Briggs and Stratton OHV - Stripped Spark Plug

[crashz]

This past fall I tried to start my pressure washer and was having a hard time. Its a Troy Built 3100 psi unit that I bought from Lowes. Its been kinda finicky since the first tank of gas ran through it. So I went to pull the spark plug and it broke clean at the threads. Any tips on how to remove the threaded "insert" left in the head? I'd chuck this box store POS, but it wasn't cheap and has been used very little.

Will it thread on down? Take the head off remove from back side. Guess all it will cost you is a gasket and time????

You need to pull the head because the ceramic tip probably went inside or will and will destroy your engine when you start it. Unless you got lucky and it's all attached to the part that broke off. Then use a bolt extractor down the center of the threaded bore of the plug. I would watch trying to screw it in. If there is a lip on the threads still left, you can destroy the threads in the AL head.

First thing I would is pull head and scope out what needs to be done....

I Personally have given up on B & S engines . When ever I have any issue's with them , they are chucked and replaced with the Predator from Harbor Freight . Replaced the engine on my log splitter several years ago and have had no issue's since . Starts a lot easier also . Also about to give up on the Honda on my pressure washer . Replaced a 3.5 h.p. vertical shaft on a old lawn mower with the 5.5 h.p. predator . Thing is a mowing beast . Only use it a few weeks every spring and it starts every time .

We are doing the same for my Dad's old log splitter and a gas air compressor my brother is going to sell . Just my opinion .

Does the OHV motor come apart like the old ones? I was worried that I would screw up the valves.

Crazy, but the ceramic tip came out clean (and the it was in decent shape). So its just the threaded section that's stuck.

I was thinking of doing this as well. I literally have about 15 hrs of run time on this pressure washer. And for 14 of those hours, that B&S has run like crap.

To pull the head, I have to remove the engine. So I'll pull it apart and if I screw it up, a Predator engine will go back on!

Real lucky. Go buy a lottery ticket. On the way back get a set of bolt extractors from the tool store. I prefer the square ones, they bit better from my experience. I used to buy them at Sears, but not sure where or what they sell anymore. Last set I bought online. The one below is similar, not sure what brand I bought. If you use them enough, the smaller ones will break on the tough jobs.

I would just use the correct sized ez-out and remove whats left of your plug.
