What are the reasons for decreased car power?
1 Answers
The reasons for decreased car power are: 1. Clogged fuel tank vent hole; 2. Partial blockage of fuel tank switch, fuel filter, or fuel line between tank and carburetor; 3. Incorrect ignition timing causing premature combustion and detonation of fuel-air mixture; 4. Malfunction in ignition system; 5. Severe cylinder wear increasing clearance between piston, piston rings and cylinder, reducing sealing and causing cylinder head leakage, which lowers compression pressure; 6. Excessive carbon buildup in engine and poor heat dissipation; 7. Too much or too little lubricating oil in crankcase, deteriorated or contaminated oil, or clogged oil passages affecting engine power.
