jb weld works great for the cam lobe repair.. hahhahah not out of norm for that to ware. but not something you see every day

[@901ronnie]

Wow. Like you the cam was the last thing I would have thought of. Blower looked like it was well cared for. Was expecting the plastic cam shaft and surprised it was metal. Maybe the lobe wasn’t hardened enough? Steel on steel you would think the cam would outlast the rest of the blower. Good video!

[@waynestefinashen239]

9 years in business at Eliminator Performance and yes we have had valve issues but never this much wear on a lobe of the camshaft. Amazing it would wear that much. Thanks for this one Bob.

[@rogermcdonald1607]

Very good diagnosis process Bob. New cam and you should be good to go. I think low zinc in these engine oils causes alot of these problems! 👍🎥🇺🇸

[@doublewide6]

Thanks Roger

[@crisprtalk6963]

Great observation on that exhaust rocker. Well done!

[@TheCrittercam001]

Great detective work DW

[@beanolatte2682]

Good diagnostic video. Weird the exhaust lobe wore that bad.

[@Big_Johns]

Good video and troubleshooting Bob. Strange it ate that much of it, luckily you were able to find a replacement. 👍

[@watermanone7567]

NIce video: I have several Briggs engines in my shop with bad cams this last year. Mostly, however, it has been the compression release failure that failed. Back ordered from Briggs for 6 months or so. I ordered aftermarket cams and fortunately have not had any issues knock on wood. Thanks for excellent video's.

[@JShep-yu3ki]

I've had 2 aftermarket cams fail on me in the last 8 months. They both failed within a half dozen starts. One had both cam lobes spin on the shaft and the second had the cam gear spin on the shaft. They're pressed on the shaft and it obviously didn't have enough interference fit to keep them in place. I guess you get what you pay for in the aftermarket.

[@watermanone7567]

@@JShep-yu3ki Thanks for the input. Hope I don't see the failures in the ones I did. To bad you can't get quality parts in some cases. Thanks

[@rverro8478]

@@JShep-yu3ki It makes me wonder, can you do some tack welds to keep the lobe secured to the cam ? Unless it's them $%&* "plastic" cams.

[@JShep-yu3ki]

@@rverro8478 it wasn't a plastic cam but once the cam gear spun, I would have been guessing where to put the timing mark with respect to the lobes so I got the timing right. I just threw it away and got my money back from the seller.

[@rverro8478]

@@JShep-yu3ki Good. I was wondering though, IF making some tack welds before installing it, would've helped. I know you're not supposed to but, it was just a thought.

[@harveystephens6115]

Good training v. Enjoyed

[@Maximus43968]

That was a crazy one for sure. With that much wear l am going to guess the other shop adjusted the valves when they had it in for the new carb? Very good catch sir had my mind working as you was going.

[@baddad5781]

I'm learning alot from you buddy. Ive seen this issue a couple times before. I assume this issue is pretty unique yes? Thanks for going through this problem and sharing with us.

[@davecarlson9350]

Unfortunately, Briggs & Stratton has let the bean counters take over. Now they're pretty much Breaks & Scrap'em.

[@adnacraigo6590]

Good diagnostic work.

[@DIYVariety]

Great job bob

[@donmayberryjrsOPE]

Hey 2-Wide great video! Those damn spark plug hole positions, they do it on purpose! Use a "tube-like" socket, as I'm in the ones Honda included in their tool kit, work great.

[@berardia4]

Good video.. Before you tore the engine apart I was thinking check the pushrod. Possibly it was too short. But probably lack of oil or bad casting (but I question that if the other lobe is good.)

[@elgkas9928]

Someone had to be in that head adjusting the rocker arm previously to take up the wear on the cam. If not, the excessive clearance between the tappet and the cam lobe would have caused a no start condition from the exhaust valve not opening.

[@dtom1145]

Good diagnosis. When I change me mower or snow blower oil every season I run it through a paint filter to look for any metallic particles. Been using full synthetic for about 30 years and have never seen a problem.

