its weird, my rpm drops when i sqeeze the throttle, then it picks up and goes crazy fast after a few seconds, also i can't get my car to sit still while idling, the cam slide is only open about a millimeter and when i close it off anymore buy ajusting the throttle screw the engine quits? need help please?
 
Yup. He's right on. Your Low Speed is too rich....and you probably have a clutch spring dragging or broken.
 
ok thanks ill try ajusting low speed, tho when i do the pinch test it quits right away, i heard that was a sign of it being too lean so i kept making it richer. i wish i took note of the factory setting b4 i started screwin with it lol. and so the clutch spring is the one inside the 2 speed gear box? the one you can ajust? or do you mean the springs inside the clutch bell that hold the clutch shoes on? sorry for so many questions but I'm a total noob haha
 
Put the low speed needle flush with the carb slide body.

The spring in question is inside the clutch bell.

Your lsn could have been too lean I guess, but you'll have to help us guide you better. Get it warmed up and see how long it will idle for. It should have a nice clean sounding idle for at least 10 seconds and then start to 'load up'.
 
What engine is it? Generally a good setting for most is set the needle flush with the housing on the high speed....and flush or close to flush on the low speed. Just note that flush on the low speed might be WAY too rich for some engines ;-)
 
its a ofna force .32 i ajusted the lsn leaner and its going great now thanks guys. the idle issue of it moving without throttle is the same tho. no springs one the clutch shoes are broken, but i think i bent them too much while putting new shoes on last time using a flathead screwdriver and they are pretty easy to take off one one shoe is off. ill try bend them back the otherway and re-aply them if all else fails ill just get some new springs. thanks again for the help :D
 
There's also the possibility that your idle screw is just set too high. You need to find the balance between the LSN and the idle setting.
 
yea it was loose springs, got it to sit still at idle now :D. but took it out last nite at like 3 am to a carpark for a thrash and i couldnt get it started at all? it was pretty cold about 5 degrees celcius and really foggy, i tryed ajusting the lsn both ways a little and got it to start for a few seconds before dying but just gave up in the end coz i didnt want to mess with the settings that took me so long to get right for normal weather driving..so how much does weather and fog affect the way it runs? also does keeping it outside make a difference like does moisture build up in the air filter?
 
Outside temp will definatly make a difference . If its cold out or a cold breeze i always heat my engine up to about 25 . And then put a sock round it or something to keep the temps up .
 
everyone is saying rich and there not wrong but ushally when its got a rich lsn it just stops and cuts of and trust me i had the same problem and it sounds abit like its going to die and i found the the lpn was to lean
