Briggs carb re-built kit

Got a carb rebuilt kit for my 42B707 and have issue with needle.

The needle included in the kit was a solid metal were the one that came out had a rubber type tip.

Now I used seen the solid needles before but the kits always included a seal that goes into the needle seat to assure the gas flow shut off when the float pushes on it BUT this kit I received included no seal. I was careful opening the kit so I'm almost positive I didn't lose it as the one I have seen are cylinder in shape with hole in the middle where the needle tip goes into.

Without having the seal I just reused the old needle but has there been a change in the carb kits that I'm unaware of? I don't have the kit number with me right now but I'm sure it was the right one as all the other gaskets and parts matched up.

I'd say you made the right call, as long as you weren't having fuel level issues to start with. The metal to metal needle & seat assemblies have always given me the most fits on small engines. I would assume (I know, that's dangerous) that some of the suppliers (can you say off-shore?) are switching to the all metal designs for cost reasons. I haven't had any bad results from using the Viton tipped needles as of yet with the E-gas.
Madmantrapper, have you ever tried to find one of those o-rings when it has flown out of the carb body just after you prod it with a pick? They bounce, they roll, and they can travel a good distance through the air.
Did I mention they can travel a good distance? And that they are small? And that my eyes are old? Kind of like looking for a needle in a hay stack... Why are you looking there? Because the light is better. Makes just about as much sense as looking where you thought it dropped to the ground. Did I mention they are very very small?
Took hours. But it sure worked good after I put it in place.
