1403 – 1404 – 9903 – 9904 (500 cfm manual and electric carburetors). We have been in the carburetor since the 1940s and we have an extensive inventory of carburetor component parts that might be otherwise hard to find.
The box is of better quality than anticipated. The parts met my expectations. Price was also a factor. The spring colors could be better to make ID easier.
I haven't had a chance to fire up my rebuilt engine yet, but since I live at 9100' I will be tuning my carb for altitude and performance. This kit gives me a big assortment to dial in for my needs.
