I am nearing the end of my racing season with my LO206. How do you get the 206 rebuilt? Do I need to send it in to Briggs?

The NHRA and IHRA have approved the 206 create what can be done to the motor to run in the 7.9 class without getting into the bottom end of the motor? Also are the valves the same size in all animal motors: ie world formula?

Asked by: Muncher
The 206 will not run a 7.90 without modifications. General feedback to date puts the engine a touch under 11 seconds in 'standard' trim. This is, of course, dependent on driver weight, exhaust, and so forth. The valves are the same as in the World Formula with the exception of the keeper height. The World Formula, due to its dual valve spring set-up and larger cam, has a higher slot in the valves for the keepers to allow travel without binding.

I just purchased a new local 206. It will not exceed 2500 RPM. I have changed carb also have changed jets two sizes higher and two sizes lower and still I cannot get more than 2500 RPM's. Is there anything else that could be stopping it from Reving?

Contact us offline please. It could be a host of things engine and not engine related.

I have noticed their are different colored slides for the walbro carb. Can someone explain what they are?

Asked by: Muncher
Our Walbro colored slide system consists of various slide lengths that are anodized for ease of identification. The beauty of this type of restriction system is that it controls throttle opening without impacting the air fuel ratio. Restricter plates impact the air flow causing rich and lean conditions throughout the rpm curve and this is why carburetor setup is more exotic and engines are limited in the power range they run well. With our slide system a racer can start our with a slide and simply increase performance by changing out the slide during their career. When a restrictor plate is changed the entire carburetor setup changes costing unnecessary headaches and cost.

Looking for a rock solid HP motor to run at the local track that will hopefully last years. On features it says that your motors feature a "racing reinforced cylinder." Do your cylinders feature a cast iron cylinder sleeve for long-wear & durability?

Asked by: Gearhead
This cylinder is solely used in racing. It features a cast iron sleeve, reinforced bearing pockets, and aluminum ribbing in stress areas for additional strength. The cooling fin design and jug are strengthened and changed for increased cooling as well. Purpose built all the way!
