Hello everyone,
I have just been going through some old 1/2A stuff. I have an old Wen Mac Mk 12 without a needle valve. Does anyone know the thread on these NVs? I believe them to be the simple wire type with a thread cut on them. Impossible for me to measure the tpi on the inside of the spraybar. Can anyone help?
I also have a couple of OK cubs. The first is an 0.99 in excellent shape , just requiring a prop bolt. Being based in UK, I don't have many small US standard bolts, so does anyone know what size prop bolt this takes?
The other OK engine is a bit of a mystery, it has 0.6 (yes 0.6 NOT 0.06!) cast on the bottom of the crankcase. It also has a spring starter (defunct) and no prop bolt again (size? it looks a tad smaller than the 0.99 bolt). It has a simple metal tank on the back and the extended venture and it is FRV. Nothing in the Tim Dannels Encyclopedia seems to fit this beast, unless it is really an 0.049 or an 0.074 in disguise! So if you can identify the prop bolt size and tell me if the spring starter can be repaired (I am fairly handy at repairs!).
Happy New Year,
Andrew.
