[TR] Are there any new hi-tech cheap gadgets I can buy to get my fuel mixture right ?

[Bud R]

I have an older version that works fairly well. I used it to pass  
emissions testing and it was accurate enough for that. I did have to  
watch moisture buildup on the little plastic part that the flow passes  
by as it would start to give erroneous readings if you didn't wipe it  
off regularly. Maybe the newer versions don't have this problem.
