Hi Danny, What is your electric fuel pump doing in all of this? is it a pulse type?
The reason I ask is after relocating and isolating my pulse style pump I could no longer tell what is was doing, so I moved it back to the under cockpit sole supported location. Here I find it will give me a reassuring pulse (through my feet) like a heartbeat. It beats faster with more load, predictably and will go very fast, more like manic, if there is no fuel... air leaks etc. as it tries to maintain set pressure.
Cheers, Russ

Okay,Given all the discussion, I've decided the next step, as it is really the only thing I did not replace, is to buy a 5 gal outboard engine gas can and run the engine with a brand new gas can and brand new gas. My gut is leading me back to the tank and the pickup tube.I think this will eliminate the entire existing gas system and either show me the light or eliminate it from the investigation. Of course, I won't be able to test it all out until Saturday.If the Gas can does not do the trick, I'll swap the carburetor again... I'll go home and clean that up tonight so I have it at the ready. So, should I, if the gas can does not prove to be the issue, continue on the 5 gal OB tank and swap the carb or go back to the existing tank before swapping out the carburetor?Danny ---------- Original Message ---------- From: Robert Abbott via CnC-List <[email protected]> To: [email protected] Subject: Stus-List more atomic 4 issues..

He can chime in and tell you the story.I have an old (est. 50 years) Lawn Boy lawn mower.....for years, it started the first pull but after it ran for a while and you shut it off, it would not restart. Replaced the coil, problem solved.Keep working at it, you will find the problem.

Alright, the saga continues.We went for a sea trial Sunday after the changes, i.e. Vent line cleared, filters changed, clamps tightened. The engine ran great all the way to Cuttyhunk. I probably ran it about 3 hours. Two of those hours I ran it a little harder than I normally do after having read Don M's reasons for having black sooty spark plugs. I thought my problems were solved.On our way home from cuttyhunk, We motored out the harbor and decided that, because the wind was a little light, we would motor home to run the engine some more. 50 minutes into our ride home, the same thing, only a bit slower. the whole, slow, stall happened over maybe a minute or two. Some sputter, then run normal, a little more sputter, then normal and then a slow stall.We then sailed home and into the mooring field. This is actually a benefit of the engine troubles, I've been a bit intimidated about sailing onto the mouth of the river due to the current and very tight channel flanked by shoals and some pretty ominous looking rocks. I've now had to sail into the harbor twice over this last weekend. At one point we were probably doing 4 or 4.5knts through the water but only 1 to 1.5knts over the ground fighting that current. On one side of the boat it a big, rocky cliff and the other shoal. it was a little adrenalin pumping! Anyway, the approach to our mooring was dead, head to wind, along with the current in the same direction, I lost forward motion under sail and started the engine. She started right up and we motored onto the mooring without incident.So, safely moored, I pulled the vent tube, it was clear. I then went below and pulled a spark plug and it was all black and sooty again after maybe 4 hours running time.I used the Moyer rebuild kit on the carb that is on there now. I'm not sure but, I think I changed the main jet to the moyer recomended one at that time. I think it came with the rebuild kit.My earlier idling issues seemed to have been solved by swapping out the carb that came with the exchange engine for the one I rebuilt off the original engine and had just sitting around as a spare. I think what I would like to do now is, clean up the carb that came with the exchange engine. and swap them back out. I'll then replace the plugs and run it some more. Unless you guys think I should maybe try another path forward.Danny P.S. Cuttyhunk was Amazing! No virus found in this message.
