The compression ratio for an 8 hp Tecumseh motor typically ranges from 7:1 to 8:1. This ratio refers to the volume of the cylinder when the piston is at the bottom of its stroke compared to when it is at the top. It's important to reference the specific model, as variations may exist. For precise specifications, checking the manufacturer's manual is recommended.
The top two rings are both compression rings and the third is the oil control ring set, Nominal is 0.010" and minimum is 0.006" with 0.014 for the oild ring set.
HM80 stands for horizontal medium-frame 8 HP and HMSK80 stands for horizontal medium-frame Snow King(in other word a snowthrower engine) generally equipped with a looped starter grip for mittened hands, intake system that resists icing and possibly an electric starter that uses household current.
The Tecumseh HM80 engine has a displacement of approximately 8 horsepower and is typically around 318 cubic centimeters (cc), or about 19.4 cubic inches. This engine is commonly used in various outdoor power equipment, including lawn mowers and snow blowers. Its design focuses on providing reliable performance for small to medium-sized tasks.
Well 1 horsepower is about 750 watts so 6000 watts is 8 horsepower. If you had 8 horsepower running to each of the four wheels ( 24,000 watts ) in direct drive with no efficiency loss do to transmission gearing and removed the engine and transmission then you be able to drive a light weight body like a geo metro. Also the type of engine you are using would be important for a car you should really look at 3 phase ac induction so you would be able to climb hills. Car hub motors are starting to enter the market they have the motor inside the rim and I have been seeing those at 8 hp at 899+. 1 company actually makes 160 hp hub motors for cars. but those cost 10k + each
While there are some 8 cylinder engines that have been made in the past that are inline, it is mostly prohibitave because of the length of the engine. Its too long to fit in most cars. Hence the V8, or straight 6. Also the straight 8 motor design is a balanced design that does not create bad harmonics at high rpms, and has what we call "inherent primary, and secondary balance" Some examples of a straight 8 are 1940's Oldsmobile engines, some prewar packards, airships, airplanes, boats. All sorts of things, but they were phased out after WWII for vehicles mostly.
The compression ratio of a Tecumseh 5 HP engine typically ranges from 8:1 to 10:1, depending on the specific model and application. Compression refers to the reduction of the air-fuel mixture in the engine's cylinder before ignition, which is crucial for efficient combustion and power generation. Higher compression ratios generally enhance engine performance and fuel efficiency but may require higher-octane fuel to prevent knocking. It's important to check the engine specifications for the exact compression ratio of your specific Tecumseh model.

The correct spark plug for a 5 hp. Tecumsen 4-cycle motor is Champion J-8 (RJ17LM). The plug gap is 0.030 in. (0.76 mm)
The compression rating for a 1988 8 HP outboard motor typically ranges from 90 to 120 psi, depending on the specific model and condition of the engine. It's important to check the manufacturer's specifications for the exact rating and to ensure the engine is properly maintained for optimal performance. Low compression can indicate engine wear or mechanical issues that may need to be addressed.

On your motor mount
Use a Champion RJ19LM set to a 0.030" gap.
The correct oil capacity for an 8 hp Tecumseh engine typically ranges from 20 to 24 ounces, depending on the specific model. It’s important to check the engine’s manual for precise specifications, as variations can exist between different models. Always ensure the engine is on level ground when checking or adding oil.

I have at 1990's TRS 27 snowblower- It's an 8 HP Tecumseh
It depends on the horse-power of the engine. 220 cc would be about 8-10 HP, equivalent to a 6-8 HP electric motor. But a small petrol engine is usually not used at full power continuously, so manybe a 5 HP motor would do the job.
