03 RX1 Hard Start and Funky Running- Electrical or Fuel?

[03BLURX1]

I have a 2003 RX-1 I recently bought, it has 3,600 miles now. When I bought it the kid said he thought the jets were clogged because it was hard starting when cold and running a little rough. I did a fast cleaning of the carbs and it still started very hard, but only when cold, when it's warm starts right up. I could tell it seemed to be missing a cylinder. We got some snow and I took it out to see what it felt like as I was working on it. Did about a 10 mile loop and noticed occasionally on bumps it would "pop" and the engine would sound perfect, then almost home the engine fired right up and ran perfect, gobs of power. I had trailered it and now it's back to running the way it was. Any ideas?

I must was written this ten time this morning alone. Clean your carbs again install inline fuel filters or you will be cleaning them again. Get some mechanic in a bottle and add some to your gas and use it treat fuel for storage. I would also change the phillips heads to allen head bolts on the carbs.
