Title: Bing differences
Post by: tomale on November 29, 2010, 10:59:47 PM
I am curious about the difference between a 54/38/101 and a 54/38/123 I think that there are difference in the jetting as in numbering system but will the new ones work in the older carb? and do I need a conversion chart or something to use the older carb. what about performance, do they perform the same?
