Andrew , if Peter Giles is in the UK there would be a few sources for info . I do remember some years ago there was an article about Stuart Turners , a collection of different models including a small gen set . It was in ''The Stationary Engine''[ SEM] magazine.May be a letter to the mag.

I have a list of ranges of engine numbers. No two engines, whatever model have the same engine number. There were various engine number ranges for each engine type or types.

Your engine number relates to a Model N with serial numbers 6000-6999 manufactured over the period June 1932 to April 1933, therefore your engine was almost certainly built in 1933.

If you have have any specfic info I be interested. I have some ads and articles but nothing specific to your 1933 Model N. As you can see from the engine numbers there were a lot produced over that small period but the numbers dropped off with only 382 being produced over the period April 1933 to June 1935, after which it went out of production.

I guess you saw the pics of my Type N marine posted here earlier this year? When I enquired on Fairways, who can usually date S-T engines accurately from factory records, I was told simply that the N was produced in fairly small number's from 1932 to 1935 and that they had no further information (or spares availability) for the model.

However, while this may be true for the marine version, I believe it was introduced earlier for stationary applications. For instance, a 1930 S-T lighting plant catalogue shows what appears to be an N in basic ungoverned form on the smallest sets. I suspect that when the S-T engine went 'up market' with the introduction of the P4, with it's full width crank and separate cylinder block in 1928, it left a gap in the market for a smaller cheaper 'entry level' unit. Enter the N, with overhung crank and cylinder en-bloc with crankcase like the old P3. The N was only to be a stop-gap though and went out of production after the introduction of the R series in 1934 as it would have competed directly with the R2. Just my opinion you understand.

Very nice set by the way. If you decide to restore it, bear in mind the lack of available spares - I broke a piston ring and had to get a replacement made. Also there is a special trick for separating the big-end which will not be immediately obvious.

Your engine was sold SIET engineering Ltd
as an N2 version sold on 24th January 1933
Hope this helps as mentioned we have very limited spares for this engine but we do have the original Stuart green paint

Further to Peter Ogborne's comment about the Stationery Engine magazine, there is a list of reprint artciles that I belive is published every few months which lists sevberal Stuart articles. Unfortunately, I've just recently subscribed and have lent all my issues to a friend so can't be more specific at this time.

However, he should contact a few English machinery clubs, in view of the number that have been on display at various rallys - pics on the net via Kim Siddorn

Hi i have had my engine running,but only for a couple of minutes,then it backfires through the carb and fades off, if i flooded the carb it would pick up and run again, i cleaned the main jet but now it will only keep running with aid from the dynostart,it also keeps flooding and backfiring through carb and exhaust.

Back in historic times about 1950 my wife and I with our infant children lived in Thames Ditton near Kingston on Thames, UK and there was a boat livery at the bottom of the road where couples would come in the evening to rent a small boat with a Stuart inboard of some vintage. It amazed me how reliable the engines ran with absolutly no problems as far as I could determine. My experience with two strokes at that time was they were cranky and took a lot of tender treatment to get them to perform. These engine simply started and ran and were really very quiet on a cool summer evening. I don't know what the secret was but Stuart seemed to have solved the problem enough that there were no broken romances as far as I could tell from balky engines. The boats went out under power and returned under power so I guess one must assume they performed. Just another useless footnote to history!!.

Peter ...your N type looks great , i am envious!!
Your running troubles. The carburetor looks the same as the type on my R3M , very little to go wrong . It sounds like there is starvation of fuel .But then you say the carb floods, Is the float ok ? no small pin size hole, this could cause the flooding.A obvious question, is the small hole in the petrol tank cap clear? Also try adjusting the air cap ,thats the knurled brass cap with the holes in it,normal setting is about a quarter of an inch screwed out.
Sorry i can not help further but keep us posted.

Peter...I have the same problem with my R3M.After running for some time the plug oils up. It is just idling [at a rally] I have been reducing the amount of oil and have met with a much better performance.As you may know there is an accumulation of oil in the sump and of course this carries over to the combustion chamber ....good for lubrication but bad for spark plugs.
I have a small cock on the sump drain so at a rally i open it now and then to drain the excess.

Peter...I also have a Stuart Turner R3M. I run the fuel mixture at 50 to 1 as specified in the ST manufacturers service manual supplied with the engine. I found the best oil to use has been SAE 30 'running in oil'. I found this is available at the Motor Traders shops. It is the closest thing I could find to the old original SAE30 oils and seems to burn well at the lower temperatures that these marine engines run at, minimising oiling up of plugs.

I run my engine in a small boat and the fact that it is usually running at half to 3/4 throttle under load helps as these engines seem to like working with a bit of load on. It will idle well for long periods and always idles and runs better after a hard run with no oiling up problems.
