Technical Panda 30 question

[the hobbler]

Hi DW, with that date stamp I would expect to have valve stem seals on both valves. Your engine man will find that there is a large amount of material to be removed from the inlet tract and exhaust tract to smooth things out, I would be careful how wide the inlet to carb surface is made before you have your carb manifold to pair with it.

A part of the inlet tract to pay particular attention to is the ridge just behind the inlet valve. This needs to be smoothed out; quite a bit of material can come off it
