Compression is low, even for a compression release on cam. Plus it is a 24 year old engine. It may be over for this engine.

Check the belt tension by pressing on the belt with your fingers at the longest point in between spindles. Unfortunately, without experience, it is difficult to determine good belt tension.

If you can adjust both sets of valves in 10 minutes, you should start your own shop. Labor book times allows 45 minutes per cylinder.

Thank you for bringing up the point of different switches. There are 5, 6, and 7 post ignition switches for mowers, etc. Matching up the numbers of post doesn’t always work. I wish I had known this in the past.

You can shorten the spring to get better tension if needed and form a small loop on cut end.

Dirt/debris/oil buildup on cooling fins and engine will overheat the engine and blow head gasket, push valve guides, etc. if it gets bad enough over time. These are air cooled engines, and the cooling fins are essentially like the radiator for a vehicle.

The distance from the cutting edge of blade to the flat, level concrete (with air pressure in tires adjusted properly), is the actual cutting height. Without measuring it, you are only guessing. If it is actually at 2.25”, I would leave well enough alone, when the dial is at 2.25”. The real...

The dealer already threw three parts at this mower. I don’t know that I would rush back to this same shop again.

Clean OEM carburetor always before replacing with an aftermarket carburetor.

NO!

Trying to do this from a hole in the engine block, and then sealing the hole, and then this Tecumseh engine actually running right is a long shot. Piston. rings, and cylinder are probably scored and engine is worn out. Either age, run at too high of RPM, or low engine oil caused it to break the...

Think twice about installing a mulching kit. Time consuming to get on and off, and mulching is never better than letting the grass fly out of the discharge opening. Get a discharge flap for the short time you are mulching leaves in the late fall.

With belt removed from spindle or pulley, spin it. Does it sound rough, or keep spinning longer than it should? Grab the pulley or spindle pulley and rock it back and forth with your hands. Does it have play, or feel nice and tight? On spindle you can also grab the blade and check for play in...

Why not replace the push rods, adjust the valves, and send it back to customer first? I have never seen a twin cylinder engine that bent both intake push rods, but removing cylinder heads and replacing is expensive. Repowering the engine would be a last resort.

Don’t get caught up in how much oil an engine is supposed to have according to the manual. Add oil until it is full. Honda and Kawasaki you do not screw in the dipstick. Check your oil on a consistent basis. Change your oil every 50 hours or once a year. And yes, many air cooled small engines do...
