i typically do a minimum of 5, and generally will let them run till it stops climbing, paying attention to the first stroke.
IE.. see what first stroke does.. then see what it does past that.
I've found that 5 strokes usually yeilds max that it will make... while 1st stroke makes the most difference, IMHO, on how they start.
the gasket is either holding or it ain't. if it's such a slow leak that it's still building 100+ psi on 1 puff. i can't see it being an issue.. so I guess that begs to ask what the OP saw onthe first stroke?
I have seen some that have worn comp rings but non existant oil rings that will 'pump up' to a good #.. but be lowsy starters till oil startsgetting thrown sealing the rings.. i have an 850 project tractor that takes about 20 revs before it will start.. and it's a worn ring issue for sure.
