The timing light idea is a good one,as you know when it's going to stall you can watch the flashing light, as it stalls you should still see the light flashing until the engine stops
As it's got a carb what type of choke does it have ? manual/auto.

Lexi,
would there be enough slack in the HT leads to fit one of those miniature neon HT spark testers. I ask all of my customers to carry one in their car so that if they do ever have a problem with starting or running of the engine, they can fit it in line between the coil and plug and determine whether the fault is due to lack of fuel or lack of sparks. As you've already surmised, the voltage required to ensure a spark will be higher when the engine is under load.
Ken.
( Picture shows an HT tester fitted on a coil, with a healthy spark.)

Was wondering that if spark was weak enough at a certain time to stall under load...but start immediatley.could that not be detected somehow at that moment. What about connecting voltmeter or timing light to spark plugs while running. Take the reading when running hard , then when it stalls start it again and watch reading. I know when i put that lever into forward it is gonna stall. Does anyone think this may tell me anything.

Thanks guys. Actually Si you may be on right track with condensor. That is a capacitor and the capacitors are in the CDI module.......sealed for life. Choke is manual. The timing light and the spark jumper that TD shows, will be the next moves. Thanks for photo mate. We used to rig something up with a little plastic tube. The HT leads cannot be removed from coil or I would have replaced leads anyway. The indicators would have to be attatched at plug end. I know a guy with same engine but I wouldn`t want to borrow CDI unit after finding out that it is 200 quid to replace!

Will keep plugging away.
