Valk mecanic in North Georgia

[FireValk]

My 99 Valk is running rough on acceleration.  It feels like it does when I start to run out of gas and have to switch to reserve.  Is there a mechanic in north Georgia (I live about 30 minutes north of Atlanta) that would be able to help me resolve this issue?  It has 18K miles and has the oem petcock.

pour about 8 oz or so in the next couple of tanks of fuel.  See if that doesn't improve it some.
