Can anyone identify this tool?

It belongs to my grandpa who rode competition trials in the 1950s on a BSA gold star.

Thanks!

the hook thing reminds me of a spring puller. the carb is part of an AMAL "remote float" type

Yeah, teachers use them all the time, modern equivalent of chalk.

Used to check spring tension.

For throttle springs I guess?

It makes me think of the old "pencil in the plug hole" method of setting ignition timing. There were some creative special timing tools available in the sixties when I first got involved with the Brit stuff.

so....I'm gonna guess it is a tool for setting or checking ignition timing.

But no one would want to time their bike with something like that these days. A 1" dial indicator setup is the way to go.

Nowt wrong with pencil down the hole for an old British bike- fine for my side valve Ariel & my Panther.

I stand so corrected for casting aspersions on the "old" ways that have served for so many years. Thanks for carrying on with the traditional methods.

But I'll stick with using a dial indicator myself because they are so much easier for my old eyes to see. .
