Old Briggs engine help

[Fix'em all 49]

Hi all, can anyone help with the part number of the diaphragm fitted to an old (maybe late 60s) 3.5hp vertical Briggs engine please. It is a white engine and the carb is Not the automatic choke type. I think the engine code says 65902. It is fitted to an early (green) mountfield m1 Tiller.

Hi, Can you check that number again and post the full Model, Spec and Serial numbers. I can't find a record of it.

The 6 = cubic capacity in Cu Inches. Your 5 = a Design number. Your 9 is the Carb Type (9 is a Vertical Pulsa Jet). 0 = Plain Bearings. 2 = Rewind Starter.

 

It is possible the number should read 60502.  The important number in your case is the 5, as it is a different Carb (Vertical Vacu Jet).

If you can post a good clear Picture of the Carb here as well, we can establish the correct original Carb you have and that is not a replacement.

Will then be able to provide a correct part number for the part(s) you need.

then when you found it punch the part numbers in the epay searchbar

Thanks for all your replies. I think I messed up with the first digit of the model number. I have attached a few photos but looking at the diaphragms in the parts list I am not convinced it is the same as any of them. I will ship the carb off & have a look. Cheers, Ian

I think that one is for the auto choke model. The diaphragm is about that size but doesn't have the part that connect to the choke flap. The carb has the small spring and curved washer like the horizontal carbs but the diaphragm is bigger than the 270026 that they use.

Here is the Illustrated Parts List for your Engine-

You can now identify the parts you need and search using the part numbers.

Edit- date for your engine is 2nd Mar 1965

Thanks for your help. Found a comment on a USA site saying this engine was only made for about 12 months in 64/65 so not going to be too many about.
