Dear Friends,

I have a problem with my engine (Thunder Tiger 46 Pro) which is not stable at all.
I am afraid that I have an air leak somewhere!

I have the following question;

If I blow in the silencer exhaust whole, air comes our from the carb (till now i think that it is normal)
But If I close the carb whole + the pipe nozzles wholes, I think that I will not be able to blow.

Is my assumption correct? because when I blow, air is going out from somewhere!


Furthermore, while the engine is running and I close the carb intake, the engine goes off after 20 secs, my other engine (also TT Pro 46) goes off in 1 sec!
