3 point on what? 8N, 9N, NAA....there are differences. But, as a rule of thumb for an 8N, it's probably a sticky exhaust valve. Remove the inspection plate w/ the dipstick, reach in & push the control rod to the rear. If the lift drops, you found the problem.

This is a classic symptom of a dirty pump.

Have you ever cleaned out the pump sump & changed the fluid? Check out tips 3 & 4 below.

After you get the old fluid drained out (overnight is best) remove both inspection plates & start pulling the sludge in the pump base out by hand. Then, get a couple of gallons of kerosene or diesel fuel & pour it into the pump base. Catch it in a bucket & reuse it. (Some folks use a hand garden sprayer.) Flush the pump base out 5 or 6 times. Do not start the engine to run the kerosene through the pump; kerosene and diesel fuel do not have any lubrication properties & you will damage your pump.

Some folks will tell you that this 'quick-clean' is not as effective as dropping the pump & doing a full job. I do not dispute that, but it worked for me (so far) for the past 3 years on my 1951 N. If you have the time, drop the pump; if not, you are at least getting some of the crud out of it.
