well i went out today to try and get in some run time with the car and it was running good before today so i try to tune it and it progressively gets worse and now i go full throttle and its doin 10mph most and its sputterin down the road...i cant figure out how to tune it im on the verge of throwin it as far as i can.

some one please help me out i wanna get this thing running like it use to i cant seem to get anything right.

ive already done the factory setting thing with 4 turns out with the HSN and im not sure what the LSN is suppose to be (as in turns out) but someone help me please

just turn it in 4 turns out is way to rich i would say just put it at around 3 or 2 1/2 if more slowly tune in or out 4 is too much i would say

alright thanx

make sure your running with good fuel (newer fuel)

yea i just bought this fuel like 3 weeks ago

i took apart the head and cleaned the piston (which was dark black) and the glow plug(also dark black) and ill run it again tomorrow

Holy crap you have been running rich!!![sm=eek.gif][sm=stupid.gif]

or very lean and it's been detonating

so is it rich or lean??? ill run it tomorrow and see what it is again

i cant figure it out my motor holds a tune for like half a gallon and then it does this every single time

i would say rich try leaning out

Turn your hsn in till it hit's the seat.Turn it back out to 2 3/4 to 3.Make sure your lsn is flush with collar and try it.It should be pretty close.Any more than 3 1/4 is to rich.Might wanna throw a new glow plug in aswell.Also make sure your air filter is clean and not overly oiled.To much oil on your filter will make it rich.Good luck and keep us posted on your results.

could be losing compression...

how old is your motor?

my motor only has maybe half a gallon to a gallon ran through it i bought it last year before i put it way for the winter

alright ill try what you said 241 racing and ill let you know what i get i gotta pick up a glow plug on my way home so ill test it when it gets cooler tonight

lol...I tune my engines every outing. holds a tune for a half gallon? GEEZ...I guess I DO need a TRX2.5!

Just because the engine doesn't have much fuel through it doesn't mean that its not wrecked. Is it hard to turn the flywheel over by hand?
