Hi pau13z,

no overevving or shutting off under load.
Will try your suggestion if I can get it to run. If no remedy, I'll dismantle the carburettor or swap it for another one.

Edit: I think I'll empty out this fuel with question marks attached and put a fresh lot in and see what happens.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
