hey guys, i picked up a honda areo 125 2t.. beat to shit but she ran.(need a spare for my zx build)... anyway, it started, ran ok.... figured i'd check gas. it had been sitting for close to a yr. i cleaned carb this a.m, drained gas tank, now she wont hit... can some one help me with this.. got great spark, getting plenty of feul.(was running, so i figure leaks gotta be absent)... even took off air filter and choked it with my hand, still cant get a hit.... clean carb again?... last night when she fired, it would start dying out around idle, give it gas, it would bout backfire, then wind on out.....

If you have any doubts about how well you cleaned the carb, do it again. Check lines and filter for clogs. Check operation of the petcock.

ok brent, plz help a dumb ass out... how in the world am i suppose to install a bbk if i cant even get this thing to fire... cleaned carb again, cleaned screen. this petcock has an extra line coming out.. what would that be for?(1 fuel,1 vaccum,1 ?).. she fired right up a bit ago then died. kindof like you sprayed starting fluid in) getting fuel, now it fouls out the plug EVERY time i turn it over now. bowl stuck? took apart 3 times so far, bowl works.. i cant check for any air leaks till she fires.. no insulator in between carb/intake for some reason. but it is a 84 model too...lol.. i apologize for being such a dumbass but what am i missing here.... thenks.......

I'd wanna figure out what that third line is for on the petcock first. If it's on the tank, i really have no idea what it would be. If it's external it would be fuel in, fuel out, vacuum.
If a reed breaks it can cause fouling as well.

The BP6 is a hotter heat range and a projected tip. I would think the BR8 would work enough to run, but it wouldn't be a bad idea to get the recommended plug.
I'm thinking you have a good bit of excess fuel in the crankcase. I've had that happen once with a busted reed (guessing the non-sealing reed caused your problem) and once with a really rich pilot. I pulled the spark plug out, kicked the engine over a few times, put the piston to BDC so the ports were uncovered, and let it sit overnight or for a long period. Worked for me. You might still have to try and start it with the throttle wide open so it can get plenty of air though.

just went and put one of my plugs in for a test... she fired RIGHT UP.... ran for 30 seconds and died.. the plug was wet with fuel... so flipping the reeds over was a good thing since one side was open?.... so since the wetness, i have extra fuel in the crankcase??? never had that one.. i did move it inside the other day and when i put it in the shop. the carb started leaking fuel.. i forgot to turn the fuel off, leaked everywhere out of the carb.. just figured float was stuck but i never touched it, just wheeled inside.... so just try tomorrow??

do the stuff i posted above, then let it sit. flipping the reed was good if it seals now. may not have been all the reeds fault. Sounds like it coulda had fuel flowing in there from the carb. If you hear it slosh around you really have a problem and need more drastic measures. lol

i wouldn't have thought it would just keep pouring in the engine.... thought thats what the vaccum for? my zx never done that when the petcock died and flowed all the time.... still never found another end for this odd vaccum? line coming out the petcock on this aero either.. could it be an overflow tube?,fresh vaccum tube?...idk.. not long enough for anything... i have a proper plug on the way, put it on bdc and she is sitting... i dont think it was sloshing around.. :paranoid: ... the reed did look better after i flipped it for sure.. ;D

thanks brent.....i went this am and got her to fire up...smoked like a :swear: tho... i cant seem to get the screws right. wants to rev high, cant get it the wheel to stop. do you happen to know what the screw turns would/should be on a 125 2t. oh yeah, the screw on the intake side is the fuel mix screw?.. the one on the filter side is idle?.. that screw was around 2 turns out. the other screw actually had to be modded a bit by me so i can use it.(the tip is broke, filed a v so i can turn it).... also why did i have to dam near plug the inlet up with my hand to even get a crank.. hardcore choking... fuel?.. rings?.(i will do a comprerssion test with my pos tester from h.f for sake of argument).. shouldnt have to choke it out to the point of fuel spittin in your hand to fire, i dont think

i actually found a daelim e5 frame that i want to put this engine in. the daelim has the plastics and not as ugly as a aero frame..lmao (i think they are, not a big fan of that "euro" lookin type body style)...figured daelim would be easier than most to mod for a 125 engine. thats down the rd tho.. gotta get it running correct but i have a frame...

I'm not at all familiar with what carb is on your scoot. That said, the idle speed screw usually is visible inside the carb as well. You should see the tip of it holding the slide up to dictate idle speed. Another giveaway would be a spring on the screw. The mixture screw is usually kept in adjustment by a spring as well, but it's not generally visible without totally removing the screw.
Having to manually choke an engine that's out of tune is not unusual. Having excess fuel in the case puts it out of tune till it's burnt off, so if it clears up after running a bit it may be fine.

yeah that makes sense... :no: .. its a keihin pb18 on a 125cc stock aero.... almost the same as the pa14mm but you can change the pilot on these 18's....ok then, on this carb, the idle screw actually looks a tad bigger than the mix screw, which has a broke tip but works...i hope..btw, bothave springs, but yeah 1's visible. the idle ....on my other oem carb, the screws are on top of each other..
