Hey guys.

I have a thunder tiger .46 and Im having a heck of a time getting it started.

For the heck of it, I hooked up another tank and it started up. Now the only difference between the new tank and the one in the plane is the new tank has smaller diameter hoses. The hoses on the plane now dont make a "pop" sound when you disconnect them.

Can too big if hoses make the engine not start?? Would this be because there is not enough vaccum?

After the plane started, I disconnected the external tank and plugged the internal one back in. It started up, but I think its only because of what was left over in the engine and hoses.
