After filling up a full tank I had to open it up. After a certain point with WOT it just seems to be cutting out like im backing off but my foot is still to the floor. Would this mean with the momentom of the car the fuel is getting pushed to the back of the tank leaving the Walbro struggle to suck any fuel (with a quarter/half sure but a full tank?). My car is always regularly serviced (including fuel filter) so im not quite sure what else it could be.Also meant to be running next wednesday but I dont want to damage anything.Cheers Leo Link to comment Share on other sites More sharing options...

Do you have a boost guage? Link to comment Share on other sites More sharing options...

An anti surge tank is good insurance as a lean motor could easily turn into a dead motor. Link to comment Share on other sites More sharing options...

When was the last time this was replaced? Link to comment Share on other sites More sharing options...

The extra boost could be blowing the spark out. Reset to 0.75 to 0.8mm. Link to comment Share on other sites More sharing options...
