Re: Fuel Problem Need Expert Guidance
Hi,<br /><br />I had THE EXACT SAME PROBLEM and I can tell you that these guys ARE on the right track. REBUILD or REPLACE your carb. More then likely, you have the same very hard to find problem I did -- quite simply, the float is STICKING OPEN and you are FLOODING the engine out. (Several embareassing tows because of this problem)<br /><br />If you choose to rebuild the carb (its an easy one) you MUST make sure to SET THE FLOAT CORRECTLY!!! <br />There are TWO settings, NOT just one. <br />You will first set the level (how high the float can go before the incoming fuel is shut off) <br />And then you will set the FLOAT DROP (Extremally, Unbeliveably, Completly, and TOTTALLY IMPORTANT!!!!!!) Almost everybody forgets this one -- and its the cause of your current problem. Thats what the silly little tab on the back of the float is for (It hits the top of the carburetor and prevents the float from falling to far. Yours probably corroded off.<br />If the float can fall too far, IT WILL BIND, which means fuel just keeps coming in (thus why you run for a few minutes, THEN start to surge, THEN die). Also, thats why its at WOT -- at WOT, the fuel in the bowl drops significantly, and then comes back up. Letting it sit for a few hours gives the extra fuel time to evaporate.<br />When you put the new float in, AND AFTER SETTING THE FLOAT LEVEL, make sure it CAN drop far enough, though, or you will backfire and then die at high RPMS because you will be getting too little fuel. The actual spec is in the rebuild kit paperwork. (I used the sierra brand kit and it even had a little diagram to show you how to set the float).<br /><br />Just to restate, THE FLOAT SETTINGS are the MOST IMPORTANT part of the rebuild (its a low force moving part -- remember, moving parts fail first -- especially low force ones)<br /><br />Also, if your boat runs a little rough, think about a fuel / water seperator ($25 in sierra brand, comes with bracket and filter). Made a HUGE difference in mine, AND eliminated the white powery corrosion build up inside my carburetor. <br /><br /><br />hope this helps
