Hi all,<br />Unfortunatly I am back for more help. i copied other previous posts below for info. So it seemed like a switchbox for sure as in posts below. I bought a new box and cycilinder 5 still does not fire.<br /><br /><br /> posted 05-05-2006 05:59 AM <br />--------------------------------------------------------------------------------<br />Hi all,<br />When I go to wide open throttle with my 115 sometimes I only get to 4,000RPM then after a short time something kicks in and the engine goes to a full 5,000RPM on its own. Other times it goes to 5,000 right away. Any suggestions would be appriciated. (coil, switchbox.....?)<br />Thanks <br />========== <br /> Clams Canino <br /><br />Lieutenant Commander <br />Member # 36683 <br /><br /> posted 05-05-2006 06:23 AM <br />--------------------------------------------------------------------------------<br />Could be a 1/2 fouled cylinder kicking in after it clears. <br /><br />But try spark testing all 6 too. Just hook a timing light to each plug wire to verify power. Then clean the plugs with carb cleaner and a terri rag.<br /><br />Past all that suspect a carb.<br /><br />-W<br /><br />--------------------<br />C.C.

It would repeat whereas carb problems should stay cleared out once cleared during the "boating season".<br /><br />Wouldn't hurt to decarb and put in a new set of plugs.<br /><br />Mark <br />--------------------------------------------------------------------------------<br />Posts: 854 | Registered: Dec 2005 | IP: Logged | <br /> <br />bobnteri@optonline.net <br />Cadet <br />Member # 57871 <br /><br /> posted 05-06-2006 09:40 AM <br />--------------------------------------------------------------------------------<br />Hi all,<br />Thanks for the replies. Checked spark with a timing light as recomended, I have NO spark on Cyl's 2 & 6 at idle. Is there a way to check coils or switch boxes. All wires on switchboxes are new and they are on correctly.<br />Thanks again <br />--------------------------------------------------------------------------------<br />Posts: 10 | Registered: May 2005 | IP: Logged | <br /> <br />Laddies <br />Captain <br />Member # 49545 <br /><br /> posted 05-06-2006 10:27 AM <br />--------------------------------------------------------------------------------<br />Those 2 cyls don't share a trigger winding, so it's not a trigger. They do share a switch box and stator windings. Without a DVA it's not tpo easy to test, you may use a OHM meter to test the stator windings but the results are not as accurate as a DVA. Lacking a OHM meter one can aways change the wires one the 2 boxes and see if the problem stays with the box or goes with the stator wires, but either use new plugs or a spark gap to ensure its not bad plugs <br />--------------------------------------------------------------------------------<br />Posts: 3677 | From: northern michigan | Registered: Sep 2004 | IP: Logged | <br /> <br />bobnteri@optonline.net <br />Cadet <br />Member # 57871 <br /><br /> posted 05-06-2006 02:12 PM <br />--------------------------------------------------------------------------------<br />Thanks,<br />did spark test again when engine was warmed up some. #2 cyl not firing and #6 is. Next i switched switch boxes and #2 fires and #5 does not. Would this be proof that the switch box is bad??<br />Thanks again guys,<br />Bob <br />--------------------------------------------------------------------------------<br />Posts: 10 | Registered: May 2005 | IP: Logged | <br /> <br />Laddies <br />Captain <br />Member # 49545 <br /><br /> posted 05-06-2006 04:15 PM <br />--------------------------------------------------------------------------------<br />99% chance Bob
