2. PERFORMANCE 2-1 MAXIMUM OUTPUT The maximum output is the output of an engine with its throttle valve fully opened under the condition that all the moving parts are properly broken in after the initial break-in period. A new engine may not produce full maximum output while its moving parts are still not broken-in. NOTE : Power curves shown in the[...]

8. CARBURETOR 8-1 OPERATION AND CONSTRUCTION 8-1 -1 FLOAT SYSTEM The float chamber is located below the carbure- tor body and, with a float and a needle valve, maintains a constant fuel level during engine op- eration. The fuel flows from the fuel tank into the float chamber through needle valve. When the fuel rises to a specific level, the float r[...]

8-1-2 PILOT SYSTEM n The pilot system feeds the fuel to the engine during idling and low-speed operation. The fuel is fed through the main jet to the pilot jet, where it is metered, and mixed with the air metered by the pilot air jet. The fuel-air mixture is fed to the engine through the pilot outlet and the by-pass. At idling speed, the fuel is ma[...]

The following three conditions must be fulfilled for satisfactory engine start. 1. The cylinder filled with a proper fuel-air mixture. 2. Good compression in the cylinder. 3. Good spark, properly timed, to ignite the mixture. The engine cannot be started unless these three conditions are met. There are also other factors which make engine start dif[...]

(4) Incorrect Valve clearance If the correct compression is not obtained even after remedying the above, disassemble the engine and check further as follows : a) Valve stuck open due to carbon or gum on the valve stem. b) If the piston rings are stuck on the piston, remove the piston and connecting rod from the.engine. Clean or replace the parts. 1[...]
