1 - Go Here http://www.ironbaymodelcompany.com/W...Regulator.html Purchased advertised item or a cline model (same thing different company).

2 - install on firewall near carb with silcone RTV like you use on a car.

3 - install the check valve in the muffler pressure line.

4 - put clamps on all fuel line connections

5 - start engine (will take 3-4 seconds of cranking to create pressure in tank).

6 - go thur adjusting the engine (needles will take a lot more turning to make a difference).

7 - go fly plane your flooding problems are over and you will not be tweaking on the engine all the time.

This is the only solution to you problem that is practical. My tank is in the canopy on the CG so it could not get any higher and I have no flooding and haven't touch my needle valves in weeks even with an almost new saito thats still breaking in. Hope this info helps.
