Hi all<br /><br />I will try and give you all the facts in point form below, then explain what i have done.<br /><br />*I dont know the year of engine, (dont know how to tell), but it looks like the 1973 to 1991 models, and is on a 1985 Wellcraft.<br />* System has a filter/water seperator.<br />*Starts sometimes first try, sometimes takes ages to kick over.<br />*Will only idel sometimes. The engine fires and does not fire then fires again, with about 1/2 second between each cycle.Vrmmm Vrmmm etc<br />*When it starts, it will rev at high rpm, but sounds rough.<br />------------------------------------<br />What I have done.<br />* Drained fuel, filled with new fuel.<br />*Bypassed fuel hose system, with clear hose from another gas tank (to monitor for water/air.)<br />*Drained fuel bowls.<br /><br />I am happy that I am now running good fuel in a good system up to carbs.<br />I feel it sounds like an electronic problem.<br />At the moment the start switch will not even kick over the engine, even with 12 volts to the starter.
