I was really hoping to see duct tape and chicken wire, but pull ties
aren't near as shade tree!!! Duct tape doesn't stick to greasy dizzy
housings either but the pull ties might. Skinny bungie cord and
thick rubber bands? Maybe one of those rolled edges on the open end
of a Nitrile glove, but it might be too big around
I epoxied one back in some years ago, but I wasn't on the road at
the time. When I hgot the money, I bought a new one and yes, my
symptoms were identical with the dropping tach. One things pretty
certain, when the tach jumps around and your right foot's not making
the changes, ignition and electrics is a great place to start
sniffing out the problem.
