problem after engine heats up, it dies
I start running my jato and i get a few shutdowns when i start (when everything is still cold) but after about 5 min i get every thing warm and drive it for a tank or two and then while its still a bit warm (5 min cool down) i start it up and if i let go of the throtle slowly it dies .. even after i give it a few runs it all of a sudden dies when i let the throtlle all off..
What should i change ??
o, its a 2.5 all stock
ya it could be the idle try to richen it also does it blog out or does it die for lack of gas to the engine if it blogs out lean LSN and if it dies from no gas richen LSN but still richen idle
the idle is factory setting..
It just dies out in a sec, i think you can say lack of gas?? im not sure 100%
I'll try richning up the lsn, and after that the idle...
I would start by turning your idle in so the carb's gap is about as wide as a credit card is thick, ie 1mm. Then after you start it I would do the pinch test and if it dies at around 3 seconds I wouldn't touch the LSN. Then just richen the HSN just a little bit. Then run it and see how it does. It may run just fine until it warms up after a few minutes and then you may need to richen the HSN slightly.
I just came back from a little session (2 hours) i askes a few guys to help me out, what we did was closed the LSN alot (bout 2 full turns clockwise) and opened the HSN abit 1/2 turn , we fideled around with it for a bit and then we set the IDLE screw so it will run a bit higher...
The car whent crazy, the throttle is alot more "punchy" and it sounds alot better...
Problem now is that it heats up alot... Can this be mostley becouse of the LSN, or should i open the HSN a bit??
Some1 down there told me that the LSN dosn't effect the temp as much as the HSN and i should open it a bit till it dosn't heat up...
Is this good advise???
Or should i try something else???
O, the car dosn't go off anymore, it runs on a bit higher revs (idle)
Sounds like your close to a perfect tune. When I drove a T-Maxx that had a perfect tune I was amazed. Not sure about the LSN not affetcing temp. You could try to see if it does and then put the needles back into the position they are now.
the lsn will affect engine temprature when the carburettor isnt opend much, as it affects the air/fuel mixture at low speed, it will affect the temprature.
What temps were you running?
What's the result of your pinch test?
One of the most common tuning mistakes is to set the idle screw too far CW (too fast) and the LS too rich. This will give you the appearance of correct running, but it is wrong. When in doubt, go the factory settings. Set the idle .8 - 1mm open, set the LS to flush with the lip, ser the HS to 4 -4 1/4 turns open. From these settings, you shouldn't have to change ANY setting more than about a half turn.
