Im having a horrible time with all of the repairs and things that are going wrong with my cross tiger. Now the engine fires up but when i put at full throttle it won't go fast at all it just bogs down and then it just dies. Its not too rich either. Im new so i might be doing somthing wrong but im so confused and angry with this nitro rc car.[][]

Sounds like you may be way too lean. Try richening the HSN a bit and do a high speed run see if it stays running longer.
