@mr. Phil,
I have to admit that I feel myself "lucky" for two reasons. The first is that the time when I was looking to get a local C15 or a C15A from a very few and tired remained here, appeared out of a sudden that HUW for sale infront of me, and the second is that at the SAME time YOU have started the overhaul of your legendary HUP, so your progress -presented so wisely at your site- is a big course of lessons, not only for me, but for every MLUer..
Feel absolutely free to make any comment you like, I will read you with great respect...

We decided not to remove the cub, before uploading the engine. Made a mistake?
