Does anybody know how to adjust the gap between the ignition coil and the flywheel on this machine? The ignition coil is located at the inside of the flywheel.

Just to update.
I took the carb off one more time to thoroughly check everything again and all seems well. Unfortunately, when re-connecting the copper petrol pipe I managed to strip the thread where it connects onto the carb.
I also changed the spark plug (used the once from my mk 1 clifford – has same engine as the allen scythe) and it seemed to run and rev much better despite petrol leaking out of the stripped thread!

So this brings up a few questions.
1. could a wrong or ‘bad’ spark plug stop the engine from revving properly?
2. What spark plug should be used in an Allen scythe – the one that it came with had k-17 on it, but the ground electrode looked very worn and thin.
3. What is the ‘fix’ for a stripped thread in the carburetor?

Many thanks

Hi Ian and Anthony
Charlie will be able to date accurately from Monro records, but judging from mine, fairly early one , 1949/50 I’d guess.
The carb isn’t like mine but SIMARs were fitted with AMAL carbs. I might be tempted to check timing and magneto before fiddling with carb. I have the timing info. I can send it if you pm me your email address.

Just to enlarge on the governor situation. When it cuts in it is a very distinct sound as the engine in effect four strokes or may be even eight strokes – once heard, for ever remembered, but not what I would class as rough running, as soon as the load goes on the engine starts to sing.

Thank you as always for the useful replies.
I have checked the exhaust port which seems fine and I also ran it for a minute with no exhaust – still the problem persists.
I took off the carb and the main jet did indeed look blocked – cleaned it out and I could see light through it and thought that would solve it, but still no change.

Yes, I was going to ask about the govenor, as I read about this and noticed it when setting the points. Will try it under load (I have a big patch of stingers and brambles to try it on) and let you know if there is any change under load.

Thanks, Ben.

Hi Andy
You have to book in advance. I have contact phone numbers, I’ve pm’ed them to you. Great show, well worth a visit.

My guess would be a blocked main jet in the carb.

Also worth having a look at the “other end” – carboned up exhaust port or even a choked muffler.

My guess would be a blocked main jet in the carb.

it has to be the ignition coil- no more testing required.

Hmmm a dangerous assumption – if I may say so!

For a start, does it have a low oil level cut out? If so is it working correctly or is there a safe level of oil?
Then if it has an electronic trigger rather than points and condenser there’s a better chance that it is the trigger (igniter in Nippon speak) rather than the coil.

But there again you may be right!

I was interested in the opinion of somebody who worked on Kubota engines and there specific characteristics.
