Thread: how long can I limp along a low compression engine?

Tweet

With two low cylinders, and not next to each other, would probably drive it 'as-is' for a while, take anothe comp. test. You might find that a valve was not seating well (carbon) or a top ring or two were also gummed up (also carbon/rust/crud)

my guess would be running fat for a long time , very little use , cylinders most likely washed down. get it tuned and put some hwy miles on it. like said it will likely run forever.

Installed new manifold, carburetor, MSD ignition and coil, new plug wires, replaced fuel pump and battery. Engine will start and run at higher rpms but stall out and die.
