I got stuck at sea yesterday and had to get towed in. Here is a synopsis of the situation.<br /><br />We went 10km and then had to stop for 5 mins (which turned out to be 2 hours!) The motor ran fine all the way out but would not restart. On the previous run we had loss of power under load which led to stalling. We were able to restart but only after many attempts<br /><br />Some history<br /><br />1. Problems started after I closed vent on fuel tank (didnt know about this - and still don't know what difference it makes)<br />2. At the same time I put a spacer on the end of the propeller (which I doubt would have any impact)<br />3. First probs were losing power when under load and then eventually stalling. This was intermittment. To solve it I would stop the motor and restart. It blew a lot of smoke but then ran fine.<br />4. Restarting was difficult on these occasions. Often took a long time and when it did fire it blew a lot of smoke.<br />5. Motor has started reasonably well when cold, however the last few times it has been a bit more tricky<br />6. It has new spark plugs<br />7. Fuel is about a week old and mix is good<br /><br />Any ideas???
