Runtoeat Posted February 24, 2012 Report Share Posted February 24, 2012 After my 5 year rubber change, I note that I now have fuel which comes from the intersection of the air inlet hose and the carb inlet. It drips down from the hose clamp and drips into my drip tray. Both carbs are doing this. I had the carbs completely rebuilt by a major parts supplier. I had no drips before the rebuild. My friend's CTLS has developed the same probem but on just one carb. In order to leak here, the fuel has to come from a point insdie of the carb and then flow against the incoming air and travel upstream towards the inlet of the carbs. I was told by a Lockwood tech that this can happen if the needle valve is not completely shutting off. He said to remove the carbs, hold them upside down so the floats are shutting off the needle and apply 5 to 6 psi and see if the needle valve holds this pressure without leakage. I have not tried this because I'm still burnt out from doing the 5 year rubber change. It is not a large leak and basically just leaves my hose clamp and drip trays wet after a flight. Has anyone else had drips from this area. If so, were you able to eliminate it? Link to comment Share on other sites More sharing options...
