    1981 Johnson 115 voltage regulator

    1981 115 voltage regulator, not sure how it works or what it is for. Will it affect the charging of the battery if it goes bad? How is this component tested to see if it is good? Does this act more as a resistor seeing as the purple wire is keyed power and yellow is on charging terminal. Thanks...

    Does Attwood make a manual venting fuel cap for their 6 gallon tank? The EPA cap that comes with them new does not properly vent the tank. Any suggestions on venting that EPA cap if they don't make a compatible manual venting cap?

    Carb high speed orifice #'s

    Was looking up carb parts for my 1981 115 Johnson and noticed that the same year 90 hp has a larger high speed orifice number than the 115. Wouldn't the larger hp have a larger orifice number? The 115 is a size 60C and the 90 hp has a 65C while the 140 hp has a 67C. Isn't the higher the...

    Suzuki Oil Injection Pumping too much

    My son has a 1986 Suzuki DT/150 that is getting too much oil on the high and low end. Being a mechanical oil pump, can it be disassembled and reassembled in such a way that it seems to always be wide open for oil distribution? He just got the engine and it keeps fouling new plugs within twenty...
