My stuff won't run very good when it get's in the mid 90's.
For one thing, the fuel expands greatly at that temp.
I think the carbs need to be adjusted but, some can't be done in the field (thank you EPA).
Don't fill them to the top with fuel and crack the cap a lot during operation to let the pressure out.
I discovered the pressure thing about 7-8 years ago and it's a habit to crack the cap every time I start something up now.
Maybe someone else has some ideas?

 

Try a higher octane gas. It will have lower volatility, so it won't expand as much in the heat. I only run 93 in my machines.

 

Pour Gatorade in the fuel tank. The electrolytes will keep the engine cool and hydrated.

I'm joking of course

I have alot of pre-ethanol 2 cycle equipment, and the new fuel P----es me off.

Buy a can of carb cleaner. You'll start on the first pull. Save your hand for....... ...

I think that is what 's happening. Only when it's in the 90's it really gives me problems. I try letting out the air by cracking the cap but it's not a magic bullet. Okay so I knew I wasn't the only one with that problem.

Yea, carb spray is what I have to use if It just won't start. Can't have my hands weak for ....:laugh:

 

An overheated coil/ignition can cause this.

 

Try releasing the gas cap. Could be vapor locked.

 

Try replacing it with new units

Rings get hot 🔥 so your compression is going by so when it cools off it should run better this is y I use two weeders run one out of gas ⛽ give it Break to cool off wow I use the other one and thi to keep them in the shed a when not in use..

 

Thread is almost 10 years old, tho probably a tip anyone could use.

 

10 yrs old or not, I'd start w/ a new and properly gapped spark plug just to rule it out.

 

I don't believe that a recoil assembly can handle a million pulls or that anyone would actually try that hard to start a machine, so I'm calling BS on the OP.

Edit- I did some calculations and you would have to pull the recoil once every second continuously for 11.5 days in order to try to start it that many times. That likely exceeds the limits of human endurance. Definitely BS!

 

Life changing experience to say the least.

 

Back in the day, it was an indicator that the Points were bad.
But now....
