I have a saw the number on it is 1983 0 05243. I can't find the compatible model while looking for parts. I need an oil tank cap and a chain tensioner. Replacement parts has some listed but I'm not sure that they are compatible
I'm sure that it is a 630, thinking it's manufactured in 1983. But can't find any description in listed model numbers with a similar manufacture date. I'm pretty sure I've had this saw since 86 or 87. And a lot of models are described as "super"Does no good without one or more pics
