Instructables

sounds like you may have a bad coil. you getting gas but no spark if its sputtering can cutting out or it may just need re gapped

Make sure the gas cap is clean and vented

Has probably broken flywheel key ..... putting it out of time

SOUNDS LIKE YOU HAVE BAD GAS YOU MAY TRY CHANGING YOUR GAS

Sounds like you tilted the unit enough to cause the float in the carb to open too much and therefore, the needle valve inside is stuck.
Remove the bowl and let it resit itself and then re install the bowl. If that doesn't work you may need to purchase a new kit for the carb to get the needle valve. If you find a small minut ring around the face of the needle valve replace it. That's why it's gonna leak. Good luck

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! )

You may want to check the gas cap to see if it clogged with dirt. If the gas cap is clear, you more than likely have a carburetor problem. If you need tips on carb. cleaning, feel free to ask.
