Re: 1965 merc 1000 100hp Boggs Down?
martyt: The float that you salvaged from the other engine may not have been a large improvement because of its age. The plastic floats from the days of early polymer chemistry are marginal at best. When you try to float them in gasoline to see if they're any good, it's hard to determine the answer. Newer, oxygenated auto gasolines have lower density making the problem worse-if you're using them in Ohio.<br />Can you get a new set of floats? And, are the fuel filter screens installed in your carb inlets? If the screens aren't there, then your carb cleaning was very temporary after replacing all the fuel lines and shaking lose decades of crud buildup. If the sceeens are there and don't have any holes or crud buildup, they're good as is. You can tell for yourself if the carbs need to be cleaned again.<br />I found on mine that new needles and seats didn't look any better than the old ones. That leaves floats to be fixed. If you'd like proof that the floats are the problem before buying them(prepaid to be sure), try having your first mate pull the fuel connector from the engine while bogged down at 2000 or so and then hang on to something. If the floats are the problem, it will soon pickup, maybe big time!! If it does, shut it down IMMEDIATELY, NOW, and consider this your proof. (Remember, some of it will be running very deficient of oil for these moments.) If you have trouble getting the floats, let me know. Also, let us know how this turns out.<br />I know this old beast is trying your patience, but, hang onto it. As I recall, the acquisition price was pretty good. After long neglect, it takes a little while for all its needs to surface. I'm sure-and mellowyellow will back me up on this-that you'll find this old straight six easy to live with. Especially, if you budget for plenty of gasoline!!!
