Hey i own a cen fun factor subaru and there is a problem i need help with when u apply full throttle to it it runs fine and everything until its about to change gear where it then stalls i dunno if it is changing into 2nd gear but it doesnt sound like it anyone that could help that would be great

Does this happen right away or does the car run fine for a couple a minutes and then start to act up? Check the head temp with gauge or using the water test because, you could go either way with the HSN but it really depends on the head temp.

stright away

sounds like its to lean on the HSN... turn it out a little, also i find nitro engines hate going full throttle when there still cold so try driving around for a little while slowly giving it more and more throttle to get them temps up[8D]

hey thanks for the advise i think it was running to cold when i tried to get it going thanks

OR it could be to rich and flaming out, How Old is it and how much Fuel have you ran,, answer these befor you go screwing needles about... lets get an idea of the condition of the setup. then a more justified resolution can be pinpointed. as Todd Said, it could be either way... you could be getting lean, you could be flaming out, you could have a leak in the fuel line that sux air when drawing more fuel faster, or a crack in the gastank.. you could have a lightly loose flywheel> let get a full rundown. your engine could be so new its doing some normal things. if new i hope your not wotting it already or you troubles could just be beginning.
provide a more detailed assessment of whats going on so we can help you to stop chasing your tail befor you even start to chase it.

hey thanks for all the help it turned out to be it wasent hot enough when i tried to get it to change gears

It could be that TOO. which is usually helped out by overly rich and not being able to get enough heat generated.
If theres one thing i have learned when dealing with nitro< Adjusting your needles is only done AFTER you have eliminated ALL other possibilities.... Im startijng to come to the mind of, once running good, any issues should be fully investigated BEFORE the screw driver is Touched...

Timmah is right and i would of said the same but I was %95 sure it was to do with the engine not been upto heat, my cen used to do it when i had the 2 stroke in it the first start of the day you would need to tak it easy. once it was upto temp it would run great for the rest of the day... even if you stopped using it for a hour or so then went back it would still run great, just the first start of the day (who likes been woken up in the morining and asked to do hard work right away) ... My t-maxx is the same.

Also, never ever ever tune a cold engine! Make sure it is at operating temperature before tuning begins.
