Briggs & Stratton 550 issue with fuel

[Corobori]

Winter just ended in my part of the world and I wanted (need) to use my lawnmover again.

As the fuel container was pretty dirty (I know I should have clean it up BEFORE storing the machine) I had to remove it to clean it up and put it back again.
I am not a mechanic at all but I thought that taking a picture BEFORE removing the container was going to help me. I made a wrong move by shooting it using my smartphone's camera and when I had to insert the container again I noticed that it wasn't good enough.

Anyway the situation is that the engine is firing off fine but revs are just going wild and to avoid an engine seizure I have to shut it down. The issue comes from a couple of springs that I know are misplaced. I searched the manufacturer's website to find a manual showing how those springs should look like but couldn't find a way.

Below are a couple of pictures showing the issue. Anybody around with the same engine could help me on this ?

Corobori I will look at mine when I get home later and get back to you, my fuel tank is dirty and has some grass in it. I bought mine used last weekend and I wonder how the previous owner let grass into the tank, surely he did'nt mow with the cap off!??!

Thanks for your help.
I didn't mow with the cap off but I found so much dirt in it I wonder how it got thru. Don't know. I didn't find grass ! :tongue:
