Hello all,

This is my first post. i just aquired a rossi .53 and have had problems keeping her running. im using 5% fuel with an os 8 due to the heat here. It seems to be loading up at full throttle and just cuts off no matter how much i lean here out. and it has a hard time idling on the low end as well and does hesitate a good bit throttling up. i see alot of bubbles coming from the fuel line and have checked the tank and lines for leaks. they all check out.. I dont have the stock settings available and cant find anything on the internet as well. Does anyone know a good starting point for the high and low needle to be set ? Would be real helpful to get her tuned in from there. Thanks in advance

The bubbles are you problem. You need to find the source. You say you checked the fuel lines and tank. Just for good measure, replace all your lines including the one in the tank.
