hello

I have a second hand YS 140L have no ideea how much have worked, but seems all parts are phisicaly OK...
I mounted it inverted on a Fun Pitts Bipe.

25% nitro + 20% synthetic oil
OS max F plug
18x6 g-sonic 2blade prop
no exhaust improvements
on max throtle around 9000rpm

My question:

is a normal thing to fall fuel drops from the air intake ( probably ) when the throtle is opened suddenly from idle to max?

When idling arround 2000rpm, no drops falling.
On max throtle also no fuel lost.
Seeems ( for me ) not to be rich or lean mix.


Please excuse my english ....

Thanks

JIMMY
