Hi,

There is another thread a while back on RCU dedicated to solving GMS .47 engines that were difficult to get running. In the end, after many suspected fixes, the problem engins seemed to be isolated to the line up of the hole in the fuel intake to the fuel intake nipple.

The thread is here:

If you have any problems with your engine, you may want to read through the thread, the final fix is there with pictures.

Hope this helps.
