cuts out at low speed and bogs at high speed?

[freerida69a]

ill keep this short and to the point. bought a jato 2.5, ran it for a bit, broke a shcok tower, blew up my revo 3.3 so i swapped my 2.5 over to the revo. messed with the needles, wouldnt run right. got a shock tower and swapped my 2.5 back to the jato. now i figured out it had bad gas when it was in the revo, got new stuff, now I'm tuning it and it will run but it cuts out on the low end and on the high end. I HAVE TRYED EVERYTHING, from 3 to 4 turns on hsn and below and above flush on the lsn. my tank and fuel lines are good.

Exhaust leak, check the header seal and pipe coupler. Could very well be bad fuel still. check the Carb needle O-rings and needle housings. The slightest piece of debri on a needle will cause your condition.
You may have lost pinch or the engine bearings are worn.

no exhaust leak, fuel is for sure good. i will go and clean the carb right now and i forgot to put in a screw for the ez start(when it was running good) and when i put it in it started running bad. but when i forgot to put it in it was oozing mass fluid? engine bearings would be the problem then right?
