A little help
Went to the boat today and did some engine work. Took a few pics to get some feedback on. The distributor has a cap with two screws (no clips), does that mean something? The distributor looks like EE, right? The rotor is a little pitted, but the inside of the cap looks good. Fairly new 8mm wires. Coil looks good, and has 4.1 ohms across it.
I'm working on giving it a tune up and a rewire. The engine was running but hard to start. I plan on checking the timing after the rewire and tune up. I tried to take the plate under the rotor off, but it was lifting the center rod up too. So I left it in place till I could get more info of what is going on. I am open to any comments, questions, or advice about what you see in the pics or what I've said. Also the tube above the flame arrester is missing. ? |

Check to be sure the choke is closing all the way.

The antifouling paint is doing a good job keeping the barnacles off the rotor.
Hard starting: I would be thinking carburetor before timing. |

SPN, the first thing I would do is eliminate the "trailer" style plug especially if doing any kind of a rewire. This will possibly eliminate any weak connections to which these plugs are notorious and pretty much worthless after corroding a bit.
RE the distributor does the centrifugal advance "pop back" when twisted? If so just replace the cap and rotor while being very careful as to the firing order of the wires. A fresh set of plugs (gap @ .040 with the EI) and be sure all connections are clean and well snugged. As per John do be sure the choke is completely closing!! This is a must for good cold starting. Check the "spark" and what you want is a spark that is crisp and blue that will pop at least 1/4". This will confirm the coil and the EI. Dave Neptune |

I do want to remove all the wires (and there are a lot of them) and that plug before I clean the engine. The engine electronics should be isolated from the house electronics, other than charging possibly. I did not want to mess with the centrifuge until I did more research. That plate would not come out without removing it. I will check the choke and adjust if necessary as I work my way around the engine during this inspection. I just bought the boat a month ago and I am in the process of renovation it. The blue paint on the distributor was on there when I opened it up (I thought it might be marking something). I was surprised to see EE, everything else on the boat is from 1976. That is the first upgrade I have seen.

Also called a "Slash Tube"
You can get one from MMI here on this site. Although I searched the online catalogue and couldn't find it anywhere. (Bill?) Maybe give Ken a call and he can get you one. You can also, of course, make your own.

Thanks for the info. I'm a new A4 technician and an old sailor. This is my forth sailboat and first A4. The other sailboats had outboards and I got used to working on them. I will be going to the boat on Wednesday to do more inspecting and cleaning. The cart with MMI (so I get the right part) is getting full with the things I need, but I want to work my way to the other side of the A4 before ordering. I will also take more pictures. Personally, I like seeing other peoples A4's for a reference and comparison (plus I am going to need some before and after shots).

If you do not have a copy of the Moyer Manual then add that to your "cart" also unless you've done that already.

Tenders: "The antifouling paint is doing a good job keeping the barnacles off the rotor."- so witty for so young you are
