First Carburettor Strip down and Rebuild...

I really should have photos on this, but I was up to my bits in... well little bits.

My Suzi DF 2.5 was quite unwell. She has only run for a bit, but she's spent 2 winters sitting in the shed. At first I could not even turn her over, but (with the kill cord removed) I spun the prop and then pulled the starter, rinse repeat until things freed up. I guess it just took a while to get oil all around it.

Then whoopee, she started.

But only with full choke, any attempt to touch the throttle, or take off the choke killed her dead.

Googling arrived at the realisation that the carb was probably gunk city. So a quick look at youtube and this video amongst many gave me a place to start.

One €10 can of carb cleaner, and a couple of aluminium foil trays to put the bits in, a set of socket spanners, and a few screwdrivers (including some quiet small ones for the jets) and it was time to open things up. (Nitrile gloves are good too, carb cleaner fluid is pretty harsh.)

There was less gunk than I expected, and I was starting to loose faith that this simple cleaning would make any difference, until I started on the jets. Remove and clean them one at a time, then you don't have to figure out which one goes back where!

The two main jets were fine, but the pilot jet was clearly not. It's hidden away under a screw - how does anything get in or out? Clearly something does. The pilot jet was completely blocked. No light at all. I left it sitting in carb cleaner while I had lunch, then gently poked it with a very fine needle. Eureka. I saw the light.

Then the "put it back together game". As I disassembled it, I'd "looked back" to see how it would go back together. Pictures might have helped, but for the DF2.5 it's not that complicated.

Moment of truth, Choke, Pull, she lives.
Kill the choke, she dies. Oops, not enough throttle. Try again.
Choke, Pull, alive.
Some throttle, kill the choke, she's still running,

I wound the throttle in and out, and she revved up and down, Just Peachy.

I'm not sure what that would have cost me at the local Suzi Marine supplier, but it would have been a trip out, and another trip to collect, and I can't imagine getting away with less than €75?

But now I know a little more about engines. I suspect that this will be an annual event given how tiny the pilot jet is. Pictures next time....

How a Carb works...

Sailing in Clare

After spending so much time building a boat, I have learned that it's much easier to steal an hour or three to work on the boat, than to steel an entire day to go sailing. But on this trip to Clare with the family, a day presented for me to go sailing, by myself.

The sea is a very different place, with tides and proper waves. At first I found a lovely place to launch from, Bell Harbour, only to find it dries for a good portion of the tide. Also, as you come out to the sea proper, the entire body of water funnels through a small channel. Not a place to be in a small open boat unless you are within an hour of high tide.

Ballyvaughan however has a slip, which is good at all time of the tide except the lower end of the springs. It's quite steep, but there were a few local lads, who were kind enough to help me getting The Lady Caroline down, and back up again later.

Now I have built a boat, and sailed it once or twice, but sailing is still a learning thing for me. I really must remember to close the self-bailers before launching the boat.

For single handing, I need to add some sort of rudder lock. I also need to learn to heave too, but given that there was a short steep swell, and at times I was close to picking up a bath full of sea water over the side, it seemed the wrong time to try that out.

My little Garmin showed my speed, which I tried to use to see how setting my sails affected things, but with the swells and the gusts, it was quiet hopeless.

TLC did just fine. I did not fly the Jib, since I am still learning, and she does not point so very well without it, be we managed.

On the way out, when I hit the worst of the swell, my course was taking me directly parallel to the waves. This was a quite a lot less than fun, so I fell away a little, and then headed back up into the wind so that I was crossing the waves enough to keep things stable.

On the way back I came in along the coast a little more to avoid the worst of the swell, that put the shallow sand banks between me and the rest of the Atlantic.

My plans for the next trip are to try heaving too, try anchoring, and if I can sort out oars before then to see how I manage at rowing a little. TLC has a 6' beam, so she's won't be an easy row, but we should be able to manage.

Sailing In Clare

"The cold rain makes it hard to see where the barren rock that passes for soil meets the bleak grey cloud. If this is summer what fell shadow must be cast on the soul of any man exiled to spend a winter in Clare?"
