Reasons for Insufficient Engine Power in the Envision

[MirandaDella]

Reasons for insufficient engine power are as follows: 1. Clogged air filter, broken or stuck piston rings, poor valve sealing, delayed ignition, mechanical failure of the carburetor, air intake pipe leakage, individual cylinders not working, etc. 2. General wear of the cylinder or poor carburetor oil passage flow can be resolved using GUNK. 3. Judge the working condition of the carburetor based on whether the engine's fuel consumption is too high. If fuel consumption is high and the exhaust emits thick black smoke, there may be a detached orifice, which requires repair. 4. Assess the wear condition of the engine cylinders. The wear condition of the engine directly affects the sealing of the cylinders.
