Jred 630 cylinder upgrade to a 670

[mifirewoodguy]

Will a JRed 670 cylinder and piston be a direct swap on my 630? any carb readjustments or mods needed? And what does the (super) indicate on my 630??

To put the 670 cylinder on, you will also need the intake as they are different.

The Super just means it's newer than a 630, although there were changes over the years, but don't compare directly to the 630, Super, and SuperII names. For example, the chain brake had three styles, the original 630 had a steel handle and then the plastic handle (old style) was used on the 630 and Super, and the new style was used on SuperII (and maybe the Super as well).
