Hard starting Johnson ten horse.

[Ufatz]

The motor is a nice 1975 9.9 Johnson. Lots of new stuff on it, including new tank and hose etc. I pull choke ALL the way out and then start pulling starter rope. Tonight it took 17-arm wrecking pulls before it would start. Bulb is hard. Plugs perfect. New condensors. Fresh gas. When it starts it will run just fine and propel my tired old assets across the lake just fine. But whats with the hard start?

Have you checked if pulling the choke out is making the choke valve move?

Is it also hard to pull ? It's only a 9.9 it should not be very hard.
