Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old threads or hijack existing threads. Old threads of a technical nature are like a library book, Please do not write in them.

2. Old threads should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís thread (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new thread of your own.

4. If you have a question for the original poster (OP) and the thread is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old thread.

5. By starting your own thread, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • 1972 Evinrude 50

    I recently got a 1972 Evinrude Lark 50. In general, it runs very well. It has plenty of power at the top end and runs pretty well at lower rpms. The only problem is with idling. Even with a fast enough idle in neutral to make the gears clunk when engaged, it will slow and stall when put into gear if I don't immediately tweak the throttle. I have tried adjusting the carbs and synchronizing the ignition, but it still stalls after a few seconds in gear. If I set the idle while in gear, the engine runs way too fast in neutral.Any ideas?

    I have a 1975 50 hp rude "Sizzler" that I bought this year. Same symptoms as yours. After reading my Clymer manual I deduced that I had a fuel delivery problem. I replaced the fuel line, connectors,6 gal. tank, primer bulb and rebuilt the fuel pump. Total was under 50 bucks if I remember right and all is fine now. Except that I trashed the prop second time out. Oh well, live and learnMike

      Thanks, MikeThe tanks and line are new, but I will check out the fuel pump. I suppose if the pump is not efficient at low rpms, it could do this, and still be able to put out at higher speeds.Vin
