Lawn mower follies....

Post by TwinStick » Tue Aug 01, 2017 9:35 pm

So, got a Craftsman 3-in-one push mower. Have had it for about 10yrs. Been having trouble with it off & on for the last 2 seasons.Took the carb off 2x each of the last 2 yrs & cleaned it real good. Good for a while, then more issues. Took the gas tank off & hosed it out real good. Good for a while, then more issues. Replaced spark plug, good for a while, then more issues. So, today I was ready to shoot the SOB. Get on the interweb & find out that it is a common issue. So, tomorrow morning, I'm gonna go looking for a new coil & hope to put this issue to bed once & for all. Issue: Starts fine. Runs fine. Runs better with the E-3 plug i just put in it. Stop to empty the bag & it is just hit or miss, if it will start up again. Kid lost the OEM gas cap a long time ago. Only one i could find to fit it, had no vent. Thinking vapor lock may be the issue, i drilled a tiny hole in it today & it started right back up. Thought maybe i had it ? Nope, next bag full, it would not start. Hoping it is the coil. What a PITA. Just does not like to start when hot.

The problem is the "operator presence cable" stretches or begins to seize in the cable housing and doesn't fully release the kill switch. They might also call it a "zone control cable". It's the cable that runs from the bail handle down to the flywheel brake. It happens slowly over time and you don't notice it, but the bail handle gets harder to pull down. Check it before you go buying a new coil. There's a small wire that runs from the kill switch over to the coil.
If it's a Briggs & Stratton engine, hang on to it. They don't make um' like they used to. The newer engines are a POS Chinese Honda knock-off. :angry:
Good luck! :patriot:

Well, I replaced that cable just last year, so i ruled that out. Maybe it is f***ed again, IDK ? It seems to be working fine ? Coil did not help. About the only thing else I can think of, is that little wire that runs from the coil, to the kill switch. Maybe there is a crack in the wire & the heat makes it worse ? I will look into that next & probably just make up a new wire-to be sure. Today, Our new A/C system is being installed. Cant wait.

When my bail handle cable frayed and got stuck in the sleeve I just tore it all out and connected a toggle switch to ground out the contact to kill the engine.

So today, I made up a new piece of wire & crimped a new connector on the end. So far, so good. It has started every time, even after letting it run for awhile. Maybe the wire was cracked, IDK ? It was a solid piece of wire, no strands. The one I replaced it with was a 10 Ga wire w/strands. Cleaned up all the contacts real good & zip tied the on/off cable to the handle in 6 places, so now the cable moves farther, instead of the cable and housing moving. Just in case, I drilled a tiny hole in the air filter cover, so I can shoot some starting fluid in there if it wants to play games again. We'll see. Been storming all day. Spent the afternoon putting foil tape on all the places that were leaking air on the new a/c system.

Well, that didn't last long. Lawn mower got much worse. Saturday it finally quit running all together. Would not start, not even with starting fluid. So I took it all apart for about the 25th time & think I finally got it this time. It was a 2 fold problem. There was 1 stray strand of copper wire, where the coil attaches to the operator control mechanism, that touched the metal shroud that holds the pull start. It barely touched it. So, I cut that off & cleaned it up again. The carb kept dumping gas & leaking all over. Took carb apart again & cleaned it real good again. Put it back together & same thing. Bought a carb float rebuild kit. The problem: ethanol. It shrunk the tiny minuscule rubber seat for the float needle valve & it was getting jammed in there sideways. Replaced it, filled with gas & it started up first pull. Mower the whole lawn, stopping 4x to empty the bag & it restarted each time with 1 pull & no primer. :rockon:
