crankpin
Husqvarna
B Class
I've done this a million times, but this carb has given me some grief 
First, the float pin had seized and was a bugger to remove, next the plunger on top of the float valve was seized. luckily I had a spare.
The main jet was blocked solid (a 195) and I could only find a 200, so that went in.
This is where I may need your collective knowledge, the manuals I have for this model are more than a little vague when it comes to float level height, so I set it as per most carbs with this type of float valve, level floats as they rest on the float valve without depressing the plunger (2nd image). Is this correct?
Next, reassemble the carb with new o rings, and test it off the bike, ensuring a good dribble of fuel left the carb when the tickler was depressed. I then installed the throttle valve and fitted the carb to the bike, and re-test, perfect, you might have noticed that I swapped the carb flange bolt for a socket head.
All that's left now is a proper running test and plug chops ( I hope)
Oh, while I'm typing, is there a paint which is fuel resistant?
I normally use PJ1 fast black with good results, but this time, the paint goes soft on top of the engine where the carb drips after using the float plunger.
