What is spark plug gap on unidentified pressure washer?

their 196 cc 0.028-0.031 in.

The recommended spark plug gap for a Homelite 2700 PSI pressure washer with a Champion Eco 322 spark plug is 0.030 inches.

but in my opinion, It's always best to consult the owner's manual or contact the manufacturer for the most accurate and up-to-date information regarding the proper spark plug gap for your specific pressure washer model.
good luck

It should be a Honda GC160 engine.

OEM sparkplug is a NGK BPR6ES @ .030 in. gap

Check spark plug is getting a spark and spark plug electrode gap

HI Franceen, with the information you provided I can only suggest you go on line type in the brand name, model and serial number of the engine on your pressure washer and perhaps you will get the specifications there.
If it is a small one cylinder engine tell me what brand name and model it is & I may be able to give you some better info.
for now you can try .028"- .034"

The spark plug gap should be .028" or .7mm

Hope this helps.

usually honda uses 0.024in spark plug gap, if you are using new plugs they specifically say that they do not require being gaped, if you are maintaining old plugs use 0.024in as the Honda standard.
