how come my barry grant carbs won't work on my tunnel ram?
I have a ford 302 motor with a tunnel ram. I bought 2 barry grant 525 vacuum secondary carbs road demon jr. carbs. part # 6282020vm when I get on the gas i get a back fire from the carbs and they are running extremely rich!!! how do i fix this? the backfire is extremely bad when i punch it in 2nd gear. I am have a t5 trans. I have adjusted the bowls and put smaller power valves in it to get it to run more lean. that hasn,t worked.
Question - did you have other carbs on the Tunnel Ram and if so how did it run?
If this is a change of both intake and carbs it could be a larger number of things (the number of items that are possible issues are narrowed if this is only a carb change and it is running poorly)
Generally to run a tunnel ram you need pretty deep (rear) gears and a pretty radical cam. I suspect you know this.
Personally if this is only a carb change I would look for something else at this point - timing and advance would seem to be possible candidates
