Carburetor Bore Reamer  Properly Tapered for Box Stock & Modified Venturi
These reamers have been properly tapered to allow anyone to anyone to get the most out of a stock type carburetor, Venturi size is often the most checked measurement if rules require a SA (stock appearing) Carburetor, Getting the MOST out of your carburetor requires you be at the MAX size allowed and at the smallest convergence point (it only has to be the checked size at one very small point) some rules state .615  while others state .650
This tool will allow you to do both or even LARGER  if your rules only state "stock appearing"   all of the made in china carburetors will benefit from a larger convergence point (the smallest point in the venturi) YOU CAN NOT DRILL YOUR CARBURETOR  with a round non tapered  drill bit and get good performance...
for a carburetor to properly draw and atomize fuel it must have a     taper > in and a taper < out.
I use this reamer by hand and  go very slow and measure often,  it is easy to get it larger than you intend. I try to stay just BELOW the size stated in the rules so there is never an issue at the track.
I will pack this well and ship it fast for USPS with online tracking  (sorry I use to ship free but now ebay requires i provide tracking and USPS charges ...
BUT if you buy another item from me I'll refund the ..... 48 states only USPS with Tracking
