Thank you to you both. Do you have Diesel Bobs contact number by any chance?

Welcome to the club; as a recently joined member myself I can attest to the fact that there is much help and support from a friendly bunch on this site.
I look forward to seeing your finished BMB – Looks like quite a challenge to me!
Ben.

Collected the re-made rotor cover this afternoon. I am really pleased with the exact copy of my cardboard template…… It fits perfectly!

Added some oil to the sump and a squirt of fuel……

Have now rebuilt the engine using governor parts from the donor engine. stripped, primed and painted it. Repaired the exhaust, rebuilt the carburettor and fitted the new air filter.

Thanks!
I did my best to keep this under my hat…… It all came about after the Tractor World Autumn event, I contacted T&M as I was under the impression there would be photo’s of the prize winners in the following magazine. However my enquiries revealed they were cut from the final edit…… I asked if it were possible to have copies sent to me? I was then put in touch with Peter who asked if I would like to write something about our hobby, how I got into it and a little bit about me??? And that is that!

A good write up indeed, Darren will be charging for autographs now !!

Made a start inspecting the MK12 engine from this machine yesterday. I wasn’t too concerned about the internals as I had previously had the head off to check the piston and valves etc. I had also had the engine running with just a squirt of fuel, enough to make it run. However, I wasn’t prepared for what I found when I pulled the sump off……. 2 rather large components sitting in the oil at the bottom! these bits were the governor gear and its shaft……. I had previously noticed the governor arm was broken where the spring connects, but didn’t associate that with anything more serious. It would appear that the governor arm has broken whilst the engine was running, the engine has then ‘run away’ ungoverned causing the counterweight gear to self destruct! Thankfully nothing more serious than a few light scratches to the crank lobes has resulted, the crank itself, con rod and piston skirt are all intact and serviceable. Thankfully I have a donor engine I can cannabalise for the required parts!

Thanks Charlie – that’ts helpful – will do. I am hoping that the mag was timed when it was refitted after the refurbishment

[vhgmcbuddy]

Can someone tell me what oil and quantity should go in the gearbox, also where the filler,drain and level indicators are ?
Regards
Shaun

Thanks a lot – I’ll give it another go at the weekend. I have a multi-meter so am going to try and test the Mag.

The guy had rebuilt the whole thing (or so he claims…) so I was hopeful that the engine is in good shape – but I just havent had the time to really concentrate on it – hopefully the weather stays dry for the weekend and I can have a more methodical approach to trying to get it started.

Thanks both – I guessed as much – I saw that there were several versions of the cap and that one didn’t seem to have any sort of mechanical fixing….

So I just strip away a bit more of the HT lead sheath to expose some more copper, then wrap that a couple of turns around the sheath to create more of a friction-fit and connection, push it in, tape it up and test away….

This is a second Gem i own, together with a 350. All of them have come to me for less than £300 in total… and I really want to get one of them working!!

I’ll no doubt be back after I’ve done some initial testing on the Mag…

One observation – when I turn this Gem over – I can feel some resistance and there is the sound of aspiration from the engine, but it isn’t particularly difficult to turn over. There is a decompression lever, which when I squeeze that, it doesnt really seem to make any difference to how hard it is to turn – not much of a struggle to be honest.

I’m really not sure as to whether this is usual – does a JAP 600cc engine turn over relatively easy??

[vhgmcbuddy]

And here’s the machine. In too good nick to actually use!

If anyone has any pneumatic tyres/wheels for a Gem they’d like to sell please let me know – the cast-iron wheels just make it too difficult to move about.
