Can starters overheat?
If power is supplied continuously to the starter gear, it will eventually overheat. This is either because the starter has been operated too long without a rest or there is a connection problem. Smoke coming from underneath the engine, accompanied by a burning smell, can be a symptom of serious problems.
Why does my car starter not crank when it’s Hot?
If your starter easily cranks a cold engine, but “drags” or cranks very slowly when hot, there may be a “heat soak” problem. Before you condemn the starter as bad, you should perform a system diagnosis of the battery, cables and starter.
What happens when you heat up a starter?
Once under-hood heat warms the battery, cables, and starter, a “tipping point” is reached concerning the overall amount of resistance a starter can accept (and still function properly).
Why is a hot engine hard to start?
Most of the reasons by which a hot engine would be hard to start are based on problems related to the fuel. When the engine is too hot, fuel can’t circulate properly due to the way in which vapor obstructs it and therefore the engine wouldn’t start as easily as it should or it wouldn’t start at all.

Why does my lawn mower not start when it’s Hot?
Examine the plug cap for arcing and the coil wire for chafing. If damaged it will cause intermittent no start. Higher temperatures create higher resistance to the flow of voltage, that’s why coils usually fail when the mowers hot, and starts working again when the engine cools.
What happens when there is no key in the ignition?
When there’s no key in the ignition, no power can be sent to the rest of the needed components to start the engine. There are some pretty simple ways to get around this though. Of course the easiest way is if your machine has a pull start or kick starter on it. A lot of the newer quads being made don’t have this functionality anymore unfortunately.
Why does my outboard engine not start when hot?
Four stroke engines that start up when cold but won’t when hot usually have valve problems. As the engine warms up, the valves expand and don’t seat as well causing a loss of compression. As long as the engine is running, it usually keeps running.
What should I do if my car won’t start when hot?
Try a shot of starting fluid when it is hot. If that works, the carb is the problem. If the mixture screws need to be reset, the starting point is 1-3/4 turns open (on both high and idle speed screws) from lightly seated. Checked the settings on the carb.
Until it cooled off, it won’t start no matter what you do. Lots of reasons may have contributed to this problem but the main culprit is most likely the failing coil. It’s so frustrating when you checked the oil level, air filter, and so on but the lawn mower won’t start when hot. If you have a Briggs engine, you will face it a lot of times.
