I thought about the fuel system also,, but finally found a way to make the La. 46 preform. I replaced it with a Saito .56.

The saito ran for 15 minutes out of the box and was cycled and cooled. Then after the 15 minute run test flown. Ran flawless out of the box inverted and turned 10,200 rpm w/ APC 12x7 prop on 15 % fuel.

Too bad the La did not run well inverted I would have kept it in the bird due to $$. Have fun flying.. Jim
