I always, if possible, install a fuel shutoff valve.
I always shutoff the fuel and run the carburetor dry and finally turn off the key. I’ve had too many, over the past 30 years, carburetor needle and seats fail and dump the fuel into the oil.
Once you have fuel in the oil bad things happen...
You are correct! Unfortunately, it’s not an original Briggs carb. My experience with aftermarket on this engine has been hit and miss. Mostly Miss! The main jets tend to be too large.
I believe the original poster is ordering a new aftermarket carb and hopefully it solves the surge
I looked closer at your carburetor and I believe it’s aftermarket not original. Original Briggs carburetors have stampings. Usually Walbro. Your carburetor is way too clean for the age of the engine!
If you still aren’t happy, then I suggest you consider this new aftermarket and call it a...
Great job! Do it again 3X
How about the bowl nut/main jet?
The surging is usually from the small jets on either side of the choke butterfly.
What choke/carb cleaner are you using?
Any compressed air?
Might need a new gasket?
You are lucky it has the teeth on the flywheel! You can add electric...
That’s it. Born March 2, 2002.
Did you check for any teeth on the flywheel?
If needed I can post photos of the carburetor and where to spray cleaner?
Which carburetor do you have?
I’m reading wisdom above!
This is a great engine. If you check the flywheel it might have teeth for an electric starter! I made an outboard engine out of one.
I do. Here is my recommendation.
This engine is now probably close to 30 years old. I have 6 of these on hand and have worked on many over the years. It’s a great engine if you change the oil with 30W or 10w-30 annually and keep a clean air filter on it.
Can you post a photo of the...
It’s kind of odd.
My experience is Briggs you screw in to check the oil.
Honda is you do not typically screw the dipstick in. This allows a bit more oil to read full.
Kohler is you do not typically screw the dipstick in. Again, it allows a bit more oil to read full.
I think 48 oz is a good...
I’ve never had an issue with 30W and I prefer Penzoil 30W.
If it’s under warranty, then 10w-30, if the warranty calls for it.
I have a few Kohler engines on John Deere mowers. Manual calls for 10W-30. I use Casteroil 10w-30 and I’ve noticed a slight bit more oil consumption with the 10w-30...
