If brushes need replacement, remove by unhooking the terminals or cutting the connections and then resoldering. Install the spring cover and the cover screws. Move the punch around while driving the pin to help keep the pin straight. Continuity should exist between these two points. Yellow Green Green Yellow Yellow A. Rotate the control lever toward the idle position until continuity is obtained.
The idle mixture screw is located on the top of the carburetor near the engine. Turn the pulley counterclockwise to fully wind the starter return spring until tight. Replace both reeds If either is defective. Loosen the two bolts holding down the stator and rotate the stator until the continuity light or Ohmmeter indicates a break in the circuit. This causes a generation of current flow in the coils primary winding. Apply a small amount of lithium grease to the inner bore of the center shaft.
Tighten the stop bracket to secure the stator. Untie the temporary knot and allow the rope to recoil. Tecumseh 2-cycle engines are lubricated by a gas oil mix. Set float to proper level. Then an additional 1 turn for a static setting. Reopen fuel shutoff for normal fuel flow immediately after engine starts.
To assist you in making repairs, we have developed the quick reference illustrations below. Before going into extensive checks, be sure to examine the more basic causes first, such as: 1. If the coil is located under the flywheel, no other timing is required. Install the float bowl by placing the detent portion opposite of the hinge pin. When removing air cleaner body from carburetor, remove plug in the body to gain access to the mounting screw.
Check timing, point gap, and if necessary, overhaul magneto. Use the small tip for engines with timing dimensions of between Top Dead Center and. The Torsion Spring supplies the pressure to the brake lever and brake pad to stop the flywheel. The absence of adjustment screws indicate fixed jets with no adjustments necessary. This will be the optimum carburetor setting. Seal driver-protectors are available for most one piece oil seals.
This official service repair manual gives complete step by step information on repair, servicing and preventative maintenance. Clean, and if necessary repair governor parts. Increased crankcase pressure closes the valve, preventing escape of the fuel-air and oil mixture back through the carburetor. Always consult the Tecumseh Master Parts Manual for the correct replacement parts. Install dog spring and dog in starter pulley in the socket closest to the rope hole in pulley. Use of the blade brake clutch in conjunction with either a top or side mounted recoil starter. Be careful not to damage other parts.
Pinch the legs of the retainer together and pull on the head of the retainer to remove it from the housing. Tighten the lock screw to hold the cam in place. Changes in the engine R. These recoils are used on all small and medium frame series engines. Tighten the screw then recheck the gap. If there is no designation, the sequence is gasket, diaphragm and cover.
Spark Plug Gap Piston Ring End Gap Piston Diameter Top Piston Ring Groove Width Bot. In order to restart the engine, the brake control must be applied. To put tension on spring, wind pulley counterclockwise until tight, then allow to unwind until the hole in the pulley lines up with the eyelet in housing, then install rope and handle. Install the return spring if necessary. Using a continuity light or ohmmeter, check the field by attaching one lead to each field coil connection. Check magneto wiring for shorts or grounds; repair if necessary. Install a new recoil spring if necessary by pushing the new spring out of the holder into the pulley cavity while aligning the outside spring hook into the deep notch in the pulley.
Check to see that it is the correct screw. M drop, the air velocity also drops, allowing the governor spring to pull open the throttle shaft and increase engine speed. If 2 Stroke, make sure air vane is not binding, proper assembly or linkages and linkages are not bent. Check seal for fuel drain or bowl gasket. If throttle plate has only one line, the line should be positioned in the 12 oclock position. These serviceable air cleaners utilize a polyurethane element which will clog up with use.
