thank you wristpin you are
thank you wristpin you are correct it is the electric start model sorry forgot to add that part just spit balling here but it does have a electronic ignition module would that be a good first port of call it does turn over with the battery well once the spark is back ill start on the carb any idea of the cc of these units thanks again
I suppose that I ought to
I suppose that I ought to know the cc but if I ever did, I've forgotten it now. The only book that I can find says that the engine is a Mitsubishi G221P-LSA and googling that number I found this

Knowledge at a price!
I'll have a further look in my archives but not very hopeful.
thanks wrisoin for all your
thanks wristpin for all your help much appreciated yes that knowledge does seem pricey for that engine b&s could have been tempted but back to the b20 i bought a ignition module a nova and she was up and running thankfully not the coil ran a bit rough but striped carb down cleaned it out and it runs and cuts fine altogether best £28 ive spent including the module with try it out through summer get it in the workshop over winter and decide if to change engine to a b&s when i have more time many thanks again for all your help
I believe that all the
I believe that all the Mitsubishi engined machines were electric start so there was a fair amount of charging gubbins in the magneto but the ignition coil was powered from the flywheel and didn't need the battery to function.
The other issue with that engine was that the carburettor was very sensitive to dirt and fuel quality and was a pig to rescue once contaminated - definitely an ultra sonic cleaning tank job.
I'll see what I can find paperwork wise later but my suspicion is that only a genuine Mitsubishi coil will fit.
Edit
The Atco parts books have not produced much of use to you; the engine just being shown as a lump rather than in detail. As yet I haven't unearthed anything showing the parts breakdown for the Mitsubishi engine but there is a recoil start version shown in the 1990/2 parts book.
