Right…one perfectly running mower including the shut off, finally! Many thanks again to everyone who has helped, and pointed out that a slightly loose blade in itself causes all sorts of running issues. I believe this was the cause of all my problems and the pressing plates that hold it firmly...
Thanks- a few things to look at and again understand a bit more about what that that part does now. Fuel cut off valve sounds handy as well so will look to install one of those
So...to update on this issue. I fitted the replacement pressing plates and straight away the blade held firm, and now it appears to be running like a dream! Obviously slightly annoying I pulled the trigger and bought a new one now, but we have lots of grass to mow and a spare/old mower isn't...
Yep I understand that now. Definitely know a lot more about how my mower works thanks to the advice on here. Hopefully when these new parts arrive it will sort a lot of the issues I’d been having with it.
Thanks again all for the assistance. I didn't know the slightly loose blade (which has definitely got worse over the last few weeks) would potentially cause these symptoms as well so despite the new mower arriving the other day I would still quite like to fix this one. Therefore I've looked...
It was difficult to start and the cord was pulling back. Some Googling suggested the key was worth checking and I thought it would be easy to check! It was, apart from getting the nut off.
not sure as yet what is causing the performance problems, but to be honest aside from basic checks such as...
Thanks! I suspect I have a few issues. I did manage to get it started today but the dipstick keeps getting forced loose somehow- excess pressure from somewhere? I definitely tighten it properly. It was also vibrating more than usual, then there’s the blade issue. I’ll put it in the garage and...
That is another way of doing it. But, for whatever reason my blade was spinning on the shaft (nut fully tightened), which was going to be the next thing I had a look at.
No massive issue with expensive tools. I do have a problem with expensive tools that come with instructions that make absolutely no sense and the only logical answer I get as to how to use it comes from an internet forum rather than the people who make it, or not at least to Joe Stupids like me.
I used a £5 pry tool in the end. But, you try and prep for the job and it leads you to presume you need their special tool. To be honest it was mainly holding the flywheel in place whilst loosening the nut that seemed to be the main issue and reason I bought it; I don't have an impact...
This is the outrageously expensive tool from Briggs and Stratton for this engine series. I have no idea how a metal plate and a few bolts can be just under £100:

Won't be buying another mower with a briggs...
Hi both- thanks again for your help with this problem. Managed to remove the flywheel nut using the above method, with that metal plate tool and putting a breaker bar through the square hole. Needed another pair of hands. Completely useless instructions from Briggs and Stratton and their tech...
Yes good spot- I might have sliced my finger a bit trying to undo it! Nothing too serious...
Thanks for the pointer- really appreciate it. Will give it a go tomorrow. And yes I've given it a good soak with plus gas and just added some more for good measure to leave overnight.
Hi all,
I am attempting a repair on my Makita lawnmower which has a B+S 675Exi engine. I believe that the flywheel key is the culprit for difficult starting/rough running and therefore have taken it apart to access it.
I have bought the special (and very expensive) tool that supposedly both...
