Ok, so i followed the tutorial on how to clean the carburetor on the technical section and i have some ugly news...

Now, the big chunks were already in the container, but as you can see the gas that came out from the hole were the petcock sits it's pretty ugly... there's rust in the tank, and this is just the beginning...
The gas on the left instead it's the one that i drained from the petcock emptying the tank as the tutorial says.

this is the lower bowl of the carb...

I just hope to have not compromised the engine... i guess i have to change the tank :'(

Here's the carb in the process of disassembly and cleaning...

some other pics of the carb

As SavageWahine noted in the tutorial (step 16a), this is i guess the kind of carb that is featured in the clymers manual (that i don't have, instead i have downloaded the Suzuki service manual).
Well, i hope tomorrow that some stuck bolts will come loose thanks to WD40, i will get some brake cleaner and the seafoam (here where i live there are a bunch of hardware stores for yachts and marine applications so i'm confident to find it or something similar.
Again and again, thank's to you all guys.

You don't need a new tank. Just clean it. Dump all the fuel, put the petcock back on. Add 1 gallon of vinegar and top off with water. Let sit a couple days and see if the rust has been taken off the tank walls/base. If not, buy some oxalic acid (wood bleach) and follow the directions for 8.3L of solution. Keep checking the tank, when you see black spots instead of orange spots, it's good.

No need to line the tank unless it perforates while pickling the rust.

Read THIS thread in its entirety, tribulations and pitfalls of cleaning gas tanks with vinegar. Hey, it's cheap and normally works...http://www.dotheton.com/forum/index.php?topic=32531.0

It sounds like it is running too rich. What jets are in the carb?

Hi Dave so i took the carb apart and with a little bit of frustration i have to say that the only jet of which i can read the size it's the pilot jet, and it reads 47.5, not to mention the two bolts that keeps the throttle are jammed...
the main jet it's in a very bad shape and i can't read the size and for the needle jet, where in the tutorial says where it has to be, there's nothing, as a matter looks like this is a different version:

I've disassembled the diaphram and the needle reads
5C16
Hope these few data can suggest you something...

Reply #18 - 04/02/13 at 13:26:49 just now i found this page of the forum, where lists the specs of the carb... http://suzukisavage.com/cgi-bin/YaBB.pl?num=1098869040/7 seems mine it's fairly stock, at least the few parts that i have been able to "decode"...

Well you found the cause of it running poorly......junk in the carb!

If you want to tinker with the jets.....you got some more reading to do.

For me....I had great success with a 50 pilot and 150 main, with 2 washers on the needle in place of the white spacer. I had a stock air cleaner and Dyna muffler. Most people try a 52.5 pilor and 3 washers, but this left a flat spot just off idle on my bike.

And, in the process, they left the crud in the float bowl? And they didn't mention the condition of the float? Some dealership you have.

Good eye.....I didn't notice that.

Was there water in the float bowl.....was the bike in a place that the water could freeze?

You really do need a new float. When they don't float, the fuel level will rise, and it will run rich. Just a few mm of fuel level can make a difference in the fuel/air mix, and is a way to fine tune the fuel mix once you have the jets as close as you can get them.

Yeah, they are pretty bent up... but i dunk the float in a bowl of water and there were no bubbles coming up, so i think they are still sealed... but i guess that those bents reduce the volume of the floats thus they float less so the carb gets filled more than it should...

No, there wasn't water in the floats bowl, and the bike came from Rome, that is way south from where i live and over there the guy from which i bought it basically kept it in it's living room... what about that Huh

I keep it in my garage so it's not exposed to cold temperature, and even here it doesn't freeze very often...

Yeah, tell me about it... I start to think that they didn't even touch the darn thing; probably they have done some monkey business with some guy that they knows at the DOT without even taking the bike to the exam... i will not be surprised. and they charged me for like a 150$...
