I made the mistake of running out of gas, and then after adding fuel, the engine faltered, would only run with choke out and/or at idle. Any power, even in neutral caused the engine to stall. I have a 1976 Pearson 28 with an Atomic four. When I purchased the boat two years ago I replaced the gas tank with a Tempo plastic 16 gallon tank, put in new gas lines, primary filter, fuel pump and in-line 2 micron secondary filter, and overhauled the carb.
I believe the Marpac primary filter is a source of most of the crud in the fuel. The filter is only 9 month old, but when I took it off the bracket the top inside metal structure was badly corroded and when I dumped the contents of the filter into a bucket there was a lot of brown stuf as well as some "gritty" substance. I took off the in-line filter, blew it out backwards and got more crud. Then I took off the carb and got more crud. Doesn't appear to be much water and the little there might be was in the primary filter. I don't need to use the engine very much, normally just to get out of the slip and down the fairway and around the pier, only a few 100 or so yards. I've put more time on the engine in the slip than underway just to make sure it gets run under load every week. I used less that a tank of gas in the last year.
Is there a better primary filter that won't introduce rust into the system?
Since I do not use more that a tank of gas a year, should I add a couple of gallons a month and keep the tank full, or run the tank to almost empty and then fill up? The old gas/condensation issue.
I have replaced both filters and cleaned out the carb and the engine runs very nicely, so the problem was clearly contaminated fuel.
Thanks for your suggestions. It would be nice to have a regimine that assures clean fuel all the time.
