ParticipantThe last time I worked on an MT was about 40 years ago, but I think that you are on the right track. The drum may need a bit more persuasion.
However, there is someone on this forum, Trusty220, who may be able to impart practical knowledge.July 22, 2022 at 6:37 am #39499wristpin
ParticipantThese would be made from a special alloy as they are the wearing part of any cylinder and if you get it wrong it reflects badly on the whole machine
The difference between the characteristics of various manufacturersā blade materials is very apparent when regrinding cylinders, both in spark colour and sound. Two examples from domestic machines come to mind – Hayter Ambassador cylinders seemed to be hard and brittle and it was usual to find damage to the ends of the blades. On the other hand the material used in the Atco DeLuxe 14,17,and 20ā machines of the 1960s to 70s was very soft and quite badly buckled blades could be hammered straight and reground with no ill effect. Again noticeable with bottom blades, some being quite soft and responding to a quick skim while others needing a well dressed wheel and and lots of coolant.
The bottom blades from Saxon Triples (now Baroness) used some rather special alloy and really needed a āgreen wheelā. In the day those blades were very expensive but outlasted those used by Ransomes several times over.
Re-blading cylinders may be a thing of the past but a while ago I bought a very cheap Ransomes Marquis for āSpares or repairsā as it had an āunblemishedā grass box but interestingly it had a very good cutting cylinder in terms of lack of blade wear but the quality of the welding suggested a rather amateurish re-blading job.July 20, 2022 at 5:13 pm #39496wristpin
ParticipantThe old thing is slowly giving up its secrets. I presume that Allett have a record of the original buyer but is there any information of its life in service? Re the Ransomes identification letters on the spirals, is it dangerous to suggest that Allett may have used complete Ransomes cylinder ?

ParticipantAlways a good idea when an engine has been standing and before you try to turn it over, to remove the plug and squirt in a good dose of lubricant, wait a while, then gently turn it a few degrees back and forth. If it moves feely, go for a gentle rotation, then refit the plug and proceed as normal. A good precaution against ring damage etc if a bit of rust has formed in the bore.

ParticipantI knew that I had a few Gutbrod / Motor Standard parts books etc but had forgotten where they were – blame either age or heat!
Anyway if you post the model numbers that you have, I will see whether I can match them up.July 18, 2022 at 1:07 pm #39472wristpin
ParticipantThey were either re-badged or made under licence Gutbrods – hence the German connection.

ParticipantIt really has been some time since I updated this story but I havenāt been slacking. The main piece of news is that Iāve had a minor disaster with the fibreglass lid; it had many dents and scratches which I was filling with stopper (a very fine filler used for small imperfections) but when I went to flat them back to blend them in with the rest it proved impossible without rupturing hundreds of microblisters. It looks like somebody in the past has repainted the lid with a high-build primer/filler; this was coloured orange. The green paint was applied over the top of the orange primer but because the surface preparation was not good enough at the time, the primer/filler has lifted in hundreds of blisters and lifted the green topcoat with it. What this meant in this case was that when I flatted it down it left lots of orange spots in the green paint- not a good look!
Thatās why those who do a proper job on fire glass bodied cars , Charge what they do. Looks like the chaps who last repaired it or even those who made it skimped / omitted the gel coat. Normal finishing products for steel bodywork are not usually suitable for fibre glass.

ParticipantToro did get back to me with the expected answer no idea
Sign of the times, Iām afraid . Most manufacturers seem to rely on dealers and distributors to field and answer technical queries. The last time I needed some tech info from Hayter, I ended up talking to a very polite young man in Belgium with little product knowledge. A far cry from when Hayter had a roving tech in a high top van who called on dealers and conducted a mini service school on such matters as setting up a 21 or Osprey final drive and clutch.

ParticipantB&S Flo-Jet Carburettor problems
The teflon washer referred to is part number 391413Had a bit of an issue retrieving this, so may be duplicated! Two better than none!

ParticipantI must have swept up a good few balls over the years but have never considered trying to save them so I canāt be much help there Iām afraid. Having been āin the tradeā the total cost of a repair was a balance between the cost of a guaranteed to work new component, and the workshop charge out rate. In the case of the ratchet assemblies it was no contest. I appreciate that you are working āpro bonoā for a friend but we had a saying that āno one thanks you for a cheap fixā – if it works the saving is forgotten, if it fails, the attempted saving is forgotten also!
Paint. Briggs do/did list aerosols of their various standard engine colours but I canāt remember anyone ever ordering one. For a tidy up of black engine components Iād suggest an aerosol can of Barbecue paint available from most diy stores.July 8, 2022 at 10:59 am #39437wristpin
ParticipantI wish i could sort the carb. as easily!
A two piece flo-jet prone to flooding ? Thereās a couple of wrinkles that may help.

ParticipantSomeone told me that ordinary gasket paper would do. What do you think?
Not sure that āpaperā would do the job. Most packs of assorted gasket material contain some fairly tough stuff that resembles that used in oem gasket sets. What ever you use it will be worth āfacing offā the cylinder head on a surface plate to remove any imperfections or even any warping. That will give your new gasket a fair chance of sealing.
It occurs to me that there may be specific BMB information on a stationary engine forum or there may even be a specific user group on Facebook .July 6, 2022 at 10:57 pm #39419wristpin
ParticipantHarrier 51 ?? Are you sure? Would have thought 48 or 56 – maybe. Can you find the machine ID number that pins it down to the exact model. Usually three digits and an alpha on a rectangular sticker on the opposite side of the body to the height adjuster. However those split corrugated rollers use the same ratchets for the 48 and 56. Itās usual to replace the ratchets as an assembly, not repair them. They can be time consuming to get apart and most commercial repairers resort to oxy acetylene or a thin cutting disc on an angle grinder. Hayter used to offer the two ratchets and the concertina dirt shield assembled on a shaft as one part number. In fact they offered complete roller assemblies as it was not unusual for the teeth on the rollers that engage the ratchets, to be worn away, and the whole assembly being floppy in the centre, even with new ratchets
