We check out a John Deere Z335E zero turn mower with a Briggs and Stratton V twin 20HP engine that bogs down under a load and has no power.
Once we pull it onto the table we start getting popping coming from the left side and do a dull diagnosis and repair on the pushrod/valve issue that it has.
We go through some of the common troubleshooting and diagnostic methods to take you through an easy repair

Thank You for your service and time making all the videos and sharing your experiences with Us I feel sorry for the families who are suffering due too prices I have given away a lot of used parts when I’ve gotten my money back allready It’s not being weak but it’s a other way to help the kids eat better

[@IndRepair]

Glad to try and help others get their stuff fixed! We always help when a situation arises where we can be of assistance also. Used parts is a good way to do that without coming out of pocket yourself. Very nice of you!

Where did u get the spark tester? Enjoy your videos!

[@IndRepair]

Thanks! We get ours through a distributor but you can find the tester at www.ebay.com/itm/155608498870 I am in no way affiliated with this listing

[@philliphall5198]

I usually pull cover and blow it out And on push mower I look at blade I like the spark tester but I’m to old to be buying a lot of stuff at 72

[@IndRepair]

Haha I hear that one! Best purchase ever in my opinion! I have 6 or 7 just because they stopped making them for a while and I was down to one them couldn't find them!

[@philliphall5198]

@@IndRepairI really want one but my wife meds are 373 a month with good insurance from company retirement She’s still first 😊😊😊

[@IndRepair]

I understand that much! She's lucky to have you looking out for her!

[@phillipduncan2497]

I wonder what the condition is of the other cylinder head?

[@IndRepair]

It was just barely out of spec but we adjusted it also just for good measure. Both studs we secure not loose like this side

[@andybecker2693]

How many hours were on the unit? My guess is 200-300 knowing Briggs but somebody has been in there already.

[@IndRepair]

Had 357 hours on it. Who knows what they did before! Didn't even bother to seal it back up or worry about leaking. Based on the lack of oil leaking in the area I think someone was just into it

[@jr6281]

I’ve got the same unit. 46 hours on it, and it starts bogging/losing power after about 15-20 minutes. Fuel supply issue like you said at the beginning of this video?

[@IndRepair]

Definitely where I would start, pretty easy to diagnose if you put a clear fuel filter in line between the pump and carburetor to see if it is running out of fuel

[@philliphall5198]

109 today and 107 now AC house blowed silver can electrical Replace it ok To hot to keep working in shop 115 at 11am this morning

[@IndRepair]

Yeah it wasn't nearly that bad here because we have been in a drought for over a month no humidity but we would have definitely went home! Finally starting to get back to where we don't have to put in 14 hours a day to stay caught up so we are not complaining but would love just a little bit of rain!! You can keep the heat!

[@iki911]

I can't stop thinking, why you didn't take the cover off

[@IndRepair]

There would have been a little more room but I am used to working in areas like this. Thanks for watching!

[@tier1solutions28]

Z915e. 25hp kohler. Runs perfect at idle but when you push the arms forward it loses power. Any ideas?

[@IndRepair]

Check each cylinder independently to make sure each is firing. Blown head gasket, carburetor gummed up, one cylinder not firing, bad fuel, etc. The list really goes on but you have to start somewhere and eliminate each one by one. If each cylinder is firing, the fuel is fresh and it does not run better with the choke applied slightly I would want to do a leakdown or compression test to find where the issue is. If it runs better with a little choke check carburetor, fuel supply and possible air leak

[@tier1solutions28]

@@IndRepair great advice. Thank you so much

[@tier1solutions28]

@IndRepair is it okay to run it long term with the choke opened slightly?

[@IndRepair]

Glad to help thanks for watching

[@IndRepair]

Running with the choke on partially is ok short term for testing but not something you would want to do long term

[@mikeevery2459]

Head gasket issue

[@IndRepair]

Not on this one

[@MrJohnnyb42]

Gaps are usually 7 do you agree?

[@IndRepair]

Valve spacing you are speaking of correct? If so, the repair manual show .005" and separate spec charts say .004" to .006"

[@JamesScar-eo1ch]

Didn't hear that when he drove it in? Yeah right.

[@IndRepair]

Wasn't popping symptoms sometimes change but thanks for watching!

[@JamesScar-eo1ch]

@@IndRepair yr right, my bad you did say it was making noise on that side, and it's hard to hear it when yr in the seat. So I apologize for being presumptuous.

[@IndRepair]

I understand completely appreciate it

[@mtnpwr]

Why didn’t you just remove the rear panel to give yourself better access to the cylinder head/rocker arms? Seems harder to work around it than just simply removing the panel.

[@IndRepair]

It wasn't in the way for me when I did this. I work in tight spaces like these and much tighter daily. If it helps you to see what it going on or makes it easier for you by all means take off the panel and get better access. Thanks for watching!
