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 else’s 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 it’s posted at the end of someone else’s 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.

    Might want to explain this a bit more.

    The rest of that long sentence was a bit hard to understand as well.

        Checked compression, timing and dwell?

        How old is the Fuel? Filters been changed?

        When was the last time you changed plugs, plug wires, cap and rotor?

        This something new? Has boat performed properly before?

          its a boat i got from a friend . i have not changed the fuel filter . best that i know it has not been ran for probley 5 years or so. like i say it runs great in the yard it has new cap roter but no new wires or plugs. i did dump the fuel filter and it had sum trash in it. i disconected the line at the tank and put it in a 5 gallon can with fresh gas. i did check copression on all 4 cylinders they all were good

            Sounds like you have some work to do. Sounds like a carb rebuild may be in order.

            Also, never dump a filter and reinstall. That trash that didn't quite get dumped out made its way to the output of the filter and is now being sent to the carb. Always replace with a new filter when you take an old one off.

            What were the compression numbers?

            Points? Dwell? timing?

                Re: omc 2.3 cobra

                OK...I will ask these questions again one more time.

                Did you set the timing to spec?
                What were the compression numbers?

                I promise...I won't ask the same questions for the 4th time again!

                How did it run before you swapped out the points?

                    Re: omc 2.3 cobra

                    Is the timing advancing like it should when you increase RPM? Looks like you should have 34° total advance with 10° initial.
