Thats right ,always run at full throttle
It's an EFI engine... There's no carburator adjustments that can be made. Plus, any engine made in the last 15 or so years has no adjustments on them anyway.
the dealer said that was going to be 3 hours in labor @ $78 an hour and the part is $2.75... ya the motor runs perfectly fine the only bad thing was that the muffler glowed at night, i only noticed it when i was getting ready to shut it off and it had been running at half throttle for 5-10 min... should i call them out of the 3hr of labor? and for the record i would do it myself but im busy with school and walkers are new to me also i didnt know what the problem was in the first place.
why do they think the flywheel key is sheared?
Sheared flywheel key symptoms:
The symptoms of a sheared flywheel key range widely from a barely noticeable misfire to a no-start condition. In between these extremes the engine may misfire noticeably, run rough, backfire, be difficult to restart hot, or lack power. Advanced timing can cause engine overheating. A muffler glowing cherry red probably indicates ******** timing. These variations depend on just how far the flywheel has spun out of time and in which direction. The key may have only partially sheared, or the flywheel may have advanced a half a revolution. If the sparks occurs during the compression stroke, the engine will backfire, and the crankshaft will reverse direction violently. If the operator was pulling the recoil starter, the starter rope would be pulled back sharply, along with the operator's arm. This is a common and painful occurrence, and a sure sign of a sheared flywheel key.
I'd want to verify that the "glowing red" condition is really happening all the time, or if that was just one case that you had from running it at 1/2 throttle too long and it being dark so you could see it.
you think possibly it could have been a tome time thing? that was the first time i noticed it but it was also the longest time id let it idle half way.. well even if its not the key i still wanted to get it looked over before the season considering it is a used mower ya know. JASON ROSE THANK YOU FOR ALL THE HELP!!!!
Sorry abouit the bad advice. I don't actually own any engines built in the last 15 years so I guess I'm not that up to date. The timing thing makes good sense.
whats this shop called that sells the walkers and where is it located?
Since its EFI and not running smooth you have a fuel injection problem. Probly need new injectors. The injectors are giving it to much fuel so its burning way hotter and since its a v-twin you have about 4 times as much exhaust going through the muffler and alot hotter so it is making it heat up and glow.
I would change the fuel filter. its an item that gets overlooked all the time. Also make sure your cooling fins are clear from any debris. If their clogged up it will make hot spots on you cylinders and increase wear.
