It is one of two problems - your engine uses a cam with a plastic gear - this gear has a tendency to move - it will probably need replacement . there is also a chance that the valve seat is coming loose (overhead valve ) which keeps the valve open - check the distance of the valve stems to make sure they are both out the same distance if they are not then when you put a new pushrod in and adjust it the valve will be pushed too far and hit the piston in turn bending the pushrod

    almost forgot ; theres a chance that the valve guide itself has moved outwards bottoming out the valve - make sure both sides are extended both the same amount

I HAVE A 24 HORSE Poulan riding lawnmower pro that keeps bending the rods and it has no power. I was wondering if this could be a timing problem.

It a design problem. Where you adjust valves it happen. You need correct valve adjusted, check valve seats they can move. I've had mine 17 years. One problem, adjusted one valve to tighen. Bent a pushrod

What would cause both pushrods on left cylinder to bend

One ting that cause a push rod to bend is a valve guide that work it way out causing bottoming the spring travel. I haven't seen this person but work with others on finding the problem.

It is strange that both bent would be bent; although a valve that broken free could this too. Since OHV valve guides are generally not available as a replacement part the only solution is to replace the head.

14 hp kawasaki wont start but backfires through the carberator.

The timing chain has slipped a few link and is out of sync. This happens with a loose chain. Replace chain and re- align with the timing marks

Battery will not take charge, but can jump start and it runs, but does not keep charge

Possible charging coil under the flywheel issue, or with the retifier, there is a tool called a negative shunt, this will quickly tell you if there is any charge to the battary from the engine

Does the spring loaded screw on the carburetor bowl on the 15hp liquid cooled engine adjust the float level?

No. A metal float is adjusted by slightly bending the small metal tangs on the float that hold the retaining pin as it hangs from the main carburetor body . If you feel the need to adjust the level of the float, your normal setting is with the float "level" in relation to the lower carburetor body. That is in it's raised position when it has sealed the fuel inlet by pushing the float needle all the way into it's seat; thus shutting off fuel flow into the bowl.

Engine runs fine til hot.

I think one of the intake valves, or a valve pushrod, is bent or warped. When the engine heats up, the metal expands and the valve starts sticking open. That would cause compression to be lost in one cylinder, reducing available power so things drag when you engage the blades. This would also causes air/fuel to be blown back through the intake. I think you'll need to take it to a small engine mechanic. Good luck! Please rate my solution if helpful, thanks.

My lawn mower will not start, it has spark but 0 compression.

A bent or broken pushrod is just a symptom of a larger problem that is causing a valve to hit the piston (or vice versa). Since you say the valves open and close, it's probably not a bent valve shaft, and like you suggest, it's the valve timing which is controlled by the camshaft gear. No matter what, it's not a repair to tackle at home. If the mower's in warranty, take it back for a proper repair -- and consider trying a different shop than last time. If it's out of warranty, you might find a small engine mechanic that can fix it for less than the price of a new motor. Get a good estimate before you say yes.

Backfire - Husqvarna YTH20K46

I find my 2148 runs much happier on the medium grade shell than on the cheaper gas. I did have a nasty POW, which resulted in bent pushrods, or perhaps the bent pushrods caused the POW. After replacing the pushrods, and adjusting same, the backfiring stopped altogether. knock on wood. The 21 is a B&S engine which has a propensity to the bent pushrods. Fortunately for me, my neighbor is a wiz at those fine adjustments.

Blowing fuses

try unplugging the pto, starting the mower and then engaging the blades. If it still blows a fuse the problem lies in the mowers wiring. If not the problem is the pto. Hope this helps
