ok my carbs have always done this. first of all last week we completly broke them down and cleaned them up they run like a champ if im on top end but if im lugging up a hill and decide to get on it they wont pick up it just is verry slugish and never gets going what could cause this also they are dual webber 40's i believe my main jets are 50's |

Give more info on motor. If the carbs idle and run good I would look at other areas before condemning the carbs. |

check fuel pressure then float levels. I believe you want around 3 psi... NO MORE!!! I always run the floats as low as possible. keep lowering them then run the buggy hard for as long as you can to see if you run out. once you run out, raise them up a little and leave em there. |

When you figure it out let me know because my 2 seater has always done that even with a 2500 on it. |

i dont know thats why i ask lol i just said what i think it might be but want evry suggestion i can get but when i had the lower geared trans in it still did this so thats why im not thinking its my trans/tires and its not a sputter it just never gets the rpms up on bottom unless i turn it up befor i hit the hill |

Was the lower geared tranny a 4.83. If so thats not enough. To fix your problem you need a 4.10 or 4.25 first gear witha 5.42 ring and pinion and that will fix the problem. |

The 45s cleared up alot of the black smoke that it had on bottom dont have a hill to test it on so will have to wait and kevin that setup is my goal im putting back money to buy what I need for the trans |

Check your air mixture screews. If you have them adjusted more than 4 turns out to get it to run your idle jets are not big enough. Borrow some 60,s and readjust your air mixture screws. Float levels have to be correct. Black smoke could be too much pump shot. |

Accelerator pump is what he is talking about. Have you checked your timing and distributor to make sure the weights are swinging out. Lastly check for vacuum leaks with some WD |

If you have 40's maybe your venturis are too small. Maybe not. Do you know what they are? Having small venturis will cause it to run rich. (not enough air) |
