Default .25 carb settings

ok i just bought a used .25 savage that had the motor just rebuilt on it. he said that he put the carb setting back to factory but when i finally got it started it pulls sooo slow about 2 mph. i kept trying to lean it out thinking that he got the settings wayyyy to rich but right away the hsn screw was all the way in. i didn't get a book with it and was wondering if anyone can tell me of a websight or just tell me the carb settings so i can go from there.

i got a .25 motor and i got the mid range needle in mine as well. it starts great like first or second pull after i put all the factory settings where they are supposed to be and i rev it up a little and it dies and fuel comes pouring out of the exhaust pipe but i lean it out almost all the way and it still barely moves. could my carb be screwed up?

is it easy to start? who did u buy it from? the only other thing i can think of is the engine is so worn out that there is no compression and there for it won't run strong or just won't run

i bought it off ebay and it said that the guy who had it before ran the engine to lean and this guy rebuilt it and sold it. i was thinking the same thing cause i can't even get this thing to pull itself then it is spraying unburnt fuel everywhere

oh and when i first started it today it took me about 60 pulls to get the fuel up to the carb and finally got it started. and it doesn't seem like i have to pull that hard to get it to turn over at all either.

i think that guy was lieing to u. he didn't rebuild it. to really test this, set all the needles to factory, then try to start it it should be easy cuz it's at factory. well before that just take ur finger and rotate the flywheele counterclock wise and see if there's a resistance. this is how u check the compression. if it's easy then the piston and sleeve r worn. also check to make sure the screws that hold the cooling head on are tight then do the procces with the flywheele. keep us updated with this

he says it is a .25 and on that video and stuff it doesn't show the .25 having a mid speed needle and that the .21 does. i checked all the cooling fins screws are tight and i can turn the flywheel very easy until it gets to TDC. then i can't move it anymore. i then checked it against my os .18 tm motor which i know is way smaller and i can turn that all the way through TDC and that motor is barely broke in. i wonder if i should take the carb apart on it.

taking the carb apart? it has to be somehow bypassing the fuel through the motor out the exhaust and i supposed if something is sticking inside the carb it will flood the motor and push fuel through ok so the theory goes

it's hard 4 me cuz i'm not there but try it take the needles off and everything clean it. also just remember hoe everything goes back. i got the idea from sombody film yourself taking the carb aprt and if u forget how somthing goes just rewind and watch how it goes back.

good luck

Default RE: .25 carb settings

ok, i looked at the hpi factory settings video. are those break in settings? because they did not make my needle flush, it made it a couple turns leaner from flush. i was wondering this, are the factory needles settings flush with the very top? cause mine came from the factory flush with the bottom of the angle in the needle housing. (the angle that starts at the top and ends about 1-2mm down) its hard to explain, but can somebody help?

i contacted the guy i bought it from and he was dumbfounded. he said he did rebuild the motor which i believe he did. he told me if i can't figure it out i can send him the motor back and he will send me another brand new motor for nothing. i told him i think it is the carb that is screwed up so i will see what his reply is going to be. he has 100 percent approval rating and he was very prompt and professional about this so far.
