Older OS FS-120 parts
I picked up an older OS-FS-120 surpass through ebay. Tha version I have has the twin rocker covers. Newer versions have a single rocker cover, I think. Does anyone know what size metric screws were use to hold the twin rocker covers down?
Thanks.

I don't have one of the early FS-120, but it's going to be M2.6 based on all the others.

If you need to get that metric screw size McMster-Carr has that size.
You just need to know the length?
Here is the web page for that metric screw:
M2.6 x 0.45 x ???? what ever the length you need?

I have to use this size screws on the smaller Enya .09 engines (like the .09-II)
