It has always been rumoured that they were used on grass airfields for towing fighters out on to the runways but other than the picture Neil attached which I believe is from a museum in Holland, I have never seen any photos of MG crawlers in use. I have seen quite a few photos of crawlers painted in military livery including American army. I have a copy of a Ransomes book which details what went on with ransomes during the second world war it shows lots of photos of ploughs and crtawlers being made alongside artillery guns and aircraft parts but no aircraft towing.

Well, when I rebuilt the Engine I set the timing as per the instruction book. Everything is tight and I have no reason to suspect that it has changed.
However I am prepared to try anything as it is no use as it is.
The annoying thing is, sometimes I can start it on the first attempt. It then runs well with plenty of power, no backfiring or stuttering.
I will check the timing again, also the points and the condenser.
It might be a worthwhile exercise to fit a set of timing marks to the flywheel.

Thanks Charlie
I’m slowly getting them all sorted out over winter. If it keeps going this well I’ll have to buy some more machinery, otherwise I’ll have done all the fettling jobs that were supposed to keep me busy when I retire!

thanks for thinking along: looked at that, but No, it’s not like any ordinairy oil seal: Both axle and outerpart are actually rotating with the same speed, but the outer part is tilted and ‘wiggles’around too. A lot like a CV-joint (homokinetic joint) or a Rzeppa joint. the seal acts like a bellow.
Honda patented … special part, NOK AZ7882E … and google isn’t my friend this time (tried that of course).

Your numbers indicate that you have a points ignition 5HP engine that would have been fitted with a 397398 coil which has been replaced by a 397358 Magnetron electronic coil that does away with the need for the points and condenser and may be fitted without removing the flywheel.Roughly £40 + vat)for a genuine BS one.
As per per my earlier post, you may well be able to pick up a good used one from a engine scrapped for some other reason. What you need is Magnetron coil from a 5HP 13**** series engine (either vertical or horizontal crank). Before you go shopping, carefully measure and note the distance between the coil supporting pillars on your block and check it against any coil that you are offered as there are fractional differences between engine sizes.
A quick measure on a 5Hp block in my workshop (dark and snowing!!) is approx 59mm BUT PLEASE CHECK FOR YOURSELF.

Is this part a rotary shaft oil seal? If so, the size you have listed should be available from most bearing/oil seal stockists. One can be found at the following website: https://simplybearings.co.uk/shop/p26834/35x75x8mm-Nitrile-Rubber-Rotary-Shaft-Oil-Seal-with-Garter-Spring-R23-/-TC/product_info.html

There are many other online oil seal suppliers.

Hope this helps.

a warning for everyone: Do NOT buy at SparesBB, this is a fake company skimming your data.

That interesting, if I’m reading it correctly it was manufactured on 19th April 1979 ? and its 13 cubic inch etc etc.
Can you tell me for that information what ignition coil I need ?
Regards Ian

Hi Wristpin thanks for your reply, I couldn’t see a number where you mentioned but there is this number 006063 on the data plate, is that the one ? there is also a number stamped on the engine which I cant read yet as its quite rusty where someone has previously rubber the paint off. regards Ian
