Brand new, never used custom build losi 3.4.
I bought this engine to use in my personal racer but recently been getting more into the electric side of the hobby so selling it now. Its has been professionally balance for a quicker respond and has been lighten. The carb has also been modify instead of using the stock black dust boot which is very stiff compare to other which limits response time now has a much more smoother one which is much easier on the carb. The engine comes pre-installed with a M2C Racing Quick Change 4 Shoe Adjustable Clutch System. This clutch is completely adjustable to any preference you may want or like, a huge improvement over the stock one. Next the attachment for the losi electric start system was removed ( the attachment is still included just incase you want to use the electric start on it) to lighten up the system and a much lighter pull start system was installed using all original losi parts no knockoffs where used in this build. The final engine was professionally assemble and now is just ready to be used.
