Well just out of sheer luck I guess when I modified the mounting plate to allow me to fit the G26EI in my H9 Taylorcraft, the top holes on the 33GX when inverted line up perfectly. My only issue is that the centre line of the crank is now 2 or 3mm higher then that of the Zenoah - which was spot on in line with the laser etched marks on the firewall.
I guess I can run a bit larger dia drill through the top 2 holes to allow me to lower the engine a little, but really only want to do that as a last resort.
Is this going to pose too much of an issue?
Also I haven't had a good look at the carb setup, but would it be possible to flip it around 180 degrees to get the throttle lever on the other side?
Thanks
