carb tuning question

[evilokc]

I believe I have the initial issue solved. I swapped jets and its running great. put about 60 miles on it in the last 2 days and its pretty happy now. next question. I found some trash in the main jets when I changed them. its possible that had always been there but I want to add a post pump smaller filter. every website seems to say 10 or 20 micron. the 10 micron guys says that 20 is too large and the 20 micron guys say the 10 wont flo well enough. what say you guys? 10 or 20 micron between pump and carb?
