recurring (non) carb freezing??...kinda long..:(

i had a problem with what i thought to be carb freezing a couple weeks ago. i hooked up a home brew hot air induction hose (my factory hose was missing) had some problems with the hose itself, replaced it with industrial hydraulic hose (the hose itself should be good now) and havent had any problems since....till today, when i had the exact symptoms occur as last time i made the trip and thought it was the carb freezing up. the warm air valve opens as it should (as far as i can tell; when i pull the warm air hose, and its cold out, the valve is unless it closes once i start driving...)
but the warm air hose is very warm when i stop, so it seems that warm air has indeed been drawn through it.
do you guys have any other ideas as far as what could be causing this?
ive only had the zuk a couple weeks, so i dont know if it does it when its warm out too.
it runs fine for a couple hours, then has a huge flat spot (from about 1200-4000 rpm) but pulls ok - a little weaker than usual, but smoothly - above that and idles perfectly
i thought it was because the primary circuit on the carb was freezing up, but once the secondary opened, it started running ok again. but now its still doing it with my warm air hose, so im at a loss with it.
any ideas would be GREATLY appreciated
i was under the impression that the coil, plugs and plug wires would either work or not, but could they be causing these intermittent problems? if it falls flat and i let off, it drops to a smooth idle, which lead me to believe that it wasnt a part of the ignition system.
thanks again guys
not that this point has anything to do with it, but its a shame im having this problem because i was once again quite pleased with the performance of the (for now) nearly stock zuk -my friend in his lifted jeep was less pleased... [img]images/graemlins/grin.gif[/img]

Try puting in some gas line antifreeze. The alcohol based type. Sounds a lot like a bad load of gas, or
condensation in the tank. i have switched to Unoin 76 which in CA is gasahol, and I almost never get
these intermitant starvings for fuel, and when I do its over in a few moments now.
