installed a set of brand new toomey t5s a few days ago and had it jetted nice and everything and it was working awesome and pullin hard, but today it was workin like crap from the second i had started it. it has trouble opening up unless i clutch it and in 5th and sixth gear i cant get it to open up at all. today was raining and pretty damp if that might make a difference. tried new plugs even though it was running on two cylinders. stock except for t5s, uni filter and no air box lid. never checked compression yet but was working 100% when i parked it.
