Pulled my carbs apart for service & inspection.
Found the pistons galled about 1/3 in circumference at top and as you look
down into the bore about same condition. The actual top where the piston
slides into looks ok. is it required to change both? Engine has 341 Hrs.
And according to a/c logs no service ever performed prior to this.
Any knowledge on this???

Thanks in Advance....
