I have a johnson javelin one hundred model number J100TRLCSC
Serial number J5322059. I can't find a service manual for this specific model number. I assume it's a 2 stroke. What would be the oil gas mix rate? Year of manufacture?
It's a 1980. 2 stroke. Mix the gas/oil at 50:1 ratio. TCW-3 oil only. You can get the original manuals for this engine from the original publisher in Milwaukee, Ken Cook Co.
