I'm trying to track down the cause of my 1293 engine not starting - it appears to be a carburation issue - we started it with one carb mouth covered but otherwise it won't run. My floats (twin HS2)don't seem to be like any of the illustrations in Haynes etc - they only seem to be at the position that they would cut off fuel when they're touching the lid - would this affect the carbs?

John,

 

Had you already taken out the float pivot pin?

No - it has just moved to one side as I waved it about to get the best shot

I'm guessing to avoid leaness (which seems to be my problem)I need the greatest amount of fuel in the float bowls I can get - which this setup is supplying?
I'm fitting AH2 needles rather than the M ones I started off with - how much difference is there between needles?

Blow through the rubber hose as you actuate the float, float up against the lid it should stop the air, float down air should blow out.

I think my question is more is this how the floats should look - no more parts I'm missing or something? I wondered what the purpose of the second hole through the plastic was for?
