ORIGINAL FACTORY REPLACEMENT PARTS
This is how our part numbers work
like... 12-0902
and you can still search by old part numbers in our cart.

the first digit of the last 2 loosely designates ...

0 aero - or sets

1 heli, car - or head related

2 marine - or back cover related

3 muffler related

5 control line

6 fuel tank related

7 timer related

8 carb related

9 part sets

this last digit is just a variation of the part
 
Sometimes parts from different engine families are shared between families. Usually the first family to use the part will hold the family identifier. Like a 85-0102 is a idle needle for a RJL K.61 but it also fits a older K&B .61 and .40 carb. Since the RJL used it first the number retains the -01 in the K&B .61 and .40 parts lists.
Using this system you can sometimes make up a number and find the part you are looking for. Lets say you want a crankshaft for a K&B Sportster .20 - If you go to our shopping cart all you need to search be is 17-56 (omit the last 2 digits) and the result will be all the crankshafts fitting that engine family. This works only if the parts are not shared across engine families.
 

Now with the addition of FOX and WEBRA we're adding some new numbers variations.

Fox numbers in the 1950's were very simple 4 digit. Then he went to a 5 digit. All CL engine parts started with a 1, all RC engine parts started with a 2. We are dropping the first digit and adding out part category identifier to the beginning and mostly leaving the rest of t he number the same.

Webra numbers used a / which is not computer friendly in some cases. We are replacing the / with a - So part number 1024/10 will become 1024-10
