HELP with tickover please.

[shedjim]

Hi all. I'm new to Large scale petrol but am loving it.
I have a FG monster truck (E bay) with a cleaned and oiled K&N filter and standard pipe.
My problem is that when braking to a halt my engine cuts out. It seems to get worse the hotter the engine gets. It runs Fine all other times and starts and ticks over straight away.
I have checked spark plug colour,air leaks,servos set correctly mixture scews set to 1 1/2 H 1 3/8 L.
I have been tinkering with settings but a near fatal accident halted testing on sunday (hhhmmm have i got the cash for ally bits ??????hhhhmm)
Anyone got any ideas or do i just need more tinkering ????
Cheers Jim.

mine was doing the same thing its to do with the linkage

where the throtle spring sits and stuff

have a play around with that moving the grub screwed bits (forgot name lol)

sounds to me like gasket,did you check to see if there is a gasket blown/leaking if there is anysign of oil leaking there you are drawing air on return piston stroke.

either that or your carb is drawing air someplace!!

take off carb and check it meticiously.

if either of there fails you you have a piston ring/compression problem that only raises its ugly head when the heat makes it a problem to hold compression from heat expansion.

I would also start 1st with your throttle/brake set up.

With the motor off look at the carb arm that the linkage is attached too.



Is it fully closed or is it slightly throttled?
You can also look to see if the other side of the arm is hitting the idle screw.



If you find its throttled up slightly adjust the linkage or TX to close it off completely. Then you can use the idle screw to idle it to a purr.

Check your EPA's and idle adjustment screw. One last thng chuck that air filter it will greatly shorten the life of your engine.

Go back to the FG stock filter with a Redneck wrapped around it. The K&N's are more for on road. IMO.

Many thanks for all your help.
I haven't played about with it yet. Whilst fixing damage to truck i tried to take my finger tip off with a stanley knife, not my best move, so now i'm in a worse state than my truck.
Hope to be able to play around again at the weekend.
Thanks again for all your help. Will let you know how i get on.

LMAO you went to my same school of mechanics I take it. I usually dremmel my fingers though or drill bits. Be like Tony Iommi from Sabbath and glue some small thimble to the finger tip and get back at it
