Carb clean abs rebuild help

[declan]

Got a 210 main jet is this too small? Complete air box dep muffler big one chamber looks like a 7.5 idle jet? I have a lean condition temporarily got a washer heightening the choke to counter act the lean condition what jets do you reccomend

[finnerz89]

210 main is standard size, I'm running full exhaust on mine with standard jetting and it's fine.
Have you checked for air leaks anywhere? What position do you have the needle clip in? What about the air screw?

[declan]

@finnerz89 air screw is seized clip is in richest position no air leaks

[finnerz89]

Any leaks on the exhaust system?

[declan]

@finnerz89 no all that’s good I’ve put it together and need to clean my petrol tank out so I will let you know how it behaves tomorrow

[declan]

@declan everything is done but it’s still running lean so the washer will have to stay on for now rode it for a while and the torque is much better wheelies off speed bumps in 3rd now so loads better

[Calum]

If it's running lean then you are just asking for trouble.

I would highly recommend getting the fuelling sorted before continuing to ride it.

[declan]

@calum I have by way of a washer heightening the choke ever so slightly it’s my only option right now and it runs beautiful

[Calum]

@declan I'm not even sure how you've done that.

[declan]

@calum I’ll get you a video tomorrow

[terry.tz]

@declan playing with fire

[Calum]

@terry-tz Yeah, kinda my thoughts.

Depends what he has actually done though. But doesn't sound like it's addressing the issue...why is it running lean?

[declan]

@calum seized air fuel screw no means of getting it out yet it’s proper in there litteraly just fitted a washer to the choke push rod to richen the mixture

[declan]

@Calum It did more than address it it fixed it no stuttering from idle revs nice and clean

[declan]

@calum think I’m running ever so slightly rich when I’m riding And come to a stop the revs are really low but it doesn’t die it’s fine when riding and when it’s idling before and after I’ve been out

[terry.tz]

but won't this mean you have less 2 stroke oil going through they seem to send a fair bit but your changing the mix at all rev ranges so it might be rich at 1-3k but very lean at higher revs

[finnerz89]

@terry-tz the 2 stroke pump runs off the throttle so won't be affected.

[Calum]

@finnerz89 It's driven off a nylon cog directly from crankshaft. So yes and no. It is driven from both the throttle and crank.

[terry.tz]

but the choke is not and you are putting more fuel in from the choke I don't know just saying its possible and when your at mid revs the choke might not give either fuel also and from my understanding, they lean out mid revs before getting rich again so could be a problem just what I would be thinking about if it was me I mean I would try what he has done, to be honest, but I would be like to fix it asap

[Calum]

@terry-tz Hey, ditto...
