The cover is made out of rubbery plastic, I just split the inside loop of it so that it will clip onto the plug wire boot. That done, I worked the saw for awhile today cutting some smaller branches that fell down in a storm last week. The 194 cuts and oils quite well, as good as a stock 31cc saw can. The exhaust sound has a nice snort to it also. The only gripe I have is the loose feeling of the spring AV mounts, I like the rubber ones of my Echo saws alot better. Otherwise, the 194C is a fun little saw to run!
