ParticipantThat’s a VERY wise decision , only my personal opinion , but I’m not a great fan of the cheaper coils that you have on yours. The new ones sold by either Villiersparts or Meetens are, I would say actually better than the originals. They’re not cheap , but in the long run far better , in terms of value for money, and most importantly performance.

ParticipantBarry , looking back again through the pics you have posted , it seems the wrong coil has been fitted , it looks to be a “short” coil in place of the correct “long” coil. In all my years of fiddling about with Villiers engines , I can’t say I’ve ever encountered anyone doing this before, when taking into account both coil types are still easily available
However provided the correct bushing has been fitted , I can’t see any reason why it would not work. The correct coil is a 1030.
With no disrespect to the previous owner , this is more evidence that it has been messed with , by someone who , shall we say , is not quite fully switched on.Moggyjim , flywheel is held on a keyless taper , set timing to 3/16 BTDC.

ParticipantI’ve lost count of the number of times I’ve said on here that multimeters are no good for properly testing coils , they need to be done on a proper ignition tester.
It’s not always easy to tell from photos , but judging on the colour of the coil , it appears to be a later modern replacement , have you cleaned and reset points and tried for a spark , making sure all the wiring is correct.Andy.

ParticipantMy apologies ,I should have said Straight non detergent, Angus is quite correct. Under no circumstances use any form of synthetic oil in you 25c.

ParticipantSTRAIGHT 30 grade , Morris oil is of the highest quality.

ParticipantThe linkage you refer to is the freewheeling system , in the position in your pic it is in freewheel , in other words it can be easily wheeled about without engine running. Slightly and gently lift the tab and move it towards the gearbox and your machine will be in drive , you may have to slightly wriggle the machine from side to side to align the internal splines , but this is common , under no circumstances force it.
Your cylinder bore , although not easy to tell from the pics , appears to be OK , is there any undue “piston slap”??.
Again from the pics it seems to already have had a new coil fitted , so assuming the conenser is OK , I see no reason why you shouldn’t have it up and running fairly soon.The bane of the 700 was the air filter , if you intend to use it regularly , make sure your hose and joints are all in good order , and that the filter is also , taking care that it seals properly inside the housing. I think I’m right in saying (Hortiman may well confirm) that a Diesel grey Fergie oil filter will do the job as a relacement.
Luckily I haven’t encountered this problem with mine , as it has the very rare and unusual oilbath air cleaner system.Keep us posted with your progress.

ParticipantIf you are taking the Coleby on I have some 25A spares for the engine.

ParticipantCharlie , I’m confusing the issue , the machine I’m referring to is the pic Benjamin put up , which is the Hoe and Mow , it’s been on that auction site for some time. The topic machine is quite obviously a homemade affair.

ParticipantRegarding the head being on wrong , I wouldn’t have thought it would have done any significant damage , just that it may have run a little hotter. Parts and instruction manuals are always available on that well known auction site , BUT, none that I have seen cover the butterfly carb that is fitted to the 700.

ParticipantChalie , I think we’re talking about the second image , which appears to me to be the Mayfield hoe and mow.

ParticipantCongratulations , the 700 is a superb piece of kit, and yours appears to be a fairly straight example. The Engine is a Villiers Mk28b , 353cc twostroke. Unfortunately engine “internals” are EXTREMELY hard to source ,I’ve managed to accumulate a few over the years should I need any for my machine, most of the carb bits are just as rare , ignition wise , no problems.
Looking at yours it appears to have been tampered with to some degree , the cylinder head has been put on the wrong way round.
Let us know of your progress and what parts you think you may need.Andy

ParticipantI can’t recall the proper name or model for it , but that is a genuine Mayfield product.
Andy.

ParticipantI’m with Charlie on this one , it certainly shows signs of being a homemade conversion , although I’d say the handles are Westwood.

ParticipantGrand job Alan.
Thanks for all your time and help.
