No spark lawnmower

diamond_dave

B&Q 4 stroke lawnmower TRY3.5PLMA has no spark. It needs a new coil but I'm having trouble sourcing one. I can't find the engine maker suspect it's a B&Q own one. Any advise would be welcome - several online look similar but not sure. Would a Briggs one fit.?

Googling found me this.    https://solenttools.co.uk/product-category/spare-parts/bq/try3-5plma/ 

Do you have a bulb primer on your engine?  If the answer is NO then they have a compatible replacement.
If yes that isn't suitable... but they may be able to advise you on alternatives (or if you need to scap it).

Have you checked the oil level?

As if low will stop spark

Why do you need a new coil ? when you say it has lost its spark , try spinning the engine over with the spark plug out ,put the plug into the plug cap and hold the base of the plug against the engine body and check the spark.

I agree with you - but would advise using a stick or a piece of wood to hold the plug against the body.  Even though the plug cap is insulated, if you hold it in your fingers it's still possible to get a bloomin' painful jolt from it.

Well at least they will know that the ignition system is working

Thanks all for your comments. I did see that Solenttools had one but wasn't sure of the quality. As for the lack of spark I've been through the checks - new plug, check wires for shorts etc still not spark. The problem is that these cheap Chinese engines are rubbish and there isn't the spares backup like B& S engines. I could have got one from China but...
