I have a new os 46 fx engine on a Hobbico Superstar 40 with a fuel problem. I'm getting plenty of bubbles in the fuel line between the regulator and the carb. I just changed all the fuel lines in hopes that the problem will be corrected (I'll check tommorrow). If it's the tank it self, I'm really not sure how I can fix it without ripping some of the balsa out to make room to pull it out.

Here's my question. Is it possible to get air in the line from the reg to the carb from anywhere other than the tank or the fuel lines? It seems logical that that would be the only way to get air in that line, but let me know if I'm over looking something.

Thanks,

Dave
