Lawn Mower Engines Seem So Picky
wrote in message
oups.com... I do have a notoriously short fuse, I must admit. Today, a Tecumseh engine-based Ace Hardware self-propelled mower created a "that's the last straw" situation. It ran almost out of gas, and then when I put more gas in it (gas I purchased probably 30 days ago or so), it just flat-out wouldn't start. Some 20 minutes of priming with that bulb-thingie, sweat dripping off of me by the bucket-load, my allergies kicking in to such an extent that I developed asthma-like symptoms, all because I had a small patch to mow that wouldn't have taken me more than 3 minutes to mow. (I had just got an Intex easy-set pool and wanted to mow the designated spot once again to make sure it was "pool ready.") Some 20 minutes later, having added some gasoline and primped that thing numerous times, and it STILL wouldn't start. Oh sure it would sometimes "fake start" for maybe 1 second, only to then cut right off. It had been running just fine barely 5 minutes before all of this, but once it ran out of gas--forget it. I became so enraged, I took a large wood-log and smashed the lawn mower into a million pieces. OK, so that was childish, at least it was a $35 yard sale lawn mower (but it was self-propelled, making it something of a bargain). But man, 20 some minutes and it STILL wouldn't start, even with more gasoline added, even with it having ran just fine minutes previous? I am not just writing to vent and rant/rave, and hear people reply "wow, that temper of yours, how silly of you" (not that I blame anyone for saying that, I understand). I am writing for a reason, namely--are lawn mowers as a group this picky? Is there someway, without it requiring multiple servicing efforts at a repair shop, to make lawn mowers less picky? Are Tecumseh engines as a group worse than Briggs/Stratton engines? Any method of storage (outdoors, we don't have a garage) that helps with this? Any tricks that can "kick start" a stubborn-as-a-mule lawn mower into starting? Also, I do recall when I used to cut grass as a teenager some 20 years ago or so, it was common we'd run the lawn mower until it ran out of gas, then just add more and it would fire right back up and we'd carry on. It seems like now lawn mowers are much pickier--if you dare run out of gas, there's hell to pay. Is this true, and if so, why? Thanks for the tips. LRH Last year, got brand new push mower from Wal-Mart. 5 hp Briggs and Stratton. Worked fine the first few mows. Always used fresh gas. Then, it started doing exactly what you described. Run low on gas, stop and refill, won't start. However, was careful not to prime again to see if it would start like that. Then tried the prime button a couple of times, no luck. Long story, short. Found some crap in the tank and at the carb area. Spark plug said it was running rich, deposits. Air filter was very dirty from kicked up dirt as all was not grown over by grass yet. Cleaned all this up, changed the plug, and worked fine. My conclusion was that the dirt etc. in the fuel system was not a factor until low on gas with the engine stopped, then it showed its ugly face. Drained all residual gas from mower, after I ran it to the point of no gas late last winter, and stored. Changed oil and added gas. Fired up fine this spring. Dirt in air filter is not as much of problem this year, as bare areas are covered with greenery now. All current mowers are picky about the primer button, too much priming is guaranteed to flood the engine. Without aids, at that point, you have remove the plug and let it air out for at least a half an hour. Same memory here when young. Drove the heck out of Briggs and Stratton 3.5 hp push mower. Mowed alot of dusty areas too including a self-made ball field. The difference seems to be in the choke system and sensitivity to airborne dirt. A 20 lb sledge hammer is more appropriate for these newer "engineered freak" mower engines. But alas, we all don't have the same laboratory conditions that these "engineering marvels" were meant to operate in. -- Jonny |
