The Spark plug seamed to gas foul, this can’t be possible while the engine is running is it?

Seams like w/ engine warm the gas would just burn.



Anyway the new engine had a none briggs spark plug, oddely enough it was putting out a little spark not sure how stronge it was.

Swapped in old engines briggs spark plug and now how ignition, waiting for grass to dry then try her out round 2.



I see 2 types of plugs briggs & champion which is the preferred spark plug for, couple years ago I gave the local snapper dealer $6. for the correct plug so I have the # if the briggs is the preferred.https://www.google.com/search?q=intex+12.5hp+spark+plug&oq=intex+12.5hp+spark+plug&aqs=chrome..69i57j33i10i160l3.33746j0j15&sourceid=chrome&ie=UTF-8

btw my 04 Johnson175hp outboard engine only likes champion it'll run on a ngk but not optimally.

Intex 12.5hp.



Additionally just observed the SP cap is a press on the twist to keep off muffler (there is a screen loose at the mufflers outlet is this normal the old isn’t like this.
edit: what the oil capcity I poured just under a quart? I only had 5w30 should I drain and use plain sae30weight

Thanks
Are you talking about a screen spark arrester on the muffler outlet?

What is an SP cap?

OIl capacity is around 1-1.5 quarts. Check your ENGINE manual to be sure. Make sure you keep it on the FULL mark. Not over nor under. Check it and ALL mowers prior to mowing. Simple check while you slug in some fuel.

Never use 5w-30 in these engines. Briggs says you can BUT you will burn it away pretty fast. Especially in hot 100 degree temps, not recommended. Use 30w and never look back. You can get a gallon of 30w at wallymart for cheap.

If you are mowing wet grass, you need to scrape the deck out after mowing.

Slather on your used engine oil under the deck too. Keep it from rusting out especially over the winter.

yes I always use a paper inline filter also petcock and always run the carbs bowl dry.

dam didn't know about the deck rusting from underneth dam she doe's live in a shed however the deck is exposed to moisture in the air due to the door doesn't completely airtight , it's a shed I slapped together what to see a image.

I would install a paper fuel filter and a fuel shut off valve inline to the carb. I do this on every mower I have.

Best plug is a non resistor that fits your engine. I prefer NGK in everything but Champion is just fine in a mower.

Keep the tires at 14psi in the front and 10 rear. Grease the front wheels and if yours has one the bearing on one side in the rear. Valve adjustments yearly to promote easy starting. Clean the cylinder cooling fins YEARLY or more of you are bagging. Grease the spindle kind of hidden under the blade yearly. Keep the chain case and rear diff full of 00 grade grease. Tractor Supply has a quart of 00 great for around 5 bucks.

Keep the deck scraped clean and don't mow wet grass. At the end of the season, last mow, slather your used oil under the deck with a paint brush. Will keep it from rusting over the winter.
