I have a 4 or 5 year old yahama 25 hp 4 cycle engine that starts and runs fine for about 30 minutes ... then the engine quits running and has fuel running out the overflow from the top of the carb... Anyone have ideas what's going on here ? Is it somehow fuel presure related ? Any insights into this problem appreciated ... Thanks, Todd Traver

Check the float valve. It isn't closing as it have to when the float bowl is full. A bit strange it happens after 30 minutes.<br /><br />Drain the float bowl in a clear or at least clean bottle. Look for dirt. If there is, clean the whole fuel line. From tank to carb.<br /><br />/Bear
