Re: Who knew...?

Was there a gasket between the lower unit & the water pump housing, & how thick (approx)?

Re: Who knew...?

You can get a lot of air through a very small hole, I've had one almost completely blocked with salt/rust concretion in the top of the brass fitting at the top of the water delivery tube. I don't know how many Seagulls I've worked on, but I've only ever seen water coming out of the holes once before...

Re: Who knew...?

Grumpy try removing the water delivery tube & checking that it has no obstructions down the hole, with a length of fencing wire, it's not unheard of for a rust flake from the cylinder wall to drop down the tube & get stuck, as the water drains out of the cylinder after use. I've only worked on a cou...

Re: hybrid

Spent a lot of time in Henderson, Mclaren drive, a Pomme mate had a company there called Race FX, building race cars.
Then stayed in Henderson heights, until he moved everything to Hampton Downs.

Re: hybrid

Probably needs 10 mins under load, on the boat.

I thought you were out Henderson way, that would make the heads miles from you.

Re: hybrid

Did they have 2-stroke oil or were you using SAE30 motor oil? Chris

Re: hybrid

Grumpy what colour was the spark plug? Several of your country men have passed comment on your mixed fuel going off over the course of time, something that I've never seen in the UK, I'm told yours doesn't contain some of the bio stuff ours does. I've never seen separation & some of my fuel might we...

Re: Which seagull

That's a big boat (ton & a quarter?) with a lot of windage for a 40! Where do you plan on using it? Salt or fresh water? Take it for a test drive with a clutched silver century, or an ENFR, if that's not comfortable try a century plus or a Kingfisher. Post a pic of the transom, you might need a weir...

Re: hybrid

The spark plug colour will tell us how it's running (rich or weak). Seagull changed to the larger, more expensive 46N carb for a reason, as 40TPI so rightly said, logic says that reason must have been, higher power output. Change the fuel pipe if you want, but as the extended one is flowing four tim...

Re: hybrid

That's more than enough for wide open throttle under load. What's the throat diameter of your Villiers, measure with a 1/2 inch drill bit, it's either 7/16 or 1/2 inch. Silver Century cylinders are normally fitted with a 15mm Amal twin jet or a 16mm Amal 416, what colour is your spark plug running w...

Re: Reliability

It was a device called an Atom made in Australia, I think, that just replaced the points.

Re: hybrid

Chris if you look at the size of the needle valve fuel aperture & the fuel consumption per hour of a FPC at full chat. So if Grumpy lets us know how much fuel will flow into the float chamber in 60 seconds with only half a tank of head, we might be able to make an informed guess about if it's the re...

Don't damage your fuel tap before you know if it's part of the problem.

Re: hybrid

Good suggestion Chris! As a matter of interest Grumpy, could you measure the fuel flow? Just turn off the fuel tap after half filling the tank & ensuring the vent is open in the fuel cap, remove the float bowl & holding a jug under the the carb, turn on the fuel tap for one minute & let us know how ...

Re: Long distance Seagull trip.

I did just over half of peter's trip 20 years ago, when my lad was about 10 in a 15 foot Coleman Canadian canoe with a side mounted FPC, with a tent & sleeping bags, Swags didn't exist here in the UK. All was brilliant until we got caught in a thunderstorm just before Henley, 3 inches of water in th...
