Webb Diplomat 350 Petrol Lawn Mower stops running 10 minutes

I have the above Petrol Lawn Mower, I need a manual or service manual or Maintenance Manual for reference for the machine.

Also, if anyone has advise as I would like to service the machine myself so information on how to perform an oil change on this lawn mower sharpner the blades, and any other service needed on the lawn mower.

Currently my lawn mower stops running after about 10 minutes and will not restart.

Anything would be appreciated

Many Thanks

Karl

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! )

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

My problem is with a Webb H12R-A manual lawn mower which has the blade set on the lowest setting possible but doesnt cut the grass


Are the blades turning when you lower the deck? If not, your belt may be slipping or it's off the pulley. Once you lower the deck and lift your foot off the the brake / clutch it should engage because the slack is now taken up on the belt, so slipping, belt jumped off or belt stretched out.

I changed the oil in my Craftsman Lawn Tractor 24HP Model No 917-288320 and the "change oil" message on the LED screen won't go away. Is there a reset button somewhere?


Below is excerpt from the owners manual:

SERVICE REMINDER/HOUR METER
Service reminder shows the total number
of hours the engine has run and flashes to
indicate that the engine or mower needs
servicing. When service is required, the
service reminder will flash for two hours.
To service engine and mower, see the
Maintenance section of this manual.
NOTE: Service reminder runs when the ignition
key is in any position but "STOP". For
accurate reading, be sure key remains in the
"STOP" position when engine is not running.

It should reset the 2 hours has expired

What would cause the lawn mower to stop running when not out of gas? If you give it a few seconds and restart it it will run again for awhile then stops. I have noticed if I pump the primer a couple of...


Try using non-ethanol gas. It's death on small engines. Starter fluid gives it a boost if higher octane. Have a reputable repair place clean out the gunk, then use good gas. Best of luck finding non-ethanol. Boating marinas carry it.
