I have a Ted Williams 7.5 Air Cooled (M# 217585911 S# 6D081112) that I purchased about 15 years ago at a Sheriff's auction. The motor ran great for about 5 years and then I sucked up a bunch of gunk into the carborator from a remote gas tank that I did not pay attention to. I ordered some carb parts from Sears about this time (10 years ago) but did not get back to the motor until this year. I found the misc. carb parts but would like to more complete maintenance to the unit. The unit is overall in very good shape as it has been in the shed these many years with all the gas drained from tank and carb. It does seem to have some oil leakage in the lower unit as the outside is covered with oil. I was wondering what year the unit is and if there are any good repair manuals available for the unit. I have applied for membership at the Eska Yahoo group but am currently waiting to get in. Any help would be most appreciated.
