Sorry to drag a really old post up. But I'm getting really f-cki-g mad with this carburettor now. Prepare for a rant.
I'm not new to messing with bikes, in fact I've messed with them since a teenager, I used to race. I'm nothing like new to carbs. I've worked with Dell'orto, Dell'orto copies, Amals, Micarb.
Well we all know the Micarbs can have there problems. But I never expected it from a flipping Japanese genuine Mikuni.
I've never had problems with Dell'orto or Amals. But the idle circuit ( pilot jet ). Just wont fucking do what it is suppose to do on this bleeding TM32-1!!!!! I've tried everything. Checked for air leaks ( none, not even slightly ). I've tried 27.5, 30, and 32.5 pilot jets. They all spirt back through the carb, some worse than others. I can barely get a definite increase in revs when adjusting the pilot screw. I've tried the carb with and without the air filter...No real difference.
I am this close to buying an Amal. I've already made one phone call with my local classic bike dealership and parts specialist. If it wasn't for the fact the Mk1 Amal Concentric Premier was out of stock in 32mm I probably would have already ordered one.
Remember this is for a Asbo 19.
