Nice work! That's what the dark winter is for.

(I'm not very found of large spinners though, I think the Norvel could do with a smaller one?)

Just a note on the CS carb. I found a fule line a TowerH which is 2x4 mm (if I remeber correctly) and that had a very nice fit. Also an airbleed screw can be fitted but it is a bit tight. Just drilling a small whole though will help with the low end.

On a converted TT07 I've tried OS#P3 and P7, I found the P7 a bit trickier to start on (colder) but it ran nicely once running. Can't decide which one to use yet...
