Hi Guys,
After 47 years I’m getting back into mini bikes!
I picked up a 2008 DB 30 Doodlebug frame with wheels and bad tires.
I’m looking to power the bike with an old school 5 hp Briggs and Stratton.
Shortly after picking up the frame I found a 5 hp Briggs and Stratton in great condition, numbers 130232 0558 01 80012307.
To my disappointment, when removing the trash pump from the engine, I found that the engine crankshaft has a 5/8” threaded PTO end.
Now, I am looking to swap out this engine’s crankshaft with something that I can hang a clutch on.
It looks like this engine has points and a ball bearing on the PTO side.
I’ve been doing a lot of online research, please correct me if any of the following is wrong:
I will need a Briggs p/n 260921 crankshaft?
P/N’s 260938, 397085 and 492088 will work but the sump cover will need to be swapped as these cranks use a plain bearing? And also these cranks do not accommodate the points plunger, so the engine will need to be converted to Magnetron ignition?
Any other p/n’s that will work?
I am finding very few for sale on eBay and Facebook Marketplace.
I appreciate any input.
Thank you
