Do you guys know what size the big socket is I need to take clutch apart? I tried to use the socket that works on my 2 stroke 1e40qmb minarelli and it was too small. Thanks.

1E40QMB Thin nut: 38mm wrench/socket size  Thick nut: 41mm wrench/socket size  139QMB Iv seen 34mm & 39mm wrench/socket size You will have to measure across the flats. |

A large adjustable wrench works GREAT in a pinch.

for my 50cc 139qmb, it was a 39mm nut, but I replaced it with a 38mm which is the norm?

39mm is most common. You can measure the nut to find out for sure.
As long as the thread pitch and diameter are the same and the thickness of the nut causes no interference, it doesn't really matter if it's 38 or 39mm.

A cheap pair of calipers will help identify many scoot parts.
Example: Harbor Freight item# 61585
You can get similar units at most tool stores. -Prices and quality vary...
