Question about Honda GCV160 Engine
I stripped the carb down following fuel in filter and exhaust and checked the float in the float bowl. I have now reassembled it and am unable to deploy the cord. It is very stiff. I was initially able to move the blade slightly but now nothing is working.Is this due to fuel in the cylinders? When I took the spark plug out there was fuel everywhere. If it is how do I get the fuel out?
You are absolutely right on target. This is called 'hydro-locking, In fact many engines have been destroyed when a leaking fuel injector ,overnight, even partially fills a cylinder that is on compression stroke. With the higher cranking speeds today, It usually bends the connecting rod when the engine rotates 1/4 revolution s or more and 'hits' the in-compressible liquid.
In your case, simply remove the spark plug, and pull the rope a few times to blow out the gasoline and then add a teaspoon of oil in the cylinder, pull the rope a few times to re-lubricate the cylinder. When there is no liquid coming out, reinstall the spark plug and it should be good to go.
With carburetors, even a tiny speck of leaf or grass can cause the float valve to leak.

Sounds like you got a huge amount of fuel in the cylinder. I'd tilt the engine up with spark plug hole open and down. Leave open overnight. Next you Must change the oil. Fuel is in the oil and may destroy the engine. You have probably "washed" all the oil off the cylinder so it is difficult to move. Leave the drain open overnight.

The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.
Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.
Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.
Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.
