yes, on the bowl (center section) seven digits starting with 7xxxxxx. (It could have a metal ID tag on one of the screws also). Then look it up here
http://www.carbkitsource.com/manuals/carbmanuals/CM081.htmlTo see what kit to buy. Or tell Orielly's, or auto parts store you like, the number on the carb. ALWAYS take pictures of all angles of the carb and linkage before and during dis-assembly. Do not be worried about the rebuild. It is straight forward. the kit comes with instructions and we will help you. Clean and blow out all orifices, don't loose anything, disassemble in a catch pan, we will explain the plug seal later. As said JB Weld works well. These plugs are where they drilled various holes to create passageways within the carb that could not be cast. Yours will have the press in or spin in kind. The press in kind are the one's that leak the most after time and need to be sealed during rebuild. There seems to be an early monojet (67-7x) and later monojet (80's). You can go here
http://www.carbkitsource.com/carbs/tech/Rochester/Monojet-index.html(same company as other link) and click on each CK number to find a picture of what yours looks like to further identify which kit. He is in Canada and shipping is high.(I have been very happy with his kits) But at least you can identify your carb to get a kit elsewhere if you can find one. The gallon of cleaner to soak the parts in is sold by O'rielly's for $20 and includes a parts basket. 4-8 hrs is enough. After soak, spray them all off with carb cleaner, then brake cleaner, then soap and water, then water, then blow dry. please wear goggles. The gal of cleaner can be sealed and used for other stuff. It is really neat to have a carb you rebuilt that actually starts and runs an engine, you'll see! Get a nice table and chair and good light and take your time. open the carb slowly and peek inside to see how things are positioned. All experts had a first time. And you have all of us. You will learn float level and float drop adjustment. (easy) and how to install accelerator pump. Be sure to do a bunch of searching on the web, you will get allot of knowledge/pictures there so as to be familiar with your carb before rebuilding.
