Apposed problem
« on: October 01, 2008, 02:42:36 PM »
  My twin ran great untill I parked it in my shop. I got back on it 15min later, it cranked up fine and I drove it out back and I hit the throtle and the motor deided.  It cranked back up fine but it would only idle. I drove it back to the shop and I did everything I could think to make it run right. I put a GOOD carb on it, re-torqued to head bolts,checked all the bolts on the intake,cheacked the flywheel key. But now it will only fire on one clyender. Is it the mag?

That's what happened to mine, the switcher in the magneto decided to quit and was only firing off of the top cylinder so i replaced magneto and it ran perfect.
sit down, hold on, shut up

Are you running mod-x instead of sportsman now?

ohh it's spelt Opposed twin  ;)

Ohh yea, I'd think its the coil that’s needs replacement, I had a flathead 12 hp that had a very similar problem. Any time it would get warmed up it would not run worth :censored:
