jerry. the only numbers i can find on prop are p669-3.then 669265.these are bye the prop nut.
compression is 125 across all cylinders.
timing was retarded, now is static timed to 28 degrees.
previous owner tried to make it run ,but gave up. thats how i got it.
carbs were not set up properly the link and sync were way off.
has good spark. plugs somewhat oily.
link and sync done to franks video.
plugs are old .need to replace ,one set is champion , one set is auto light.
i know it has exhaust leak, somewhere at front of motor down low under carbs. choking it out. still need to find source and fix.
also need to check recirculation system not sure what that involves.
what po told me was he put new reeds in swapped out carbs and rebuilt them. tried timing motor with out light . one new coil.
let me know what else i can do.
thank you for your time.
