Title: Valve to piston clearance- lightweight spring?
Post by: Jonny Grigg on June 24, 2014, 20:22:02 pm
Hi,

I need to check my valve to piston clearance. Does anyone know where I'd get a lightweight spring to just hold the valve on the seat? I'd prefer to do this rather that use an outer Chevy spring if possible.

May sound like a stupid question, but what spring could I use? Is there something out there specific for this or is it another "make do"? I might be reaching in the loft for my old R/C car stuff from when I was a kid and use a cut down shocker spring unless there is anything better out there......

Thanks for the help.

Jonny

Great idea! I have one of those ;)

Jamie mentioned the rear main to you? Hopefully Wayne will have that turned down in the morning and we're back on it......
