<VV> Carb repair update

[Stephen Upham]

I did not see a "distinct squirt of gas" when I used the crossover  
tube to give it gas in the accessory mode; just a cloud of vapor near  
the venturi on the right.  I do know that I have a tear in the left  
carb paper gasket (the one on top of the two that connect the carb to  
the head).  The tear (1/8 ") was on the area that fits around the  
mounting pole and to the outside and since I don't have any  
replacements and it didn't look like it was a critical area, I went  
ahead and reinstalled it.  I'm pretty sure that the vacuum balance  
tube is ok (I put screw type clamps on them).  How can you detect a  
vacuum leak at the base of a carb anyway?  Remember, I can't even get  
it to run, now.  I do know that the carbs are set tight to the head.   
I'm going to try to adjust the idle adjusting screw as mentioned (and  
slightly means... 1 turn - 2?) , but it will be after several "honey- 
dos" and so may end up being tomorrow.

Thanks for all the advise, I'm sure we'll soon solve this mystery
