Haha ok heres my soap opera of a story, sad i know, but pleez i need help

Ok It started with me selling an antique tamiya super champ on ebay for like 300 dollars.
I was really into monster trucks and had a lot of friends with them. I decided to try and buy a cen genesis off ebay(used, worst descision of my life), and got one for 375. Now i have never actually owned a "Nitro" car, so this was all new to me. I got it and found out first off that the "Rotot-start" was shot and so i took it to my local hobby shop. I bought fuel glow plugs, charger etc new roto. the guy told me the starter was done as well as the one way bearing. So i went to another hobby shop where they told me the carb was shot. long story short (haha not), i totally replaced the engine with ebay parts,(crankcase, piston, carb etc) I then got a pullstart and after a couple dozen teardowns of the entire engine, i started the break in process. now i had not gotten my clutch yet so i did not use any electronics or clutch system while running the first 4 tanks. These ran fine and i got my clutch and set it up. I then ran 1 more tanks. with 5 tanks in it i hooked up the electronics and started anothertank. i dont really remember it was a while ago but i guess it just started up finebut after a while i took it off my homemade stand and set it down. i started running it in circles. it was ok but had a really ruff idle. i had been using duratrax hot plugs and they would like foul up (not start with the glow warmer fully charged) so after using up like 5 plugs my dad got me some mccoy hot plugs and when i wnt to start up my truck, it would idle kinda rough then sound like it was starving for fuel and rev full on and i would shut it off. Its not like a rough idle thing i dont think i mean i tried pressing on the throttle and it would rev up a little then keep going all the way up and man that thing gets loud at full throttle. i cant even stand next to it. anyway im sure its not the radio because there isnt any seen interference and the servoi doesn't move and i took off the air filter and inspected and it flows smoothly. I just dont get it. Any help would be appreciated. I have not contacted CEN since its prolly not covered under warranty. the pic is off ebay before i bought it but i havent changed anything major besides the block.

Make sure you dont have any air leaks where the backing plate bolts to the block, or around the carb or anything. If it sucks air it will be hard to tune, and run lean. Im not a big tuning expert on nitro's, but that is the little bit of info i can give. If you are at factory settings, and everything is put together right it should run right.

your in kinda a mess ill try to give all the help i can first its not recamended to use a hot glow plug on an engine .21 and above next get some soapy water an extra peice of fuel line line remove the air filter and the exhust put the extra line on the carb hold your fingers over the carb hole and the exhust then blow in the line while appling the soap water all over the engine especily around carb seal and the needle valves around the head under the cooling fin and the backplate if you get any bubbles you will need to take it apart and seal it up get on cen website and find the factory carb settings from what you have said you have an air leak which will cause the idle to be crappy i recamend a mc9 glow plug also check the fuel tank and lines for leaks the same basic way check and make sure the carb is opening all the way
