hi all,

i converted my GQ SWB TB42 carby (on 32inch muddies with 16inch rims) from auto to manual and left the standard 3.9 auto diff ratios in.

since then, i have noticed the car to be slow, engine labouring, having to use a lower gear with excessive engine rev's -otherwise the car will stall in a higher gear.

any info to fix this problem would be great!
