1237.0. "Johnson 70hp problem when warm starting" by POLAR::STEWARTN () Thu Aug 17 1995 13:55

    I have a 70hp Johnson that runs fine when warm, but if you shut off the
    engine and restart quickley (w/ choke)it coughs and hesitates. Could
    this be a choke related problem ?
    
    I am planning on re-building the carbs soon, and changing the
    floats,needle valves etc.

	Not sure I quite understand....but why are you attempting to restart the engine with the choke ON if the engine is already warm? It's not necessary to engage the choke and will, indeed make the engine cough and hesitate.

	When I re-start I have to use choke no matter if the engine is off for 1 minute or 5 minutes.
1237.3	Sounds like it needs a good tuneup...	SUBPAC::CRONIN		`Mon Aug 21 1995 09:39`	7
	RE: .2 I have a 4 yr. old 70hp Johnson. When it was new I had to fuss with it on cold starts. It's less fussy every year, easier to start when cold. Warm starts have -always- been just a touch of the key, no choke, no prime. B.C.
