• I have used “Shoulder of Shoreham” a couple of times, although they will probably want to sell you the whole wheel and not just the bearing – but there are plenty of bearing sales places if you google it – your bearing will probably be imperial rather than metric.

    After a complete rebuild a wheel bearing should be a doddle!!

    Best of luck

  • Re the statement above by hdtrust – Your engine is a 248cc RSJ (Ransomes Simms & Jefferies) which is centrifugal

    Question from a grey-haired old fogie – what is a centrifugal engine and how do they work? Is this the forerunner of the Mazda rotary engine?

    Hi uru33 – I had a twin cylinder Howard Gem and I manufactured a double plough(ridger) for my potatoes. I fitted it in place of the depth foot and used the tillers to soften the soil and help drive the equipment forward. I have very heavy clay based soil, so every little bit of forward motion helps. Unfortunately I sold the rotovator a couple of…[Read more]

  • Good day all
    Timing all fine now, tweaked it very slightly. The only problem is that it’s impossible to check the points with the brass cover on the points housing with the flywheel fitted – unless there is a crafty way of removing/replacing it that I haven’t discovered – any ideas??

  • Does the Monroetiller have sufficient power to drag this through the soil? I guess it depends on soil type – it might struggle in my clay based soil.

    In reply to: allotmenter posted an update @john-e-w Thanks for getting in touch unfortunately I’m near Newmarket so not anywhere near Sevenoaks which is such a shame as more information would have been invaluable – plus I’m […] View

    Hi Bob – for somebody that doesn’t know how to use the website, you are doing as well as I can manage. Newmarket is only an hour or two away from me – I used to work with the army at Thetford, so know the M11 quite well. My problem is that I don’t have a tow-bar, so have to rely on a friend who is going on a camping holiday next week!

    Is the…[Read more]

  • Wow! my dad used to have one exactly the same as in your picture – depending on your location, I wouldn’t mind having a go at restoration. I’m just outside Sevenoaks in Kent.

  • Now I have the rotovator up and running, the only problem I have is when I stop it after 45-50mins work and it’s nice and warm. It stops OK but in doing so it backfires quite alarmingly. Does that mean that it is too far advanced or too far retarded. I must say I’m not a fan of adjusting the timing by the placement of the flywheel on the tapered…[Read more]

  • Thanks for info Charlie

    Having posted my message on the forum, I then read some of the backdated newsletters, only to find that back in the day you were advertising “User Manuals” for sale. Is this still the case and if so could I purchase one please.

    Unfortunately I’m not really clued up on the new “digital speak” – what is a pm?

  • Good-day all

    I have just rebuilt (successfully) the Mk15 engine for my rotovator. Now I need to know about the oil requirements for the two (gear trains?) just in front of the tiller unit. How do you drain the emulsified oil out as there doesn’t appear to be a drain plug, and what oil do I refill them with (20-50??). I was also surprised that…[Read more]

  • Hi Charlie – the red paint laps over the edges of the engine plate – underneath it is a sort of “rusty grey”. Interestingly the plate is held on with two brass self-tapers.

  • Does anybody have a service manual/exploded diagrams for a Mk3 Villiers engine fitted to a Monro rotovator. I am just about to venture into the “rebuild world” and would like to have some idea of what I will be letting myself in for.

  • Hi Charlie
    It was a tad warmer this afternoon so I ventured into the garage. There is a plate on the engine cover that says:- Type S3 Machine No 034069. Is that the info you are after?

    Having taken the head off last year to find out how much play there was in the piston and noted that it said +40 on the top of the piston, you would think that…[Read more]

  • Thanks Chris
    When it warms up a bit I will venture into the garage and have a look. I thought the engine number would be the one you wanted.

    There was the number 15 just under the number I provided, so I assume that it is a Mk15 rather than a Mk12. However, it is a side-valve and I thought I read somewhere that the Mk15 was an overhead valve -…[Read more]

    Finding my way around the site. I went to pay my subs and found out that my “free” membership lasted until the end of March and I appear unable to subscribe. Great, except that I seem unable to locate any of the back issues of the magazine – maybe it’s just me!

  • Hi Charlie – I have a Monro tiller, I think it must be a Mk3 as it has a reverse gear lever. Everything works except for the engine(no compression). I have checked the valves and they both go up and down, but I can rotate the engine without any resistance. I note that it has a +40 rebore, is it possible to take it up to +60?
    Also could you give…[Read more]
