Fix'em all 49 #1 Posted September 28, 2016 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. Share this post Link to post Share on other sites

Fix'em all 49 #5 Posted September 29, 2016 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 Share this post Link to post Share on other sites
C-101plowerpower 548 #6 Posted September 29, 2016 looks like one of these should fit # 494622 http://www.ebay.com/itm/Complete-Carburetor-Overhaul-Repair-Kit-For-Briggs-Stratton-494622-/231967856508?hash=item36025c977c:m:mD1O5pZEATeSzWdPGt5NIPQ Share this post Link to post Share on other sites
Fix'em all 49 #7 Posted September 29, 2016 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. Share this post Link to post Share on other sites
Anglo Traction 1,016 #8 Posted September 29, 2016 Here is the Illustrated Parts List for your Engine- Briggs 82902.pdf You can now identify the parts you need and search using the part numbers. Edit- date for your engine is 2nd Mar 1965 Regards Share this post Link to post Share on other sites
Fix'em all 49 #9 Posted September 29, 2016 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. Share this post Link to post Share on other sites
