Hi! To answer the question about the ”traffic light”. The breathers function is to maintain crankcase vacuum. The yellow is a one way fibre disc, limiting the air flow direction caused by the piston going back and forth. It allows air to flow out of the crankcase but blocks the return flow, maintaining a vacuum in the crankcase. The partial vacuum must be maintained in the crankcase to prevent oil from beeing forced out of the engine at the piston rings, oil seals, breather plunger. There is a way to test the condition of the yellow disc. Let me know if there is a interest and I will write the instruction. Cheers from a briggs mech in Sweden.
Mower man I really enjoy your channel. I especially like when you teach your children how to work on the mowers. Thank you for taking time to share these videos. Your friend from across the pond.
can i just say that i have learned more watching this video than most of the other videos i have seen on this! the time is 1am after an 9hour shift at work and i was so hooked that i couldnt stop watching , this video is now saved for future reference and just wanted to say a big thank you for doing this and looking forward to watching more videos of yours
Watched the entire film & it was brilliant from start to finish. So informative & well explained & presented. Well done Mower man & thank you very much. Watch out for Kevin!
I have a broken down 450 series that I don't want part with. So I have new oil, spark plug, governor springs, diaphragm, air filter, flywheel key, primer bulb and throttle cable ( yes, it's had its bad days, LOL!) alll on their way. I have never changed the oil in the 8 years that's I've had it, though I may have topped it up once? After watching this video, I'm keen to see how she runs once it's all put back together!! Appreciate the video, it really helps!
@@MowerMan ***Update 20/10/2020***I put the ol' briggs back together yesterday with all the great help from your videos. This morning added some fresh fuel, primed her up and she purrs like a kitten!! Good as new ,starts on the first yank and should last me ages longer. Many thanks for your videos!
Hi really good video lots of good information, well done to David for starting the job for you he did really well, you got a great assistant. Keep it up.
Hi Mower Man, you do a very thorough job, very professional and I was able to follow you with full comprehension from beginning to end. Learnt a lot and enjoyed your instruction. Regards Pete. Australia. Ps am subscribed.
Hi, l am currently servicing the car by on my Victa 160cc 2-stroke. Waiting on full kit to arrive by post. Bought her new 11 years ago. Great mower for steep country and long grass being a utility ( side thrower). I also run 4-stoke Briggs. Lots of mowers get shot out here at the by annual council clean ups so I am going to start a small business on the side. Thanks a lot for your great body of knowledge. Regards Pete.
I need help. I got lawn mower out of trash and it fired up, I fixed the key and cleaned it. It starts but it gets really hot after 20seconds of running and the noise is a little bit weird. There might be a little too much oil. Not sure what to do. Any help apreciated.
Hello. A great video and has shown me a lot of info and given me the ability to fix the mower myself. I have 1 issue though I cannot find the link for the governor springs on the internet, where can I get one of them from? Do you have a part number please. I have lost mine.
This is a great video - thanks for filming! I've got one of these engines and it struggled to start after running for a while. And now it doesn't start at all. I noticed the cooling fins on the block were filthy so is potentially overheating. Took the spark out and can feel no compression whatsoever. I have another engine identical which I know runs and has compression . What do you think is the better idea - swap the whole engine out, or strip down the one that's not working, replacing gaskets etc? Cheers!
thank you very much your help has been invaluable, much appreciated and 1hr 27 min look with your eyes lol normally the children look with there mouth first
It's a flat head engine so you cant set the valves without grinding. Governor flap takes care of itself. Set the ignition coil gap and make sure the springs are correct
Sometimes the cheeky greedy lawnmower shops here in new zealand weld the blade boss and blade on to the motor they even weld around the blade bolt so u cant replace repair change or sharpen blades iv had afew mowers like that
Take the brake crap off just get a throttle control i take them all off im in new zealand so we just have it like our popular masport brand mowers and our lawnmaster mowers

Garden hire spares. Ask them for briggs classic governor springs
A very thorough video!
Yeah It was a lockdown special for sure!
Good video...great work David 👍
Glad you enjoyed it

Great video, I wish you were based here in the North East. Regards, Rob, Maxwells grass cutting services.
Rob W. Thanks Rob !

Glad it helped!
Very informative ☺
Ronald Maxwell Thanks Ronald
How do you set the timing on these and governor arm.
It's a flat head engine so you cant set the valves without grinding. Governor flap takes care of itself. Set the ignition coil gap and make sure the springs are correct
I can’t open your website ??
Great vids i love it when your kids take a like in what you do takes me bk to my son helping me with cars
Cheers Gary !
The blade was obviously not centred when you were trying to get it off as you’d already partly undone the engine from the mower body.
Got a mountfield with rotten deck, anybody got them please?
Sometimes the cheeky greedy lawnmower shops here in new zealand weld the blade boss and blade on to the motor they even weld around the blade bolt so u cant replace repair change or sharpen blades iv had afew mowers like that
The fin cover just collects dust and dirt i take them off the mowers i repair
Take the brake crap off just get a throttle control i take them all off im in new zealand so we just have it like our popular masport brand mowers and our lawnmaster mowers
Take the fin cover off and bin it
