Gents, buddy of mine asked me to check out his GT235(B&S 18hp v-twin). Runs good for about 10 mins the bogs down and runs rough. This afternoon i checked it out. Once it started running bad, I pulled the right plug wire, and nothing happened. Pulled the left and it shut off. I also put a spark tester on each plug. The left had a good strong spark, the right was weak and inconsistent. I'm thinking coil, what say you guys?

I agree with you there, sounds like a weak ignition coil. Also possibly a spark plug wire going bad.
