I often see jargon or many abbreviations when people post and it's taken for granted people understand what they are talking about. Sure if I'm here long enough, like several hundred or more posts, I may pick up a bunch of it, but I'd rather speed up progress! Can you please list some abbreviations you guys use here and what they mean? Also, If you have questions on what a certain abbreviation means, this is a good place to ask! What does p/c mean? I'm thinking piston/cylinder, but not sure. StihlRockin'
