help with engine

What are you talking about? Deaf AND senile...

Seriously, counter clockwise, just like a hose faucet will allow more fuel, just like more water in the hose. Clockwise will lean it.

I was just giving you some grief. Didn't you see my fancy editing?

Thanks for catching my goof!

 

[Rolex]

Fess up. Admit it. You were WRONG!
How's that for grief?

 

[RC Addict]

Meh... Been wrong before. Will again. That's the difference between qaart and myself...

 

[Rolex]

You just ruined my entire night. I'd almost forgotten about him.

 

[RC Addict]

Sorry buddy!

ok thanks for your help, ill post what i find out when it warms up a bit at the moment its freezing, around noon should be warmer

If it's that cold, you'll also need to wrap the cooling head to keep the temps up. It's very difficult to get good performance in the cold since engine temp effects how the fuel mixes and burns. It would also help to pre heat it with a hair dryer.

yea i have tryed eveything you guys said, I'm still having this problem, when i run it a few mins and its hot, if i stop the truck and let it idle it will die and not restart..

 

[Rolex]

When it's running, do you get a good punch off the line, or is it sluggish? What about top end?

 

[XxVASSAGOxX]

good off the line, clutch is weak but when it takes off its strong top end is fast

 

[Rolex]

I'm gonna' take a shot here and guess that you're running too lean. As the weather gets colder, the engines need more fuel to compensate for the denser cold air.

 

[XxVASSAGOxX]

yea i been letting it cool down, then I'm doing 1/4 turns richer and running it, nothing.. still the same gets hot and woulnt restart after stall. till cold again

 

[RC Addict]

I am back to my original theory. You have an air leak that is leaning you out. Did you do the air leak test, and did you do the pickup line test?

 

[XxVASSAGOxX]

yes i did both things you told me to do, found no leaks...so far... can the COLD weather affect it this much ? its 40 degrees today, also can you tell me the factory setting on the HSN for a trax nitro rustler??

 

[Rolex]

If it's getting hot after richening the HSN, it's the LSN that's too lean. If you richen it and it runs cooler, you're fine. If it doesn't help it and it starts to get sluggish off the line, you've got a leak somewhere.

 

[XxVASSAGOxX]

how should i go at the lsn should i back it out to very rich then lean it out slow?

 

[Rolex]

No. When it's cold it starts. Start it and let it warm up a bit, then richen the LSN by no more than 1/8 of a turn out. Run it and check the temps. You will get slightly less punch off the line, but that's the price you pay for running in the cold.
See how it behaves. If necessary, richen it a bit more till you can continue running it. WOT will probably need to be tweaked with the HSN once the low end is good.

 

[XxVASSAGOxX]

is 40 degrees to cold to be running my rigs?

 

[Rolex]

It's too cold for most of us because we can't really get proper performance below a certain temp. They get really picky about the tuning.
