RE: engine causing grief!!
The Tower .46 is NOT an air bleed engine, it is a dual needle ABC engine which is FAR more powerful than the .46LA.
The .46LA ( and all of the LA's ) are air bleed.
Someone here once said...
"The O.S. .46 LA engine is the BEST .32 engine I've ever owned! ".
He had it right, it is a great .32 engine... in terms of power.
