Have you tried checking the needle and seat in the carb. Sounds like it may be sticking closed. Best way to check this is to remove float bowl and move the float up and down by hand. if needle moves then it should be ok if not try pulling it out of main jet and blow air into it.
suction filter
The compression ratio is simply the ratio of the absolute stage discharge pressure to the absolute stage suction pressure.
At very low suction pressure, the suction valves of reciprocating compressor will not work and there will be no gas in the cylinder during compression stroke, resulting some damage to the suction valves. If low suction pressure trip protection is not provided there can be some abnormal damage.

1. PRIMING LOSS: This is the suction loss for a pump whose NPSH is (-ve)2. CAVITATION: It is also suction loss by forming cavity of a volatile liquid whose NPSH(a) is belowNPSH(r) eg..Choking or blockage of suction strainers, closing of suction valve of apump when running.3. VAPOUR LOCK: This is also loss of pumping due to blockage in discharge of a pump..closing of discharge valve and running for more time..running the pump with in adequate minimum flow..liquid above boiling pointHence Cavitation, Vapour Lock and Primimng loss are different
A blockage in the downstream side of the pump could make this pump work harder raising the amps as the pump now has to do more work to get through the line. An upstream blockage would make the pump spin more freely lowering the amps on the pump as it will not be doing any work.
IT COULD THAT YOUR SYSTEM IS EITHER OVERCHARGED OR UNDER CHARGED. ALSO CHECK YOUR FURNACE FILTER.AND MAKE SURE YOUR OUTDOOR UNIT is clear of dirt and obstructions. --------------------------------------------------------------- There are several reasons for a compressor to overheating High compression ratios are the result of either lower than normal suction pressures or higher than normal discharge pressures. Changes in suction pressure will affect the compression ratio more rapidly than changes in the discharge pressure. For this reason, it is important to keep the suction pressure at its highest possible value. Causes of low suction pressure can include incorrect sizing of components, misadjusted or defective metering devices (TXVs), loss of refrigerant charge, plugged driers or strainers, and excessive suction line pressure drop. Although not as sensitive to change as the suction pressure, the discharge pressure can still greatly affect the compression ratio. Keeping the discharge pressure within normal operating conditions is still important. Causes of high discharge pressure can include dirty condensing coils, undersized discharge line, a blockage or recirculation of condenser air, erratic condenser fan operation, refrigerant overcharge, noncondensibles in the system, and an undersized condenser.
there will be two cylinders... one will perform 1)suction, 2) compression, 3)power, 4)exhaustion... inbetween the another cylinder will perform only the suction and compression strokes..., so 4 + 2 = 6 Note: the two cylinders will be placed opposite to eachother with same centre axis.
A four stroke engine has four basic operations within the engine. It has Intake, compression, power and exhaust strokes. During the intake, or suction stroke, a mixture of fuel air is injected into the cylinder.
Pressure increases due to load(or heat intake from evaps).if asking about off cycle. If asking about compression cycle,its the compression of vapor into a higher pressure side of system along with heat of compression adding to temp-pressure relationship.
