Good morning, my name is ***** ***** am I speaking with? I read what you wrote. Do you have a model number on the outboard?
Hi Keith. Got it. If taking the plug leads off made no difference then either that cylinder is not sparking or that cylinders carb is not flowing fuel. Start by changing the spark plug first and retesting. If it still does it, you would need to hook up a timing light to that plug wire and see if the timing light flashes or not. Flash means the cylinder is sparking, if there is no flash, that cylinder is not sparking. If there is no spark swap that ignition coil for a coil that is firing and see if the problem follows the coil or not. If it does, the coil is bad. If it does not, the CDI box is bad. If the timing light is flashing from the start then you do have spark, and because of that the problem would be that carb is not flowing fuel into the engine. Does that all make sense. I think that should do it but I work for tips so I do want to make sure you are happy with my service before you go. If you had a further question on the issue by all means feel free to ask. If not, Just in case you do not understand the way the website works (and some folks do not). You do have to put forth a positive rating in order for it to credit me for helping you. When ratings are not done, the website simply keeps your deposit and they will not credit me. The ratings box is located at the top of the screen. To rate, you must select the star you wish and also confirm it. Please let me know if you run into any problems or errors when trying to do it. If you do have a problem, or if you can not see the ratings box which is at the top of the screen. Please reply back "I rate Jason's service _______" and fill in the blank.
Please note that our question sessions never close out, so if you need to come back later down the road with follow up questions to the issue, you can do so at any time, even after putting through a rating.
Thanks in advance, and good luckJason
It only takes a few thousand volts to give you a good zap. It takes 20 thousand+ volts to fire off a spark plug. You getting zapped is different than a plug actually firing, which is why it needs to be tested with a timing light. (Or a KV meter if you want to get really advanced). On the butteryflies. Yes they all should be even, but that would not cause a cylinder not to fire. What causes a cylinder not to fire is a lack of compression, lack of spark, or lack of fuel. You have compression so that is good. The zap test isn't good enough, so spark will need to be rechecked with a timing light in order to tell you if that spark plug is actually firing or not.
You are very welcome Keith. Thanks again. -Jason
