In this video I fixed the trash picked tiller with the briggs and stratton engine from hunting / surging. What that means is the idle is not constant and steady. The engine revs up and down. This was an easy fix that any one can accomplish.

Perfect demo. Keep up the great work!
Exactly what I was looking for to get my trucut reel mower running properly again. Thanks man!
Thanks for all the tips on fixing that carburetor. Great learning for me. Thank you. Thanks for the video's
Nice video, it helped me. I figured i had to do a carb rebuild. Its been sitting for awhile. And you and i have the same tiller which helps a lot. Thank you.
Thanks for the great video! I have the exact engine and it’s running the same way.
easy to understand, and good camera work, nice pics of linkage
Nice video on a hunting 5 hp engine. I've similar engine hard to start gonna give this a try.
Tight work Big Hoss !!
fantastic man, thank you, subbed
This is crazy! I bought this exact model Tiller yesterday for 40.00 has been sitting in garage for thirty years! Looks brand new! Wont stay running....
Thank you for the information
Great video.
Thanks for the video. For about $10 and less than am hour of work, I was able to clean and rebuild the carb on my chipper/shredder that has the exact same Briggs & Stratton engine. Runs like new now.
Where did you buy rebuild kit?

Good fix it video. ✌
Good how too video .
Thats the type tiller I just got. Now it has this choke/ surge problem
Thanks for the video. I noticed the large filter that covers the part of the carburetor that sits in the tank bowl is missing. I'm guessing it wasn't there to begin with?
I have same engine. I rebuilt and cleaned carb. It runs now but only on choke. Didn't run at all when I got it.
Having worked on a bunch of these over my 67 years, sometimes you can just buy a new carb for very little more than the gasket kits and the new one comes with gaskets.
I bought an old tiller with this motor on it that was surging and running badly. I just put a new ebay carburetor on it and it runs better,but still surges. Could the governor need adjustment, or do you know what else I could do? I used new gaskets and fresh 89 octane fuel.
who the fuck care about buying new stuff when the point is to fucking repair the problem ? ... damn boomers
@@ciphercode2298 Did you get it to run any better yet ? mine is doing the same thing.
robertson mine has what they called a pulse jet( I think) carburetor on it. It bolts directly to the steel tank and draws fuel up its tube and puts it into a bowl built into the tank and then it can draw it into the motor. On mine the bowl was rusted out. I tried cleaning it up and using jb weld, but it's full of pin holes and the fuel drains back into the bottom of the tank. I couldnt find a suitable replacement tank. I ending up getting a 6.5hp predator engine from harbor freight. I had to Biden out my mounting holes and redo the way the tension pulley mounts. The surging is a sure sign of a lean running condition or faulty governor. I did check my governor and it was adjusted properly.
@@ciphercode2298 Thank you very much i will check it out tomorrow.
aah, that is the style air cleaner n throttle I need as I got a new carb for my tiller it was different than yours,, carb I ended up with is just like that so need that throttle/choke setup and the air cleaner, as I could not find any cleaners with that spacing...
Just checked head on motor and did not have dual spacing so could not use that carb.. I already robbed the fuel pickup filter for another tiller and wondering if I could just put some hose and drop a stone style filter like on a weed eater into tank instead.. then have a better filter I could change.. anyone try that?
I’m not sure, if this helps. I been using my fathers tiller since he got it 10+ years ago for our garden. I think it’s normal the engine idles rough like that. The engine needs that little extra when it start feeling resistance. My problem this year for our garden was that the tiller idles softer and no longer *hunts* for gas. She does dig in the ground but the amount of man force it’s required to dig a little deeper and/or climb out the hole is a lot more wear on the body. I’m need that engine hunting, it’s what tillers do. Idk nothing though.
I cleaned out the original carburetor kept hunting still I even bought a new carburetor and the dang thing is still hunting. I don’t know what else to do. Ten hp B$S flat
Good
I did everything that you did and mine is still surging. Do you have any idea why it is still surging?
What about the low speed idle screw on the other side? Very important during a cleaning. Looks like it was overlooked.
on my engine the screw will just suck itself back in if it is unscrewed, even on a brand new carb.
I got the same engine on a generator that wouldn't start because of fuel issue. Got a new carb for 13 bucks, replaced it, but the engine is surging the throttle. Governor is pulling it back constantly, under idle and load not sure how to proceed with the governor.
same with mine
@@ethan5.4s89 I figured out the issue. The fuel tank has a fuel bowl integrated into it, mine had a slight rust hole so you need to figure out a way to patch that hole so it can get a constant supply of fuel without draining
I just did everything you did in this video and the surging is gone. However, it's still a pain in the ass to get started. I didn't replace that diaphragm gasket and it looked "trampolined" like yours and is "stiff-ish". Could this gasket cause a really hard starting? The tiller works fine if I quickly throttle it up after starting AND open the choke all the way, otherwise it will die. It will not idle after start... it will run for about 5-7 seconds then die off. I can't figure it out. Any advice would be great, thanks.
Replace that gasket along with the spring and spring cap like this video here - czcams.com/video/WhpYKlufwko/video.html
@@Fentertainment Thanks, will do.
The diaphragm is a fuel pump. It moves fuel from the tank to the little cup directly under the short pickup tube. Without fuel in that cup, they are a bear to start.
@@mrunit7261 I figured this out after messing with this thing for a week. Practically rebuilt the thing trying to figure it out. It was the bowl... bone dry =]
I have the same engine that is running pretty bad even with a new carburetor on it ,are there any adjustments that i can make to help it run better ?
me too, did you ever fix yours?
@@josewales892 Sure did Bill , i wasn't able to fill my fuel tank all the way because my gas cap was leaking pretty bad so i ordered me a new gas cap and filled my tank up all the way and it run like a new one after that.
@@jackierobertson1528 i’ll have to take a look at that, i put on a new fuel line and it keeps getting air in it, i used a clear line so i could see but i pull line and bleed till it’s all fuel then pop it back on and start and within a few minutes it has air bubbles in the line again
Put a brand new carb on mine,but it's still surging. What else could I do or check? I'd love to get my tiller running.
might have to adjust the air/fuel mixture screw
@@Fentertainment I'll fiddle with it some tomorrow, but I've got a feeling it's not gonna fix it. Seems strange that both carbs run basically the same. There was some rust in the tank and the guy I bought it from said he rebuilt the carburetor. When I removed it he'd taken the screen off the bottom of the pump and it'd sucked up all kinds of debris. I cleaned the tank out with vinegar while I was waiting on my new carburetor to arrive.
@@ciphercode2298 Those old briggs tanks are notorious to rusting and if the carburetor did get any rust in the carburetor then it could obstruct fuel. I have a tank here that my neighbor tried to use vinegar in but the tank was too far gone before he did that. I looked for a used tank on ebay but he didnt want to pay those prices.
@@Fentertainment mine wasnt real bad. Probably woulda been ok if he hadn't taken the screen off the bottom of the pickup tube. Looked like they'd left the tiller just sitting out in the open all the time. I'll get it figured out,its just frustrating not knowing which direction to take. I dont mind fixin stuff,as long as I can diagnose the problems.
@@ciphercode2298 If you have the tank off then just get all the rust out that you can and then use a tank sealer like Red Coat. It will seal any rust spots and bind them so no more particles come off and clog any of the ports.
Better have a gasket set in hand before picking up a tool. Guarantee anything of that vintage is not going to come apart without trashing gaskets. Strong dislike of those pulsejet carbs.
