I agree and have similar issues as well. I have found it can depend on how far you let the clutch out as well as how fast. It is easier at high speeds and can be done at lower speeds, it just requires a little more attention.
@pletby- If the bump doesn't work, I always use my key as the last resort.
If you are unable to bump, can you use the key? If not it could be the battery or fuel pump issue, but I am just shooting in the dark.
