1988 Johnson 225 VRO acts up at start up

[tgleeson]

Engine acts up at start up. Smokes and seems to miss fire. After 3-5 min it seems to run ok. The rest of the day it runs like a new engine.<br /><br />Can anyone tell me how the choke system works?<br />Maybe somthing is sticking or needs to be cleaned? <br /><br />Thanks<br /><br />T J Gleeson

TGleeson.... By any chance are you pumping that oil primer bulb before starting the engine? If so, don't do that as it temporarily creates a higher percentage of oil in the mixture.<br /><br />Or.... are you neglecting to pump and prime the fuel primer bulb on that initial start procedure? This creates the same problem as above.

I do not pump the oil bulb and I do pump the fuel bulb. The engine starts right up but smokes and runs rough for 3-5 min. <br /><br />What is the best RPM for warm up of engine?
