1. Restricted fuel tank vent system. 2. Loose float bowl screws- When your carburetors bowl screws are loosed it allows fuel to drop from the port, sometimes it could be due to a worn out bolt or threading in carburetor. 3. Damaged float bowl O-ring- a damaged rubber seal/o-ring could also cause fuel leakage, since it can't seal the space no longer 4. Damaged or leaking float assembly- a float assembly include the jet and the float. Dismantle the float assembly and make sure that the fuel inlet is not blocked 5. Particle contamination in fuel inlet fitting cavity-using a carburetor cleaner; soak carburetor in it for at least 30 minutes then couple.. 6. Worn or dirty inlet valve or seat- bad valves and seats could also cause this, in two stroke generators(small gen), the carburetor seats directly on the valve. You can loosen the valve at the back of the valve, therer ar two screws loosen them clean valve wit petrol them couple back and tighten the carb 7. Improper fuel leve

Valves controls the flow of fuel vapour in the combustion chamber and the flow of exhaust gasses leaving the engine. faulty or dirty valves may stick & can develop pits, cracks, & grooves that can cause the engine to loose power and fuel efficiency. if you are having problems with your engine or you just want to do an overall valve maintainance, go with the steps below.. HOW TO REMOVE SMALL ENGINES VALVES FOR INSPECTION in order to properly inspect your valve, you have to remove them....  NOTE: wear saftey eye wears when removing your valve... STEP 1: remove the spark plug and secure the spark plug lead away from the spark plug. STEP 2: remove air cleaner assembly, fuel tank , oil fill tube, blower housing, carburetor and any other engine parts that blocks access to the cylinder head  STEP 3: remove muffler/exhaust from the cylinder, cranck case breather and any other that blocks access to valve chamber STEP 4: open cylinder cover   ,remove rocker arms fr

Replacing your generator's air filter is one of the most important and easiest things you can do to extend the life of your small engine. having a dirty air filter could cause lack of air of a Essentially, if your small engine air filter is clogged, your generator can't breathe, and that can cause poor engine performance. The 3 main types of small engine air filters arepleated paper,foam, anddual element air filters. A particulate air filteris a device composed of fibrousmaterials which removes solid particulatessuch as dust, pollen, mould, and bacteria from the air. A chemical air filter consists of an absorbentor catalystfor the removal of airborne molecular contaminants such as volatile organic compoundsor ozone. Air filters are used in applications where air quality is important, notably in building ventilationsystems and in engines. How to Change an Air Filter 1. Loosen cover screw. 2. Tilt cover down. 3. Carefully remove air filter 4. Install new air filter 5. Clos

Exhaust port is a passage through which the burnt mixture is passed out from the combustion chamber. it is located differently in different engine cyles. In a two stroke generator it is underneath the engine block while in a four stroke generator it is located on the left hand part of the cylinder. The exhaust muffler is connected to the port to reduce the sound from the generator and also to expel the harmful gas coming out from the engine. Mostly in two stroke engines; carbon usually piles up both at the exhaust port and inside the muffler thereby causing low RPM. In power generators this brings about low current. Removing carbon deposits is easy with this easy to follow steps: 1) loosen the exhaust from the exhaust port 2) get a long screw driver and drive it into the exhaust port, clean all carbon deposits from the port 3) use the screw driver to also clean the muffler through the hole..i usually pour in a little fuel in my muffler and light it up so it could dry up the carbon

A piston ring is a split ring that fits into a groove on the outer diameter of a piston in a reciprocating engine such as an internal combustion engine or steam engine. The three main functions of piston rings in reciprocating engines are : 1.Sealing the combustion chamber so that there is minimal loss of gases to the crank case. 2.Improving heat transfer from the piston to the cylinderwall. 3.Regulating engine oil consumption by scraping oil from the cylinder walls back to the sump. The gap in the piston ring compresses to a few thousandths of an inch when inside the cylinder bore... If the piston and rings is bad/ worn out it could cause serious damage to the engine HOW TO KNOW WHEN YOUR PISTON AND RINGS ARE BAD. When Engine oil passes the cylinder wall and gets to the combustion chambers, it burns and the exhaust brings out white smoke.. 2)when the engine is stuck(also known as knocking) due to lack of oil in the rings grooves..

A gasket is a mechanical sealwhich fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow"less-than-perfect"mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials. Gaskets are normally made from a flat material, a sheet such as paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, polytetrafluoroethylene(otherwise known as PTFE or Teflon) or a plastic polymer(such as polychlorotrifluoroethylene).. Let's talk more on the cylinder head gasket. If the gasket is bad in an engine for instance you'll notice air leaking out from the cylinder when you draw the engine. To confirm, Pour little fuel ontop of where the cylinder is connected to the block and start, you'll notice bubbles.This is a major cause of HARD STARTING, loosen the cylinder bolts and change gasket..i c

How does aCrankshaftwork in a small engine? The crankshaft attaches to a piston by a connecting rod. During each cycle, the crankshaft rotates to push the piston up in the cylinder. Crankshafts rarely break, but if they do, it can cause serious engine damage. If you're doing an engine overhaul, don't forget to replace the crankshaft. Acrankshaft—related to crank—is a mechanical part able to perform a conversion between reciprocating motionand rotational motion. In a reciprocating engine, it translates reciprocating motionof the pistoninto rotational motion; whereas in a reciprocating compressor, it converts the rotational motion into reciprocating motion. In order to do the conversion between two motions, the crankshaft has "crank throws" or " crankpins", additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rodsfrom each cylinder attach. It is typically connected to a flywheelto reduc

At this point i'm assuming we know what a two stroke engine is and how it works. If not check out my previous post on DIFFERENTIATING A FOUR STROKE ENGINE FROM A TWO STROK ENGINE I'm also assuming that you've comfirmed that what's causing your generator to produce low current or fire low is not the coil/capacitor Carbon residue could block the exhaust passage thereby stopping carbonmonoxide from leaving the combustion chamber. "DECARBONIZING_YOUR_ENGINE" Now we'll be looking at how you can clean out those carbon residue from your two stroke engine. 1)loosen the four bolt holding the tank, remove fuel hose connecting tank to carburetor then remove the tank 2)loose the cylinder cover so you could get to the cylinder. 3)loosen two nuts and two bolts holding cylinder to engine block, remove gasket also then soak in gasoline for 10mins to help soften the carbons on the cylinder's head. 4)loosen exhaust bolts from under the engine block..
