Is your idle set right. Look in the carb, when full brakes applied there should be about a 1mm gap

is that a wasp .28 or .26? the .28 uses a turbo glow plug that is what your using?standard plugs are used on the .26
i had more then enough wasps to know that they are tempermental,check your idle set screw when you brakes applied while idling,and you glow plug should be a med, i found this to be the best epescially the ofna med turbo plug works great with fuels from 25% to 40% i use 25 and 30% fuels and they are set 2 turns in on low and med screws,but these engines are tricky when it comes to tuning,,

try tuning while on a box hitting the throttle every now and then the after you get get where it kicks good set it down on the ground hold front tires down and crank the throttle to see if your bogging ,your trying to get the engine to recognize the back pressures from the drivetrain,run it moderatly in a small area in quick bursts again the engine needs to feel the weight of the truck on it,

this works for me i do this for about 3 tanks constantly checking temps as you adjust the needles these engines are at home in the 280-300 degree range mine are hitting 289-295 range and are wheeling on a dime i still get lots of smoke and a good oil drip

all else fails maybe i can meet you to help this out in person

I have it set as the book tells me just so i can get it to Idel and yes i got all kinds of plugs and yas it is a .28 Turbo i tryeda Turbo 5.7.8 and nuthing works it works good when it is cold but when it heats upstarts runing like Crap

Im going to the race this weekend im going to Bring the moter for back up up im going to run my .26 in my Savage.. Not going to run the MGT right now i cant trust it

mid needles shouldn't be messed with from the factory. Those are preset from the factory for the easiest tune on the LSN and HSN.

If it runs like crap after it heats up that tells me it's getting too hot. Either your LSN or HSN are too lean.

I can't tune your truck from here but I can help you at the race on Sat.

ok cool this is the only moter i have evry had a Problem with i got all kinds of moters.

[grim digger]

these are the only motors i have bought in the past yr half and it took me some time to feel it out but ,i use no others now,in the end your going to have to adjust both low and med screws med plug and 25 % trinity or what ever is decent,
if all else fails how much i'll buy that bad boy if the price is right and if you can not tame it,LOL

[Fatso_TRE]

i payed 169.99 for it and i got it tusday Night. im ruing 20% Nitro and 14 Oil that what i run in my Picco .26 and it run GOOD sould i change that out if you want to buy it off me u can make me offer on it if i cant get it to work i just take it back and get a nuther one ? my get a nuther .26 Pecco Not sure i like to get it working in my MGT we will have to see .... any of you guyse live by or in DeKelb?

[grim digger]

hmm,try to get tuned before doing anything if you can not then
if you can exchange it out for another go ahead that is better for you,but if they dont take it back
i can offer $145.00,but wait till tex or someone at the track can try get it tuned before doing anything

Mid needles can be adjusted but.. u have to move the lowspeed accordingly. So if u move the mid speed needle in 1 turn u will need to move the low out 1 turn. But really not worth messing with.. it changes where the hit comes in on the powerband.
