I have a parker duofold (international size) from the early 1990s, with a Medium nib. Is there an easy way to increase ink flow?

I have a Duofold Centenial with a fine nib and it had good flow but I wanted a wet writer. So I increased the depth and width of the feed channels and I also adjusted the gap between the tines to give maximum flow without sacrificing smoothness. Just remember when you take apart your pens and modify and make adjustments, you are probobly going to void your warranty. exercise caution!!!
