I used the T120A bowl to replace the JB weld-patched T90D bowl. At that point, I knew I wasn't coming away with three carbs. I swapped the best of all parts that matched to the two and now have what appears to be to VERY serviceable TD90D carbs. I spent two hours today at the dunk tank cleaning them with solvent. They look great. Shot the lines with air. I'll measure the floats and set the screws but I think the Banana Bike is going of the Chinese life support and Lori's bike is going back to original as well.
