I can't reply to the old thread (must have been before the message board transfer) but I want to give a shout out and thanks to jclovesu and "Flyin' Al" for the tip to tilt a non-starting TW to its left side.
I didn't do a great job of storing my bike for the winter and was having a heck of a time getting it running again. Took the advice, tipped it way over, and bam! Started up the first time. Crazy.
That time of year for a lot of us, so maybe bumping this old topic will be helpful to someone out there.
