Webb Diplomat 350 Petrol Lawn Mower stops running 10 minutes

The 'DIPLOMAT' series of WEBBs is bad news, its NOT a WEBB! Webb were swallowed by qualcast-atco-suffolk, who dunped Webbs tooling, & dressed up punches & commodores in thin disguises, dumped the briggs & stratten engine for their own alloy job, & charged a rip off premium for the Webb decals!
The qualcast suffolk alloy engine suffers from a WIPAC electronic ignition unit. As it gets old, it fails, sometimes completely, sometimes as it warms up. Once cool, it works for a while again.
Not too hard to replace, but hard on the wallet, £69 genuine, £40 fake! On the whole its not too bad an engine if cared for & oil changed often. better to look on ebay for a cheap used HONDA engine & transplant! R-E-L-I-A-B-L-E !............I did! ( £35 honda gc series, 5,5hp! )

Hi There
Did this problem get solved - I have a webb 300 Diplomat and it starts and runs fine for a couple of mins and cuts out and then like the other guys mower won't start for a while. Any advice would be great

It sounds like fuel starvation. Check that the fuel tank cap is vented
