Talked to Bob Davis today. looks like TT did an upgrade on the 07, it was a wimp. Bob is going to see if how it is as a diesel, it is a screw on head he has not decided on a complete screw in head or a button iinsert, Don't get you hopes up yet but this could be an answer for a half A diesel a little over 3oz if all goes well martin
would maka great park flyer conversion, to complement the OS10 and TT10

After Bobs move th a bigger shop, the CNC, set up, he has decided to take a week off .Have fun Bob
