General Instructions
Check Box Contents:
Verify you have received two boxes. After inspecting the exterior of the boxes for damage, proceed to
open and examine the contents of each box. Make sure there is no damage and you received the cor-
rect version of the JIMS
®
120“, 131”, or 135” Race Kit. Resist the temptation to open the sealed plastic
bags or the Short Block wrapper. This is to keep the parts as clean as possible. Read red tag!
Start with Box One:
Verify the engine case color matches what you ordered. Use the checklist on page 9 and confirm you
received everything on the list. Close the box.
Box Two:
Verify that the color of the cylinders and heads match with the checked color you ordered. Use the
checklist in box 2 & box 3 instructions on the last page. Do not unwrap the heads. Do not unwrap the
pistons or rings unless you suspect damage. Close the box.
