If you order a new aftermarket carb off sawzilla they made me a offer recently when completing my purchase to add their solo tachometer to the order for under 30 bucks. I own a solo tac and it has worked great for setting carbs up on saws, mowers, generators, 4 wheelers, blowers etc
I have experienced very few problems with their parts over the years when oem is nla, and they have a few rapid shipping options. When dealing with carbs on saws I replace the fuel pickup hose, impulse hose and fuel filter at the same time, the hoses loose their grip/stretch, their rigidity/strength and if disturbed can cause further gremlins and a tune up never hurts.
