    Still battling this 250T. Now backfiring in the intake?

    Maybe this is an easy one, but I've not dealt with it. I cleaned, re-cleaned and cleaned again,(right after a good cleaning.
    I have new diaphragms and o-rings throughout, as well as intake boots. It was firing up easily after the first cleaning, yet would bog and die with throttle added. Now it is very hard to get to fire, and when I add choke, it clicks or pops and snaps in the intake Kind of a "castanet" sound. An occasional puff of white smoke will appear below the carbs.
    It will eventually start, but barely. Runs smooth, but very "low" and only with at least some choke.

    any directions I can head?
