I just changed the spark plugs, and it turns out the prevouis owner was running the completely wrong ones in there. On top of that the plugs had a small amount of metal shavings on them. One spark plugs gap was actualy bent down quite a bit. I put in the proper plugs and for the first 30 mins it was running great. Now it wont run over 2100rpms. What could be the problem? Thanks

Just checked the plugs again. The plug that was put in that went into the one that came out badly, is already in bad condition. It has (which seemed to be) water on the plug, and quite a bit of it. From the little i could see into the hole of the spot the spark plug goes into, it seemed dirty. I also checked to see if that plug was getting a spark, it was. Also, felt for compression with my hand, compared to the other cylinders, there was practically none. Blown cylinder?
