Many models of Troy-Bilt string trimmers make use of the SpeedSpool trimmer head. The SpeedSpool accepts cut lengths of cord that you end onto the spool from hand or the insertion of a spool that’s already filled with the proper dimensions and length of trimmer line. Before buying a SpeedSpool to your older model Troy-Bilt trimmer, do your own homework to discover whether or not it is one that can use the SpeedSpool. SpeedSpool Basics The characteristic of the SpeedSpool that makes it so appealing is that you can install new individual lengths of trimmer cord without removing the bump head or the spool. The SpeedSpool will manage two 10-foot lengths of trimmer line. Always use 0.080-inch replacement line. Other sizes of trimmer line might not feed properly and might feed too fast, too slowly or even not at all. Troy-Bilt also says you shouldn’t use metal-reinforced trimmer line in…

The carburetor on a two-cycle motor, like the motor on a Craftsman chainsaw, regulates the quantity of fuel that enters the combustion chamber. This is an important function, because the wrong combination of air and gasoline creates incomplete combustion and poor engine operation. The adjustment process isn’t complex, but you want to get a tachometer, or even a relatively straightforward job can become a frustrating and potentially damaging one. Carburetor Adjustment Screws The carburetor on a Craftsman saw is comparable to the one on most two-cycle engines since it has three adjustment screws. Among those screws, which is arranged at the apex of a triangle, adjusts the idle speed whereas another two regulate the total amount of fuel that the carburetor sprays once you depress the throttle trigger. The low-speed screw sets the fuel ratio for low-speed performance while the high speed screw sets the ratio for maximum motor speed….

Sometimes you see large, concealed objects like stumps and rocks at the last moment, which makes it hard to avoid hitting them while you mow your lawn. This not only damages the cutting blade, but can also split the engine crankshaft and other internal components. A broken engine crankshaft is an expensive fix, and it takes basic hand tools and a couple of specialty tools to replace. You have to consult with the lawn mower service repair manual for a reference manual for torque specifications. Drain extra fuel in the fuel tank of an engine that has the fuel tank mounted on the engine assembly. Unhook the engine throttle cable’s Z-shaped finish in the carburetor throttle linkage using needle-nose pliers. Remove the retaining screw, and raise the air filter assembly away in the carburetor. Unhook any wire connectors that may be running to the engine on riding mower models. Unscrew…
