Carb Stamped ID Number vs. Casting Number on Back of Main Body

<< < (2/2)

Cliff Ruggles:
If you have the means, put some pics of the stamped number up here.  I see a LOT of restamped 7040205 and 7041205 carburetors.  They must be in pretty high demand these days.....Cliff

Cliff:  Here are a couple of pictures of the stamped number and one of the rear of the carb.  The fuel inlet threads are stripped out and the fuel inlet seat threads were a little messed up too.  The seller said he bought a bunch of carbs that had been in a machine shop for years and swears this is an original.  The patina on the carb and number stamp area look old.  The jets are frozen in the body but are the correct #77 jets for this carb.  One would think that if they were going to restamp a carb, that they would have used a much better core than this one. 

Thanks for looking.  I plan on sending it to you to have a heli coil installed for the fuel inlet.

Cliff Ruggles:
Doesn't appear to have been altered in any way.

We install heli-coils and turn them around in 1-2 days....thanks....Cliff

Cliff:  I sent the carb body to you and it should arrive this week.  Thanks for your help.

Cliff Ruggles:
Sounds great...thanks....Cliff
