Re: Piston Ring Gap

Thanks for that advice. In terms of sealing, your experience would suggest that bore finish is as important, if not more so, than ring gap. I take note and will investigate honing/glaze busting. I think the theory is that oil is trapped in the small scratches to improve sealing and thus compression....

Piston Ring Gap

I am in the process of fitting a replacement block onto a FV and re-using the original piston. The piston ring gap is 0.031 which I think means that new rings are required. Is that correct?

With new rings what should the gap be set to?

Thanks

Date Stamping

I was looking at the letters and numbers stamped on Villiers flywheels on FVs and wondered whether some of the numbers were date codes. Would 12-9 be December 1949? Would 7-50 be July 1950? The other stamping, which is common, is R63/A61/M. A part number perhaps? If they are dates, I would guess tha...

Re: Biodegradeable oil

There is Castrol Biolube 2T. I have no idea whether it is suitable for our Seagulls. Perhaps, somebody who knows could comment. I am sticking to TC-W3 until it has been resolved. Here is an extract from Castrol's spec sheet:- __________________________________________________________________________...

Re: Seagulls as the greenest motor on the water

David, You have certainly collected a great deal of information. Thanks. As you indicate, there are two applications:- 1. Gear boxes. It might well be possible to use a food grade mineral oil. Whether it is worth the trouble and the potential risk to the gears is a moot point. One important aspect i...

Re: Brass Tank

Oyster's thread about canted tanks got me thinking. (to nearly quote!). In actual fact it got me examining my (FV) canted tank. It is the same carcass as my LM/LS tank as identified by Charles. I should have realised that before. Of course all the fittings are in a different position, but dimensiona...

Re: Brass Tank

Thank you Charles for the info that it came from an LM or LS. I wouldn't mind the rest of the outboard - preferably the LM version - but that is a real long shot. More sensibly it should be reunited with an LM or LS which is tank less. Any takers? I presume Charles, that your very early SJM hasn't g...

Re: Seagulls as the greenest motor on the water

I am interested in this 'food grade oil'. What exactly is it? What is it called? Where can one get it? Is it just a matter of filling up the gearbox in the usual way but with SAE140 biodegradable? Is that its complete description? What about adding it to the petrol. Why and how does the mixture need...

Brass Tank

Some advice please. I have a brass tank which appears different in shape to the 40 series ones that I am familiar with. I would like to know what it came off and its date. Dimensions are:- Fore and aft 4.5". Compared to 5" on others. Height 3.1" Compared to 3.4" Length 10.45" compared to 9.8" End pl...

Re: Little Model Forty F (1949/50)

Here is a photo of F201 with the 223 Amal loosely attached. Visually it looks ok and compares very well with the photo that Charles P took of the other one, which is shown in the fourth post of this topic. HPIM0109.JPG However this Amal (model 223/001) of mine is far too big. I think that the correc...

Re: Little Model Forty F (1949/50)

Thanks for that. I have just got to be more alert on looking at e bay. I sent a msg to the chap selling this one, to confirm that it has actually been sold, which it has. I have found a good site giving details of the Amal. I do not have the address at the moment. I think it is britcycle.com. Do you...

Re: British Seagull Industrial Engine

Thanks for that input, Charles. I didn't want to set a hare running; just curious about what this chap read out to me, and interested to hear from you that there is no evidence of a Seagull Industrial engine.

British Seagull Industrial Engine

I was speaking to a guy at Amal Carbs, and in conversation he mentioned a Type 52 Amal Carb (with a 0.328 chock dia) was fitted to a 40cc British Seagull Industrial Engine.
What was a Seagull Industrial Engine?

Re: Original tiller grips

I have one or two, but fitted on, for my purposes, the wrong brass tiller. I have not worked out how to remove them without damage, so that they can be fitted onto another tiller. Hot water soak doesn't seem to work.
