Import interference engines include the following:

* Virtually all Acura and Honda 4-cylinder and V6 passenger car engines;
* 1994 and newer Audi 2.8L V6;
* 1998 & up Audi 1.8L;
* All BMW 2.5L and 2.7L 6-cylinder;
* All Hyundai 4-cylinder and V6 engines;
* Infiniti 3.0L V6;
* Isuzu 1.5L, 2.0L, 2.3L & 2.6L engines;
* Kia 2.0L in the Sportage,
* Mazda 2.0L in the MX-6 and 626, and the 3.0L V6 in the 929 and MPV;
* Most Mitsubishi engines, except the 1.8L, SOHC 2.0L 4-cylinder & SOHC 3.0L V6;
* All Nissan 4-cylinder and V6 engines;
* All Porsche engines;
* 1989-'94 Suzuki 1.3L DOHC;
* Toyota 1.5L Tercel engine;
* 1990-'92 Volkswagen 1.6L diesel; and
* Volvo 2.3L and 2.4L engines.
Unfortunately, the owners of many of these vehicles are totally unaware that their timing belt needs to be periodically replaced for preventive maintenance. The belt is out-of-sight and out-of-mind and, unless they read their owner's manual (which few ever do) and see the replacement recommendation in black-and-white, they usually ignore the belt until it's too late.

You found 'it' and it should point UP.

When testing engine compression it builds up when the engine is turning over and when you stop turning it over the compression tester has a valve in it to hold the pressure reading I think your tester is defective and not holding the pressure reading

Most weedwackers are 2 cycle (stroke) engines, meaning the gas and oil are mixed together before you pour it into the gas tank. If it's a 4 cycle engine it appears there is no dip stick or convenience way to check the oil, you can only replace it. Here's a youtube video that may help.

Remove auxiliary drive belts, water pump pulley, crankshaft pulley, timing belt upper cover, timing belt lower cover. Turn crankshaft clockwise to TDC on No. 1 cylinder, slacken tensioner bolts 5 & 6. Move tensioner away from belt and lightly tighten bolts. Remove timing belt. Remove water pump and replace with new one. Suggest to replace cambelt as well.

check crack sensor

check fuel pressure with a gauge,turn the key in the on position an read pressure ,if pressure goes lets say to 40 or 50 on one key cycle pump is prob. good . if it takes 3 to 4 key cycles to achieve this pressure ,pump is bad or connection in tank is bleeding off over night.
