The major issue with this machine is an unknown engine problem that caused it to stop/seize up, the previous owner suspected a bearing in the engine.
So I set about stripping the engine.
First task was to remove cowling, exhaust and inlet etc.
I have found if a magneto is suspect it is far easier to change coil, condenser and points all at the same time. A more expensive way to solve problem but it does mean everything is new and should give years of trouble free running. Also only requires setting timing once.
Benjamin the links I gave include other threads if you go to the home page. As others have said Zeus tables are a must have along with thread gauges. I have a book which details many other threads including German and Swiss variants of metric, it can be a minefield.
Alternatively the throttle cable needs adjusting at top of carb, if too long it allows slide to drop to far and engine will stop. Adjusting length has same effect as opening throttle with lever ie it lifts the slide and needle.
mayfield, if you are having problems renewing your membership follow the help link ‘Problems? see the help page here’ on the homepage this will give guidance and alternative links.
