Thanks for the replies... yes I have tried everything as previously suggested... that did help a lot but I am just trying to improve the cold starting... on yes, I did not yet try the T connection on fueling.... but will do so... The pump is pumping from the start and squirting out fuel from the disconnected line to the regulator... No one mentioned that they are aware of a screwdriver slot on the side of the regulator....and that slot can be turned easily... Do I have a model that is different? I am not sure but I was thinking that my engine was a Surpass II that I purchased installed on the airplane...
