have an Lst2 with 9 tanks of fuel through engine,,,when i give truck gas/power truck sometimes moves fast ,like normal ,,,but then sometimes it just likes looses its power ,,,ill give it throttle and it will got go anywhere,like it will struggle to move,,any guess why ? kinda new to the nitro scene,,,

its weird...at times the truck will power up fine,,,then after like 8 minuetes of running the truck just wont move,,,no matter how much power i give throttle,,,i picked up the truck and gave it throttle and the tires arent moving,,,,

It maybe as simple as it's to rich. Have you started leaning it from the factory settings?

Is the engine reving but the tires arent moving? If thats the case it could very well be the clutch or the owb in the trans.

let us know if it is fixed....

again,,,thanks for that pic 2D,,am working on the owb now,,,will let everyone know ...yes i have been messing with the needles...just the high speed

what is the temp?

temps were 330 f ,,,,,not good i know

you should be running at 220 to 250 no more than that or youre pretty much killing youre motor

WOW rish your motor before you blow it.... it's not your motor... did you try your slipper ?

could be the slipper...should i tighten or loosen it ?

found the problem...the clutch bell had its screw come off,,,ill take some pics and show you what i mean,,,also lost a bearing and a washer,,,ordered them last night from killer hobbies...

also ordered some new spur gears,,,the originals were chewed up

doesnt make sense how that would let it run fine for 8 minutes and then crap out...
