i just got my new s/p12a turbo motor from rotary engine specialist in new zealand. It started right up and ran fine, I drove it for the first time yesterday. After about 11 miles it started backfire and spuddering. I started checking all the sparkplugs. When I pulled out the number 2 trailing plug, the center electrode came out with the spark plug wire. I changed the plugs it started again, and was still spuddering. Could someone help me with this? Could it be timing or something? Please help...

thanks in advance...

 

Here's a free bump for ya man. Sorry I couldn't be more helpful when you called me. Its kinda got me stumped. Glad we at least got it running to begin with.
