Hi all,

I've picked up a Suffolk colt lawnmower today, unfortunatly its not producing a spark at the moment.

Just wondered if anyone has any experience of these motors, any advice very welcome please!

Also looking for manuals (long shot i know)

Behind the flywheel, you will find a set of points. I expect that they will need cleaning at the very least.
Take of the orange/ red cover, and you will find find the flywheel. This has a "half moon" shaped plastic  cover in it which can be prized out. you should be able to see the points opening and closing as you turn the flywheel to the left and right. Fully open should be around 18 thou-20 thou, I think. You might find that you need to clean up the points' surface with some fine emery cloth.
If you need to adjust them, this can be done through the small hole, just loosen the setting screw and move the points set to give the correct gap, tighten the setting screw and check the gap.
The older engines used to print the correct gap on the "half moon" cover.

Very good advice from Graham . One thing i have found works well on points .
Is a nail emery board . Just a gentle rub does the trick .

Would also suggest "painting" the open points with an artist's paintbrush dipped in meths after adjusting and emery-cleaning to remove any traces of oil or grit particles (it will evaporate in seconds.)

I have found in the past that electrical contact was still not being made after cleaning due to either slight oil contamination of the feeler blades used to measure the gap or tiny particles of abrasive preventing proper contact.

The whole thing sounds like an extract from the log of The Star Ship Enterprise to me.... but my Dad says a splosh of meths helps! 

I'll stick to my bike
