but don't know if mine was on the list. I did not see the adjustment spec in my owners manual but maybe I missed it.
Should the valves be adjusted to spec. hot or cold? It seems to be more difficult to restart after it's hot so clearances probably change slightly as heat builds in the engine.
