Hey guys, I just picked up a Savage XL with a Axial .28 spec RR motor, HPI exhaust pipe and it looks like a polished header.. I'm told to run %20 nitro mix by Traxxas. I've got a hi-tec? (I think thats the brand) steering servo with a HPI stock throttle servo.. picked it up yesterday and they guy literally gave me probably $1500-$2000 worth of stuff for $300.. it was a pretty great deal. so my current situation is that the car cold starts NO PROB, runs great for all of about 5-7 mins or 1/4 tank of fuel then _________________ flat line.. it refuses to start unless I play with the throttle on the receiver and hold it wide open while pulling, it'll fire up all crazy and as soon as I let off the throttle to let her idle she stalls... I can keep it running by feathering the throttle but its a minor matter of time until she quits. I swapped glow plugs, in between swapping glow plugs I turned the motor over a few pulls to clear out the cylinder and cool it off a bit but still struggling.. now, I feel (total noob with a decent concept of engines in general) that this is all tune up related, I mean, it's gotta be. where do I start? do I turn all the adjustment screws closed and pull back 2-1/2 turns.. do I take it to the hobby store and pay someone to do it.. I'm sort of stuck here. when I had the starting/running issue last I screwed with an adjustment that I'm pretty sure I shouldn't have, its a screw attached to the venturi.. it has an accordion looking tube with a needle in it.. I dont even know what it does or what I did all I know is I was frustrated and it seemed to hurt not help.. got real smokey (I was on and off on the throttle trying to keep it running) and would not stay running
I went to the hobby store today and the guy reset the high speed adjustment to stock spec and recommended I purchase a new radio because the stock one was really messed up, I bought a traxxas tqi 2.4 that seems real nice and on another note, tryng to start it after the 4th stalling problem the pull start cord ripped off in my hands.. i'm feeling discouraged...
give me guidance please!
