I am using champion RC12YC and using regular unleaded gas. I guess if I'm to use premium, I'm going to need to lug it to the boat in 5 gallon jugs...

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! Could be the carburetor. I've had this issue too many times. I chose to take off the carb, break it down completely and clean it out. Moyer Marine's A4 guide is very useful. Brians/v Rekofa The Blue Whale1979 C&C 34Baltimore, MD Dr. Brian C.

The fuel pump ought to be able to overcome that. Can you drain the trap? I would drain or remove the trap and try it. Try a new P-trap designed for the purpose. Might want to check the operation of your fuel pump. I just put my boat in the water for the first time and had a similar issue. 5 minutes and then stall. Starts back up after a short wait but won’t run for longer than about five minutes. Sort of ran if fully choked. Turned out to be a broken electrical feed to my electric fuel pump. Hard to believe how long it ran without a fuel pump! I guess gravity and vacuum will do part of the job, even through two filters.

Okay so no wind today... I pulled up to the gas dock, topped off water and fuel, loaded up and away we went. Motor was running great! Fired up left dock, motored away. After about an hour she seemed to be running out of gas. Stutter ed and stalled. Five minutes later, after seeing sail, she started right back up. We sail back to our home mooring. I pull the filter on the sepertator, looked clean as the day I put it in. Then I thought, maybe the vent is plugged... well, it wasn't plugged but it is routed with a trap and that trap was filled with fuel. Would this have been enough to starve the engine?
