First Start Up - Engine flooding
Last weekend I fired up my Blade engine with me sitting in the car for the first time. However when I connect the fuel pump (using the bike pump), the
engine gets flooded with petrol to the extent that it came running out of the exhaust!. I disconnected the pump cleaned the plugs, cranked the engine
a couple of times spraying carb cleaner and the engine started into life. It revved/ran without missing a single beat all teh way upto 5K
My carbs are re-jetted (Dyno -Jet) using 135 main jets. Teh kit intructiosn states 2,25 turens for the air/fuel mixture screw. It sounds odd to me as
the original settingwas 2,5. What is the normal setting?
What woudl you think is the problem? I noticed that cylnder No.2 as teh main culprit when cranking teh engine without teh plugs!
Note: The noise was ecstatic as my 4 in 1 is cut into pieces! My mother in law turned all white as she happeend to be at our house 
Regards
Philip

Sounds like you have a leaky carb. If the float in the fuel chamber doesn't seat/seal properly the pump will just kee filling it up with more
fuel. This then flows into the engine and out the far side.

Yup sounds like sticky carb float valves to me too.

[AO|NT]L to that. Float valves sticking open. It could also be that the float height is wrong if the carbs are mounted at a different angle to the
normal bike position holding them slightly open. Could even be just gunge that cleared out with the wash through of petrol.
