Did you ever figure out what was causing your fuel problems?
Tom - I have the theory that my fuel problems were caused by ethanol cleaning fuel system components and sending it downstream. This is based on the color and composition of the crud, brown and crumbly - not white as would be the case if the particles were teflon. Dave Neptune suggested that my secondary filters were not of sufficient capability to handle small stuff and acting on his advice I have added the Moyer Marine 7-10 micron units from the catalogue, in addition to the recirculating system. I will be adding the threaded rod support for the assembly as recommended by Russ, and further suggestions and comments are much appreciated. Regards, Hanley

Hanley, I initially used teflon in my fuel line fittings too, and when I had to bail on a sunset cruise with the captain when the engine wouldn't run without choke, and instead take home and break down/clean out the carb, I am pretty sure I flushed a piece of teflon out of the main jet. I immediately removed all teflon and went to all Permatex. My carb is going on 26 months now without a cleaning. Granted, I probably only have 40 or 50 hours on it since then .

Incidentally, a marina in Key West, FL proudly advertises on a big sign at the end of their dock "NO ETHANOL FUEL".

here is a pic of what I got out of the bottom of the carb.

Shawn,
My family and I are recent transplants to Florida (Panhandle area), and I was surprised to find that many if not most marinas sell non ethanol fuel. I'm pretty sure it's unique to Florida. My previous marina sold it, as does our present marina. They do a lot of business with people buying gasoline for their small engine machines -- not just boats -- for the same reason Capt. Hanley mentioned. Don't tell any Iowa farmers about what's going on down here!

Talking Cobbling Along the Road

Components gathered from various "possible" pouches on board. The rod is 3/16" bronze threaded for 10-32 NF. The collar is an old 5/8" bronze nut the original use for which is long forgotten. The bracket is a spare VHF masthead antenna mount.

My wife says that I am the king of repurposing items from their original intent. Clearly I have been bested in this case. You must have some time on your hands, good work.
Wait 'til you see the hardtop dodger I'm making from an old fiberglass truck topper. True!

See any green flashes?

Hanley, if you ever sell the "Destiny", I'm pretty sure only an afourian would know what all your gadgets were for.

I hope you are writing an owners manual for her.

Hanley-

I'd like you to take that setup to some "big box" type store and ask the clerk if he could please find a replacement for it...just to see the look on his face!

Actually, this is becoming an issue for me as old age looms on the horizon. More and more often I find myself asking, "...how'd I do dat?..."

Shawn?

Shawn, I'm perplexed as to how a chunk like that could get through. Can you describe the particle at all?

Hanley, you need a hobby! Have you been running yet with the finer filters? That's a lot of plumbing and it sort of violates the "KISS" rule. Perhaps it is Destiny's destiny to be a "RSR" lab. I most certainly hope this works well for you. Careful with the cobble, I don't want to see/hear that you find bits of teflon in the carb .

Lightbulb slight hijack!

Dave, that bit I am pretty sure was a piece of teflon tape..it actually felt more like a booger.

If I recall, at the time, I only had the Racor filter mounted on the bulkhead & had not installed the MMI in-line filter yet. Even if I had it installed, there were lots of opportunities for teflon to break loose at any of the screwed in barbed fittings downstream, including the last couple where the hose goes between the mech filter to the carb.

That is my theory anyway.

As you've noted before, we usually don't find the culprit as it gets washed out with the carb cleaner..according to my thread from 2009 this just happened to fall out of the bottom of the fuel bowl when I back flushed the main jet.

Thumbs down Teflon & fuel

Shawn, you would be suprised! I have done a lot of carb work over the years, mostly modifying for performance apps. The most common thing I found in carbs that were a problem were bits of teflon tape and it came from anywhere in the fuel system and could get anywhere in the carb.

That is why I recomend Permatex #2 or second choice liquid teflon on any fuel fitting!!!!!

Dave - The Atomic 4 is my hobby. I have run with the finer filters at the dock but full field testing remains. I became a violater of the "KISS" so long ago I couldn't find the way back if I tried. As for the teflon; I'm hoping it couldn't get thru a 7-10 micron filter, but we shall see...

I go to Home Depot looking for some odd bits and get cornered by the help. They say " what's it for?".
I say "a boat thingy I'm making".
They say "what thingy".
I say " I won't know 'til I find the right materials"

That's when they walk off as soon as I look away.

Just gimme some stuff, and I'll make some thingys, OK?

Question Topper (side bar)

Hey Russ, I'm interested in your hard cover. I've been contimplating one for a while and my dodger is about shot. What are the truck topper options, is there a site or are you searching in scrap yards? I have some wood cut to form up a "one off", however cutting and tweaking an existing form may be quicker . I'm planning on tinted flat panel auto safety glass and the "center" front panel will open.

Perhaps this should go to a new thread, as a few may be interested.

I believe there's an article in a recent issue of "Good Old Boat" on building a hard dodger.

Question Fuel System Plumbing

Installed a fuel pressure gauge and ran the system. Pump pressure is 4 psi but I opened the "re-circulator" and reduced it to 2 psi. Engine ran fine at the dock up to 1500 rpm. Does anyone have information as to what is minimum acceptable pressure?

This response is based on what I think, not what I know.

I'd say any pressure capable of filling the carb bowl will do as long as it keeps up with your consumption. At slightly less than a gallon an hour it isn't much. Since the pressure reduction is past the tank draw and filter I think you're over the hump where pressure (or vacuum) is needed. A polishing filter could be an issue though.

I've been working with another listmate on an automatic fuel bypass system (concept complete, parts purchased but not yet installed) that is expected to drop the pressure at the carb to 1 psi. We will see how it works and post the results.

Thumbs up Preassure

Hanley, 2 psi should be fine. As I recall the supply preassure for the zenith is from 1 1/2 ~ 4 psi, it doesn't take much to pump a gallon an hour. You would be beter off with low preassure than to much. My mech pump works at around 2 1/2 ~ 3 psi and I have no starvation issues. If you wind up needing a bit more preassure, which I seriously doubt, plase a restriction as near the "tee" as possible and that should divert a bit more preassure to the carb.

Have you thought about the return stirring up the tank when the fuel is low? This could get the tank cleaned out a bit but carry a couple of extra spin-ons!!

The tank I am using as the "working" tank is the original which has a bottom drain - it has the best shot of being the cleanest. But I will have extra filters (all types) on board. I do have complete pressure adjustability with the ball valve in the return line.

Hanley: Based on what I have read if properly propped the A-4 should turn 2400 to 2500 rpm with the direct drive and 3000+ for the 2 to 1. Remind me of what your set up is, prop/reduction etc. Dan S/V Marian Claire
