Hatchers Rocks!

[Jeff K]

Just want to say a big THANKS to Hatchers for the "no start" tip he has posted here a few times.

Turn on Kill Switch (so engine won't start)
Pull rope 3-4 times
Turn off Kill Switch (so engine will start)
Put throttle lever to the bar (wide open) and pull once and it should start.
Feather the throttle to keep engine running for a couple seconds.

It works great! I have only had to do it once, but it worked just as he says.

Thanks Hatchers!!

LOL......sure he'll correct me if I'm wrong, but it was another guy in a post that taught it to him!

It works!

Alright!!! How have I missed this post??... Something new to try!! I have to admit I'm sceptical and my TM7 has got to be one of THE BIGGEST HEURS to start when shut down hot... Or at start of day... And I always let idle after hot...

I need to put a switch in that heat soak sensor circuit too... Well maybe not?

Hey, does this work for the first start of day? Or is it a hot thing??

Pretty much the cat coolant sensor is all hosed up and presents a bunch of problems. I have heard about the heat soak problem but never experienced it with my sled.

I did however have my coolant temp sensor connector become unplugged. I could not see that it was unplugged, but was able to ride / start it only using the procedure mentioned above.

When the coolant temp sensor is open (unplugged) it will flood the engine if you do not hold it WOT when trying to start. If you pull it over 2-3 times with a closed throttle and open coolant sensor, it will flood and you will have to pull the plugs.

This all took me quite a while to figure out and actually had to get towed out before I figured it out.

That being said, I think the reason why this works is that the coolant temperature sensor is finicky on both sides of the temperature curve. Sometimes it thinks the motor is colder than it is (like the sensor is unplugged) and makes it too rich, and sometimes it gets heat soaked and makes it too lean.

Its almost like a 3 position temp sensor switch would be useable. One to close the coolant sensor connection, one to open it, and one to let it function as designed once you get it started.

Anyway, thats my take on it, I might be wrong, so take it with a grain of salt, just my experience.

Any brilliant minds figured out a solution?
