- This video does not show the disassembly of the engine or removal from the tractor. Its sole purpose is to show those who would like to save some money without being stuck with an inferior camshaft. Aftermarket camshafts are not something I would ever recommend putting in your engine. Its not that you couldn't get a good one, its just they dont have the level of, or any for that matter quality control. In this video I discuss the odd way the aftermarket compression release rod does not even lay flat when open. All of the cams on amazon that are off brand seem to suffer from bad reviews. After purchasing one myself, and inspecting it I could honestly say no way. However I could not buy just the compression relief, apparently its not serviceable, or more likely they just want to sell you a new cam. Anyway watch on as I use just the parts I need to get my Briggs Cam back up and running with a new compression release. NOTE* No repairs are guaranteed, and you could certainly just spend the extra 80-100 dollars to buy the cam from Briggs, with the relevant gaskets, and install that way.
I have an old JD L100 that was in pretty bad shape, including a broken compression release; I rebuilt it and got it running without repairing the cam. I found you can spin the crank by turning the screen, counter clockwise to just after the compression stroke. Then when you try and start the engine the flywheel will provide enough momentum so the starter can turn through the compression stroke and start the engine. I suspect this might shorten the life of the starter so I have disconnected the seat shut off, so if I need to stop I can slow down the engine and leave it running till I'm done using it. So far it's lasted three years doing this.
If you do not fix the broken compression release on our cam, aren't those pasts just being tossed around inside the engine case now? Not good.
@@PainterD54 Not necessarily. Steel is way denser than oil, so the parts might find a nice spot on the bottom and slide around on the bottom forever. Now if it was an engine that didn't have an oil pump, and just slung the oil around for lubrication, the smaller pieces would be tossed around with the oil, since it flies around like crazy in a horizontal shaft engine that uses a slinger to throw the oil to lubricate everything. When mine breaks I will try that, unless it rips up the engine when it fails.
No way am I going to do all that work, only to have it fail again, which it seems they all eventually do. That is a defective design. The pin is too weak where the flat spot begins. The counterweight is too heavy, which eventually breaks the pin at the weakest spot, where the cut away starts.
You can also remove the air cleaner and block off the air intake with your hand to start the engine after moving it just past the compression stroke.
Thanks for the video. Fixing my in-laws mower it just threw the compression release again and unfortunately bent the cam, took out the locating boss in the case. Watching you assemble that weight to the plastic D shape plastic etc. it looks like its a tight slip fit on the shaft . Whats the chance that weight does not walk downward when running? its somewhat hanging from the bottom side of the cam gear. It seems they intended to having that somewhat open C shaped retaining ring on there to prevent that? It didn't seem that it was enough of a flange and or if the retaining ring rotated it seems the open side could allow the weight to drop down and then who knows what damage can happen. I hate that their is that plastic bushing in there. I looked at the early cams and that weight had no plastic and nested in a machined flat so it could not walk down the CR pin. I am tempted to make a fork type plate that can retain the weight and tack weld it to the cam shaft. Alternately I see those type 31 cams being all metal and wonder if i could use one of those cams and just machine the groove in the end to drive the oil pump shaft. Cheers Ken
My 2008 16.5 does not say Intek on it but looks similar to these under the plastic. My "fix" when hard starting occured was to install a used but good 500cca Harley battery out of a touring model. I guess I should check valve actuation for the intake "bump" (and lash while in there). My plastic cover is red.
Yeah sounds like a compression release issue. Make sure the valves are adjusted correctly first. You should see that valve bump right before tdc.

Thanks! Will check it once we thaw out. Fortunately I was given a spare rider this fall with a 17.5 twin.
My 19 hp just thru the compression release. The idea disassembling the engine just really was not appealing so started looking a other options. Decided to add spark plug antifoulers to reduce compression....added 2 an engine will start and runs good of course it is down on power sume but will cut grass. Thats good enoughfor me.
Can you just buy the spring.
All lawn mower manufacturers need to be sued into ground for these automatic compression releases.
They always knew they had a problem here, and yet they keep on churning them out with no change at all.
So they can sell more new lawnmowers.
Hello Jesus....I mean,nice video dude.
Thank you my child.
WWMCD bracelets available soon.
All of which begs the question….why doesn’t Briggs sell the farkin’ decompression cam as a separate part!!!??? Why do I have to spend over $100 for a complete assembly to replace a $5 part!???
Greed.
Too much back and forth, unsure what he’s saying.
I knew where he was going, just didn't expect him to get on the merry-go-round half way through the journey ! Triggered my anxiety with the needless, repetitive babble.
B&S engine it’s a GARBAGE the best YAMAHA engine I got one many years ago and still WORKING
A Briggs engine from many years ago would likely also still be working. Problem is the excessively cheap design and I'm told, Chinese manufacture of the cheaper modern Briggs engine.
Wouldn't want to blame Mohamed or Buddha for a bad hair day.
