Hello all 14xx builders- I am glad I found this website forum.
I have recently started building a 14xx having acquired the first 7 kits. I have put the cylinder and valve gear together- the valve chest rods seem to move freely but the cylinder's (with o rings on the piston heads) do not move without breaking my fingers.
Dean and Debbie have kindly offered to test the model on air at the factory once I have the motion together. I am going to take them up on this but don't hold out much hope that this will free things up.
I have tried different o rings and have polished the cylinder inside bores with emery paper and parrafin- this hasn't helped things much.
I fear I may have to seek alternaitives to o rings and maybe a new cylinder block.
From reading the blog a few may have had the same problem. Does anyone have a recommended way forward....
