My son just bought a brand new cen matrix fte cheap as by the way. After finishing putting it together it was time to run it and a brand new motor in ( an mit b5 blue edition) Running it in using heat cycle method. During the first tank I noticed a lot of air bubbles going thru the fuel line which in turn made idle go up and down and in turn made the engine keep stalling ( Its a tight engine but ive run in a lot of alpha engines with great success)
Whats the problem never encountered it before.

Sounds like you have an air leak somewhere. Might want to check your tank and lines.

This is almost always a leak in the tank. The small piece of fuel tubing between
the nipple and filter/clunk. Does the problem go away with a full tank? If it goes
away when you have a full tank its internal. If not then there may be a leak at
the fuel nipple or line.
