to maintain these oldies the Johnson maintenance bible is available on line for download a 400 + page manual that covers all maintenance aspects od RD 13-15 for the 1952 and 1953 25 hp’s
do expect to replace cracked coils ..if cracked,… condensers … impeller… points may just need a clean-up
before spending $$$$ on parts and all….. check for low compression in case it was run hot , could be just a head gasket or a major undertaking. Look/consider the general aspects … was it neglected overall or pampered for 70 years ? see a nice 5.5hp
I refurbished
check gear oil for water (GC may need a reseal) … it is all in the book !
J&E and cousins anyway…. so the Johnson book will cover what is needed carb magneto gc ph wise etc…
