200 HP Johnson 1989, I have made all what you, the experts, have told me to do , but I see in this forum and on the water that this is a common problem in all 2 strokes engines. Why?<br />Cold or warm it starts ok, revs for 30 seconds ok and puff!! stops!, four to five times starts and stops... and finally it runs perfect.<br />It is only a problem at the starting, very similar to a car that is cold and you have to choke it, but these engines do not have a choke.<br />IF it is gas or electric failure it should affect always the engines, but they run perfect after they start. <br />Thank you for your reply, this is a great forum .
