I'm sitting here with my stock carb opened up now after checking the main jet.  It appears that the pilot jet is not replaceable?!  I guess it is tune-able to a point.

My stock carb had an 85 jet, but had already been played around with before me. I was just next in line. :-)

by pilot jet, you ARE reffering to the brass rod that runs alongside the main jet???  it is removeable, ivr done it... supposedly thats how i screwed up the other carb.. there are 4 cross drilled holes (2 & 2 )in the head of it that sinks into carb..

Yes, that is what I was referring to as the pilot jet.  It's the closest thing I see to a pilot jet!  It is pressed in, doesn't look like it's designed to be removed.  However, I'm sure you could get it out if you wanted too!  Getting it back in may be a different story!

The conversion shows 163.5 PSI. so you were good when that 11.5 reading was taken. I would strongly suggest going up 1 jet size from whatever is in there now. There are tiny #'s stamped into the jet. If yours dosen't have them, you can bring it to your local guy to have him measure it for you. A little xtra fuel is better than too little

It's easy to tune it back out using the needle. Getting the wot is the most important bit too me
