A4s rock!

Wow! Such an honor! This means a lot, coming from you guys. Thank you Bill and Don, and fellow Afourians. I'm just another guy struggling to learn his engine. The help I have received on this forum...

Larry, welcome to the Atomic Four world. Yes, definitely get a tachometer. There is a reason why it is often the largest gauge on the boat. I can't imagine not having one, and not knowing the RPM. ...

My guess is that you have water in your tank, and your water separator filter, if you have one, got so full of water that it just sent it downstream. That is why those filters have drains in the...

Most sailboats have a spare block and rope. If you attach the block to the battery and use twice as much rope, your load will be cut in half pulling it up from the ground to the deck.

Yikes!

Your report of an open screw hole on the bottom of the carb woke me right up. Joe is correct. Sounds like you need a scavenger tube fitting in that hole. Otherwise you'll be leaking gas into the...

I see from the excellent photo that the cable is being pinched because the clamp is holding it at an angle, instead of on the perpendicular. If you rotated the bracket that connects with two screws...

If you rebuilt the fuel pump, I found this old jpg file showing how the pump can be reassembled incorrectly. Maybe this happened to you. Note the 'incorrect' orientation of the bar connecting the...

I changed to an Indigo from a 12x5 two-blade. It is in an aperture with much more clearance than your photos. I get better thrust in reverse. After a haul- out, I get 6 knots at 1900 rpm, with vacuum...

The bail on my pump is usually mostly loose and flopping around, except I get resistance at the outboard or port side of its motion. The 'up' side, as you describe it. The bail pumps more or less gas...

marvelous

I use 2 oz. MMO for 5 gallons of fuel. That is what Marvel recommends. That is a ratio of 320:1, which is less than 1/3rd the maximum Dave mentioned. I have a pint bottle of MMO, which has marks on...

Diagnose, but go ahead and grasp the straws anyway.

Definitely, check for spark to begin with, but I suspect your problem is fuel related. That to me is the usual problem. The engine ran fine for 30 minutes, then hesitated and shut down, which to me...

bale away!

As Ken will probably tell you, just prime the fuel line up to the float valve using the bale. The bale will go loose at that point because the line is pressurized. A fuel pressure gauge is helpful...

Cleaning the seat is the usual fix. The question remains, why did the needle stick? I think if you use MMO in your gas, this is less likely to happen. I also think ethanol softens the rubber, but I...

Make sure when you replace the distributor cap, you replace the rotor as well. They wear at the same time.

save the baby!

My evidence that ethanol is bad is not scientific, only anecdotal. I stopped using ethanol, and the orange goo in my filters and carb didn't return. That really happened. Maybe by that time, the...
