[AT] Carb problems

[henry miller]

In my experience it is easy to rebuild B&S carbs. A $20 carb kit and a free hour at a clean table and done. Of course this assumes you can find a carb kit... write down the model number andd serial number (for good measure) and see what your local small engine shop has in stock. 

I'd hate to replace an otherwise great B&S with ball bearings and cast iron sleeeve; with a new engine with sleeve bearings and no sleeve. It can be really hard to know if you are getting a good new engine sometimes.

Second...

A while back, I posted a question about David Bradley tractors. Well, I 
bought two, one is the very first model they sold through Sears, a 5751 and 
the other is a 1955 Super 3.

The Super 3 was re-powered with a Briggs Model 14, 5hp engine.

This is the first time I have ever worked with lawn & garden-sized engines. 
The carb on the Model 14 has some issues. After checking fluid levels and 
setting the carb adjustments per the manual, I opened the petcock on the 
fuel tank and saw gas leaking big-time from the carb.

I removed the carb and discovered:

1. The threads in the opening of the carb where the brass needle valve 
screws in are stripped. I could see this by the way the brass slotted head 
was chewed up that someone forced the needle valve in there. I managed to 
get it out but can see that the threads are totally messed up. This is not 
the source of leaking gas but is a major problem

2. The float was not sticking and it does not have a hole in it and it was 
adjusted properly and everything looks clean. I did notice that the brass 
seat that the needle pin goes into was also chewed up. There is some reason 
the pin is not being fully inserted into the seat, which I believe is the 
cause for the leaking gas.

I am pretty sure the needle valve opening will need to be repaired, 
something I am not equipped to do.

Are there Briggs carb rebuild services out there or places that sell rebuilt 
carbs? I know I could buy a Northern Tools replacement engine for under 
$200 but would rather get this old engine running. Thoughts?

Thanks!
