Unhappy Carb Help Needed

The engine on my Craftsman blower would sputter once in awhile only when idling. Otherwise seemed to run fine. Since it's simple to do, I took carb bowl off & found a bunch of small particles in the small amount of gas still in there.

So, should I remove carb, take in all apart & clean it. If so, can someone tell me how? I just successfully did this to my Honda generator following step by step instructions. So, I feel confident that I can do it.

Blower info is down below. But I'm unsure of the make of the engine & the type of carb. Found the emissions label which had "MTD" on it. And I watched some YouTube videos but my carb doesn't seem to be a fixed jet or an adjustable.

Please help.

Chuck, You need to get the numbers off the engine. There should be a sticker somewhere on it. I think the 357 is a Briggs motor. It may still say MTD and have long code type numbers, but there should be something like a (model, family, type, code, serial), blocks on the sticker. Those are the numbers you want. Post up those numbers and we can easily find a schematic of your carb.
I'm thinking it's a Powermore now that I look around a little more. They are kind of a PIA to work on as they have a bunch of shrouding to remove to even get at the carb. I'd try cleaning it, but at this replacement cost, you may want to buy new.
Could be an LCT or Powermore also.

I found this,
357 cc Horizontal Shaft 483-SU, 483-SUA, 483-SUB
So I am guessing an MTD engine?

MTD Engine Parts | Model 483-SUA | SearsPartsDirect

For the number you listed.
It came off this site,
Craftsman Branded Engine Parts MTD Powermore Parts - MovingSnow.com

Someone should be able to tell you exactly what you have, the above is just what I found while searching your number.

Are they little black particles you found in the carb? Is there an inline filter on it? Can you see into the gas tank?

Thanks Big Ed.

The carb looks like the one in your link. Model # 483SUA.

There are some black & some shiny gold particles. No in-filter but I'll be adding one. I'd consider adding a shut off value also but it'd be located under tank & I'd have no access to it. I have the tank off right now but can see inside only a small amount.

It shouldn't be that dirty for it's age.

I would slosh some ethanol around and clean it out, but I get mine ethanol for free.
You could use some rubbing alcohol, Isopropanol to rinse it out as long as it is off. 99% if you can find it otherwise use the 91%. Other percentages are denatured with solvents, I would use either 99 or 91 %'s.
I get my Isopropanol for free too. (I get all my chemicals for free.)

Sometimes the black may come from a new plastic gas can?
The gold from the new tank itself?
Or maybe a fuel line is deteriorating? Or a primer bulb if there is one.
Do you add to the gas?

My little Craftsman was stuttering a little too, I added a carb cleaner to the gas and it smoothed it out.
I really should take mine apart as I have never had it apart and the blower is around 14 years old now. but I figure that it is running good why mess with it.

A lot here recommend using Sea Foam additive to the gas. I use Stabil and a shot of the carb cleaner to each tank. Some say that the Stabil marine grade is better to use.

Someone more experienced then I am should chime in with some suggestions.

Why would I not want to use gas? I didn't know ethanol could be bought. I do have that rubbing alcohol. Must be nice being able to get stuff for free.

I have been using Stabil for years. And recently started using an additive for the ethanol.

What do mean that you use an additive for the ethanol?
Are you calling the gas you use ethanol?

The ethanol I am talking about is either 190 or 200 proof grain, for drinking.
You can buy ethanol, but it is denatured mainly with a percentage of either methanol or isopropanol. That is so you can't drink it. The ethanol with the isopropanol is better to use in my opinion. Ethanol when denatured is labeled as denatured alcohol. But you have to watch as there are a lot of different blends of denatured alcohol. Some are denatured with chemicals that will eat through rubber and plastics. Any ketone will harm plastics and most rubber, they are more of a paint stripper solvent, Methyl Iso butyl ketone or methyl ethyl ketone,etc. And a lot are also denatured with acetates, a lot of acetates will eat through the rubber and plastics too. Butyl acetate, ethyl acetate, etc.
But denatured with just methanol or IPA (isopropanol) won't harm anything unless someone drinks it.

The ethanol will cut the varnish residue that might be built up in the tank.
The ethanol will clean it out better then gasoline and it dissipates (drys) quickly.
But like I said I get mine for free.
Straight grain is great for taking off sticker glue, if you ever tried to remove a old bumper stickers glue you know how hard it is to come off. Rub a little ethanol on it and it comes right off.

I was just thinking that you can use the isopropanol to rinse out the tank as long as it is off.
I guess you could also use some fresh gas if you want.

My main point was to get it clean as long as it is off.
Whatever you use get a coffee filter when you pour it out after you rinse it.
See what if anything gets caught in the filter.
