Hey I've got it down to 3 potential saw moedwls on my own. 625,630 or a 670. I've spent 2 days young to figure this out on my own. I'd reallye like to know what it is because the piaton looks brand new. And there appears to be a velocity stack with k&n air filter. ImImJu getting my feet wet. This is my second saw. My other is a Stihl 036 pro and imv probably gonna get allot of heat for this but in all honesty it seams this JRed is smoother quicker and sounds much throatier. Thanks for any help I can get

That's a 630 "West Coast".......if original, it will have a thinner cyl base gasket than a stock 630 Super. The identifier here, again if original, is the carb.....625 and 670 have a rubber intake boot and an external impulse line on the top cover of the carb. The 630 has the solid Husky intake/isolation block which routes the impulse corridor internally to the carb. 034 Super and 036 Pro are same displacement as the 630 and thus perform with similar power.
