Title: Re: 1932 Model 9a - Telltale Spring
Post by: Ian Roberts on October 22, 2025, 09:02:21 AM
Hi
I am coming to the end of my Sunbeam rebuild and have another question/request.

I appreciate the topic of telltale springs has been discussed many times.

As the oil is the life blood of the machine, I would like to confirm the telltale spring I have is correct in length/compression to do it job of diverting oil from bottom end to top end.

The only way is to compare the two springs I have is with a known working example.

My location is Cheddar Somerset, is there a 9a owner in the vicinity I could make this comparison or could I post my telltale springs further afield.

Thank you for your posts assisting me in the past.

Regards Ian
