Hi to all, my friend and I have the same problems with the GMS engines. He has the .40 and I have the .47 with remote needle. He has about a gallon thru it and I have about half a gallon thru mine. The engines die at take off, die at full throttle ( in flight) and sometimes die at mid throttle for no apparent reason. High spead needle seems to be too wide of an adjustment and takes about 1 1/2 turns past the peak to choke out the engine at high speed. After reading this posts about the holes not lining up in the fuel inlet of the carb, I took my fuel nipple out and the holes were about halfway lined up. I drilled it out, driiled the fuel nipples on the remote and drilled the muffler nipple as well. I have not ran my engine yet, but I went to my friend's house and told him about this thread. He checked his and his were not lined up either. He drilled only his brass inlet in the carb, no nipples. After a little tweaking, his engine runs mugh better ( on the ground), with only very slight hesitation in transition from low to high.( could be slow throttle servo?) . Looks like the problem has mainly been solved in thanks to the people here. Several people told me to box it up and send it back ( Tower Hobbies). Maybe I would have done just that if I thought it would make it all the way back to China! ( I wonder if there are as many ships heading back to China as there are Coming from China?) The stuff(junk) from China never seems to fit quite right, or am I the ONLY person who has ever had that problem? ( I get tired of hearing that answer from company techs!) I must be what you would call a " Pioneer of Problems"! Now if I can get the rake handle to stay on my new Chinese yard rake, but thats a different forum.


THANKS to all of you in this thread!
