Hi all
Thanks for the information, I will try additional washers under the float needle, however I had 3mm deep of washers under the float needle and it still flooded, but will try some more
I am thinking down the route of the fuel pump pressure is overcoming the float upwards pressure on the needle valve, however not sure how I would adjust the pump pressure, additionally I am wondering if vibration is causing the needle vale to unseat and allow fuel in also
It did not have this issue when I bought it, I changed the diaphragm in the pump because it was hard to start when I was negotiating the buying process and I thought it might be lack of fuel and new diaphragm wound not go amiss, however I have replace the old one and it still floods
Question- when the fuel has been cut off by the needle valve how does the petrol pump function at that point, is it just back pressure from the shut needle valve or is there some king of recirculation of fuel within the pump
All help much apricated
