FitBest Accessories Editorial Review

The FitBest Big Bore Cylinder Head 49mm Piston Kits Assembly has received mixed reviews. One customer reported that the product did not work on their MS 311 chainsaw, while another stated that it worked well on their 290 chainsaw and got it running again. One customer with an engineering degree found the product to be a straightforward fix for their 029 chainsaw, but noted that there was no picture of the top of the head/sleeve, which required an additional purchase of a decompression valve port. They used lithium grease spray to compress the ring while assembling the head onto the piston, as they found that using a tool did not work. Overall, customer experience with this product has been mixed.
