3. Clean cylinder fins (A) to allow cooling air to pass freely. 4. Replace cover and tighten screws. 5. Connect spark plug lead. A EXHAUST SYSTEM Spark Arrestor Screen Level 2. Tools required: Cross Head Screwdriver Parts Required: Spark arrestor screen P/N 14586206720, Gasket P/N V104000220 IMPORTANT Carbon deposits in muffler will cause a drop in engine output and overheating. Spark arrestor screen must be checked periodically. 1. Remove spark plug and engine cover (five screws). 2. Remove spark arrestor cover (A), gasket (B) and spark arrestor screen (C) from muffler. Replace screen if plugged with carbon deposits. 3. Install spark arrestor screen, gaskets, and cover. 4. Install spark plug and engine cover. Cylinder Exhaust Port Level 3. AB C IMPORTANT The cylinder exhaust port must be inspected and cleaned of excess carbon every 3 months or 90 hours of operation in order to maintain this engine within the emissions durability period. ECHO strongly recommends that you return your unit to your ECHO dealer for this important maintenance service. 22 22 Engine Break-In New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required. High Altitude Adjustment High altitude adjustment is not required for proper operation of this engine. Level 2. Tools required: Screwdriver, tachometer (Echo P/N 99051130017) Parts required: None. NOTE Do not adjust carburetor unless necessary. If you have difficulty, see your ECHO dealer. Adjustment Screws Idle Speed (A) Controls throttle opening at idle. Low (LO) Speed (B) Controls amount of fuel at low speed and supplementary fuel for smooth progression from idle to high speed. High (HI) Speed (C) Controls amount of fuel at full throttle Before Adjustment Check that: • Air filter is clean and properly installed. • Spark arrestor screen and muffler are free of carbon. • Blower pipes are installed. A C B POWER BLOWER OPERATOR'S MANUAL POWER BLOWER OPERATOR'S MANUAL 1. With engine off, turn HI speed screw (C) counterclockwise to stop. 2. Turn LO speed screw (B) midway between stops. 3. Turn idle screw (A) until tip of screw just touches throttle plate; then turn three (3) turns clockwise. Final Adjustment IMPORTANT Limiter caps prevent exceeding emission limits and over rich adjustment, but not over lean adjustment, which can cause engine failure: Do not exceed recommended HI speed engine R.P.M. during operation, or for long periods during adjustment. 1. Start engine, run at idle for one minute. 2. Complete warm up by running at full throttle for 5 minutes, operating choke twice to clear air from carburetor chambers. 3. Run at idle and accelerate to check for smooth transition from idle to high speed; if engine hesitates, turn LO speed screw (B) counterclockwise 1/8th of a turn at a time until acceleration is smooth. 4. Use a tachometer to adjust idle speed to specifications found on page 9.
