UPDATE
I have not added more gas, because even though it quiets the popping, the intake manifold is coated in extra gas..
However I have figured out that my chain tensioner piece is broken. when i removed the top part of the shroud to check for oil leaks, for the hundreth time, i realized it was coming from the tensioner, and when i looked closer i could see it cracked in half. still in place, but broken. probably part of the issue there.
I have got to get this thing running soon, it's annoying how every time i get close, something else has to break.

I'm idling around 13-1500 when warm. and the thing that's getting me is it pops only when i lower the jet. i ran a 100, and it popped mildly, went down to  and it straight backfired, then went to 105 and it's quietly popping now. I can get that working, but what i'm worried about, is the smoke coming out of the manifold when i pull off the carb. it's not smoking out of the exhaust. |

It pops lightly on Accell, and my power is terrible. the manifold is new and fine, i just put a new spacer/gasket in so that's good, the exhaust is alright as well.
It seems to be going away as I up my jet, but My worry is that the manifold has smoke in it when i remove the carb. I wanna make sure that's nothing serious before i throw the 110 or 115 in.

So I have this little Jonway Agility yyqt-60 that i bought about a year ago second hand, it's 2012 was 50cc. Then i fried the rings on that after a little performance upping. So i installed a BBK in January of this year, and that killed my crank. So a few weeks ago i put this 44mm stroker crank in from STG with a new BBK and it has been a nightmare to get running. First the manifold gasket broke, i bought a 150 gasket, easy. Then i drained the gas (it had sat for about a month), now it started but still backfired and popped. My brother tells me his did that when it was getting too little gas. So i upped to 105 main jet and now i can start and run, but it still pops subtly and i get little speed. Like it struggles to hit 35 downhill. I have two more larger jets, but my issue is.. every time i took the carburetor off there was smoke pouring out of the manifold. it was just a clear smoke, not thick, so it's not leaking gasket or ring. Is this normal or am I screwed again? This thing has been a nightmare since i bought it. Parts list; - 44mm STG Stroker Crank
- 82cc Big Bore kit 50mm
- A9 Performance Cam with matching Rocker Arms
- Performance Variator with 6g rollers
- Standard Replacement belt (will be upgraded when wallet allows)
- Performance clutch and bell with 2k springs (i hear that's what most people run with the crank)
- 14/47 Racing Gears
- 60mm uni intake with 1.5-2.0in L and straight. (air is no problem)
