kv qc queries
 

i've got an '86 kv qc,at 2k rpm it doesn't run well at all,jerking about but not misfiring.above 2k rpm it runs normally.it only does this under load:confused:.any suggestions?
also,where is the fuel filter located?
thanks in advance,Mike.

My B2 80 Sport is running rough at the bottom end too.
I haven't really had a chance to investigate yet. I have cleaned the metering unit and throttle body (carefully!) with carb cleaner and that has made it a fair bit better. But still not right.
I've also noticed a fuel leak from the back when the ignition/fuel pump is on. Not had a chance to repair yet. Hoping this will be problem- starved of fuel at low revs and light throttle. Would make sense...
Have you found anything?
