'81 50 HP Evirude O/B won't "warm" start

[Mikki]

The engine will start and run fine cold. However, if I shut it off and try and re-start, it will turn over but won't catch. If I continue trying, I can smell gas around the engine. I have an OMC O/B throttle. Is there a manual choke that I might have set wrong?

Look on the Carb. for a Red Lever. It should be in line with the front and rear of the Carb.

I have looked and it appears that the choke is controlled by the throttle. There is an electrical piston that operates the choke. I have traced the wire to the harness leading to the throttle. The throttle is an OMC. I have purchased both engine and throttle used and do not have a manual for either. What possibly on the throttle controls the choke?

Pushing IN on the key switch activates the choke(Primer selonoid). If it starts fine cold, does not sound like a choke problem. Can you give more info about your starting procedure and any other problems that are occuring.How long do you run it before it won't restart, Ect?

I have run it for an hour. Shut it off for about 30 minutes. Then I tried to restart. The engine turns over but doesn't "catch". After three or more attempts, I can smell gas coming from the engine. I have not checked for spark.

Is it possible the coil is damaged or getting too hot? Will a car timing light work on the o/b to check for spark?

Yes a car timing light will work. It is an excellent way to check for spark.<br /><br />Ken

As Rick said, the pushing in of the key activates the fuel enrichment (read choke). Are you pushing in on the key when you try to start it? <br /><br />If so, you'll flood it.<br /><br />Also,<br /><br />The John/Rudes will act this way if you have a faulty needle and seat and/or float in one or both carbs.
