Suggest JasonB has a look at the following website - http://www.saving-old-seagulls.co.uk/i_d_your_seagull/102_models.htm Lots of info on old-fashioned outboards including line drawings but could not see one with dimensions but I'm sure contact with the website could elicit the desired information.

Not heard of that before, will look it up. Thanks for the suggestion.

Thanks for all the responses, decided to try with a slab of polycarbonate first, see how it goes and if the problem still exists then further options will need to be explored. Chatted to a friend who experienced similar problems with a 1/2 scale Onan flat twin he built, he used polycarbonate and...

Timber no good, needs to be threaded M5 for the carby mounting bolts. Thought about Corian, also looking at polycarbonate which may have sufficient heat resistance for the temperatures likely to be experienced.

The hole for the pump pulse is there and operates well. Not starved for fuel while cold, runs up to full revs no problem.

Phenolic material would be ideal but hard to get at a reasonable price. Smallest piece in 10mm thick would be 300mm square at about $60.

No, the piece is moulded to incorporate a transition from the round carby throat to the oblong intake port. Trimming down the existing would upset this. Also the threaded holes for the mounting bolts do not go all the way through so cutting it back would reduce the thread engagement too much to...

Having problems with a Walbro carb mounted on a modified 25cc 2-stroke brushcutter engine. Due to space constraints the 25mm thick hard plastic carb adaptor won't fit so the carb is mounted on a 10mm thick aluminium adaptor with thin paper gaskets. After about 2-3 minutes running the engine dies...

Thanks for that. As I said, pepper was not something I was inclined to try, I prefer the 'fix it properly' method too.

My dad used to always say to add some ground pepper to the water if there were any small leaks as the pepper would get trapped in the hole and swell up thereby sealing it. Never tried it myself but he seemed to think it worked.

ZA-27 zinc alloy has good wearing properties and is easy to cast and machine.

Have you checked TEA Transmissions at Tiaro in Queensland? https://www.tea.net.au/ They have a fairly extensive range off the shelf including plain steel and hardened and ground. I've used their budget range and had no trouble machining them. Don't know how their prices compare with what you...

Interesting..... There are a number of people in Australia making diesel heaters for caravan/camping hot water and heating. Typical examples on this site amongst others: Home Maybe they would have some details you could adapt? Maybe you already know all about these?

O.B.Bolton (Bolton Scale Models) is/was an Australian distributor for a number of established steam and i.c. engine designs as well as having designs of their own. They are now known as E&J Winter but their website at Model Engineering still recognises the Bolton heritage. They mostly deal in...

Shoe laces? Would be strong enough and hard-wearing, and the newer synthetic ones have a little bit of stretch in them too so would possibly make it easier to maintain tension. Not sure how you would join them. Superglue for the cotton ones, melted ends pressed together for the synthetic ones?