[@rverro8478]

Good to know. Thanks for sharing this information.

[@kpdvw]

nothing but the finest quality....!

[@lawrencecarroll2031]

Good diagnostic video! Would you have any idea why the cam lobe wore down the way it did? thanks

[@Turningwrenches85]

Good work there bob , shame though the lobe wore down on that camshaft wonder if a lack of oil changes caused this since it had metal in there prob loss of viscosity.

[@larryfine4498]

I couldn't justify the time spent on this machine. The resale value on used equipment in my area has bottomed out. Especially snow throwers. Surprises me given the cost of new machines. Good video, good diagnosis.

[@Shawnee.Hills.Small.Engine]

Good video Bob. Briggs and Stratton definitely has issues with their camshafts.

[@waynestefinashen239]

You got that right Shawnee but normally broken compression releases.

[@ryan_80]

Hey. Great video and have same popping noise with my MTD 10hp Tecumseh engine. Wondering how you made out after replacing cam?? Thanks and much appreciated!

[@MikeJones-jr5hb]

Good diagnostics! Weird though

[@johnlow3894]

wow! that was ground down so much. made for a great video though!!

[@Xzavieur]

as for the sparkplug, I've personally had great luck with wobble extensions for getting at those weird angles.

[@kenhilson786]

I bought a used 1350 which I believe is about 9 hp as a repower. It starts fine with pull cord when cold but after running just a few minutes it will only start with electric starter. If it sits a bit it will again start with pull cord. It runs and blows fine. I tried carb and coil swaps. No change. Checked flywheel key. Adjusted valves. Did leakdown and compression. I also suspected too much compression release. I even put a degree wheel on it and compared results with an 850 model. IIRC I even checked lift with a dial gauge. I gave up , not wanting to open it up. Maybe it's the cam in an earlier stage of failure than the one in this video

[@sixtyfiveford]

Now That's a flattened lobe. Dang

[@nashguy207]

That cam was shot. Really surprised to see that wonder if it is a common problem on those engines.

[@KSMike1]

I was thinking it was the engine too. 😂😂

[@vernonbruce3722]

what would cause that cam to wear like that?

[@tomycodd]

Thank you so much for this video! I have not come across this particular problem- The amount of wear on that cam lobe is incredible! Does the valve tappet show excessive wear as well? What caused the lobe to wear like that?

[@TecumsehRulesbcserk]

These Briggs engines are pretty notorious for their cylinder head issues, especially on the exhaust side valve.

[@patrickmiller3621]

Nikki carb, it more than likely was run with gas in the crankshaft in its past. probably why they changed the carb. very common with those carbs for the float to stick and fill the crank with gas. I always shut off the gas after using it solely because of these.

[@t-bear1863]

That tappet has to have some wear as well. Good find though.

[@johnsmith-sw7ii]

Push rods OK????

[@mikespain8655]

Unbelievable amount of wear on cam exhaust lobe, and intake lobe looks good. Very strange. Must be an inferior part that wore poorly.

[@donmayberryjrsOPE]

Mike I've got 2 Generac 7500 watt generators in my shop doing the same thing and with the same exact issue.

[@mc2whls]

Even the metal camshafts are BAD. Briggs & Stratton DOESN'T care about their reputation anymore.

[@stevesmith6058]

Hey man you never run a spark plug in with an impact gun you had the right idea use a fuel line and screw it in or you gotta strip those dreads out real easy

[@demetriosa7646]

Throw in a nice reliable Tecumseh!

[@briankelley6185]

Noticed the exhaust valve bump twice

[@donmayberryjrsOPE]

Crap for quality, not changing the oil every 10 hours, running on low oil for extended periods, BLA, BLA, BLA

[@user-ls1mx5ks2w]

I really didn't hear much. Most likely the air fuel mixer is off due to old stale gas
