13. Muffler: Stock OEM muffler in unaltered form must be used. If any doubts about the integrity of the muffler should arise, simply cut the muffler in two, to determine legality by comparing to known stock muffler.
14. Governor: Governor gear, arm and linkage must remain intact and functional.(As of MARCH 1st, 2024 competitors may utilize the DUCAR OEM rev limiting ignition coil(Part # 212-1260R) as an alternate to the stock OEM governor. You may remove the governor assembly completely and plug holes, leave governor in place and wire in the open position or leave the governor assembly in stock form. Regardless of method chosen, the engine still cannot free rev over 5500 rpm max.) Track may require engine to be free revved on the stand to a certain RPM to determine if governor is properly functioning. (5500 rpm max for example) It has been our findings that some engines surge and some will not. We do not require the surge because in stock form the engine will perform best at 5000 rpm or less. However, this will be left entirely up to the race promotor/tech.
15. Gas Tank: Stock tank should be removed and an auxiliary tank mounted in the floor pan should be used. A top plate and fuel pump are allowed with the pump be pulsed off the valve cover only. (Track Option) Utilize stock OEM tank with the vent tube unplugged and up to 4 - 1/8” holes in the fuel cap for venting.

17. Chain guard, throttle linkage, top plate and fuel pump are the only aftermarket parts allowed on the engine.
18. There is no longer a claimer rule. The engine in question must be protested by a competitor or subject to tech by the track if the promotor/tech deems necessary. The protest will be $200 and acceptance fee will be $100.
19. If there is any doubt as to the legality of any part on a Ducar 212 engine, the competitor has the right to file a protest with the track/official. The part in question can then be shipped to DynoCams for review. Please include contact information for the promotor and we will contact the promotor with our findings on the legality of the part in question in a timely manner
