Yeah the new VX18's have different pull starts on them. The newer ones are 1" bolt pattern and the older ones are 1 1/4" bolt pattern. My Lightning and both Tornado's have the 1" and I noticed the Volcano I just got has the older 1 1/4". I will have to find out if they have a drill start back plate with the 1" pattern.

How bad is the pull start broken, any chance you could rebuild it to get you back up and running??
