Hi Folks, first post as an Egg owner here. I recently purchased the Ginny B from Edgar Batzel. A 1972 33 foot SF. The boat is in wonderful shape, and I intend to keep her that way. I do however have what is suspected to be a fuel starvation problem with the starboard engine. Can anyone tell me if there are anti-siphon valves installed on the gas tanks in this boat ?

I've already changed filters, and even the fuel pump, now I can't get the starboard engine to fire. Short of dismantling every link in the chain to isolate the blockage, I was wondering if it could be a simple as a blocked anti-siphon valve.

Thanks in advance !

Egg, it's difficult to explain, I should probably take a picture of the arrangement and then try to explain it. There is no separate line to the genny from either tank. It's physically connected underneath the valve that feeds the starboard engine. So, why or how would that have any impact on the port engine ? In my mind it shouldn't, but at the least I should probably install a cutoff on the generator itself, like there is every place else. There are petcocks everywhere, on the fuel tanks, on the manifold, before each engine fuel pump.

Also too, I read somewhere on Egg Forum pages, and of course I can't figure out where I saw it now, the starboard engine exhaust noise is significantly louder at idle than the port. Someone here gave an explanation of that in another forum, and offered a couple of suggestions as to what might be the problem. Do you have any idea's ?

At least you are isolating the source of the problem. So you are saying the gen is tee'd into the port engines fuel line? Or is there a separate fuel line coming from the port tanks?

If tee'd, you can always "plug" the gen fuel line and see if that helps.

Update: Rebuilt carb and reinstalled, all 5 by at this point, with one exception. Pulled away from the dock, both engines idling away. All of the sudden, stall on the PORT engine. Edgar told me he thinks, or was told that the genny may somehow be allowing air through it's fuel pump into the fuel manifold. Not sure how I'd ever verify that, and since there's no cut-off to the genny fuel source, I can't verify that. Anyway, I selected the port fuel tank for the port engine, and restarted, spent the rest of the day cruising quite successfully. I was very pleased with the performance. Took her up to 4000 RPM at right around 30 mph according to the GPS.

Fuel quality is an issue today, doesn't store as well and can funk up the carb easy, see it all the time in my marina.

Use the boat a lot and it will keep the fuel fresh. The ones that sit seem to have the most problems with the carbs.

Let us know how it goes.
