Another carb problem ! lol

[202banshee]

Was on here about a month back asking a few ?'s about the shee was gonna buy. Well went ahead and made the deal today. Pretty new to banshees have done some 2 stroke work but not alot. Have done a chunk of searching and still kinda confused. If you unplugg the tors it revs to the moon, while plugged in it wont idle or run right. So I first noticed alot of slack in the throttle cable going to left carb (where to 2 cables meet to one). dropped that carb down making sure not to disturb the position of carb slide so I would know if it was off. Well there was a fair amount of grime and also the slides half moon cut away was faceing the reeds and not the filter(like I think it is suppose to from searching lol ) The choke tube was off also which helped but still wasnt right.The guy I bought it from had it at a shop getting some clutch work done and it sat there for 7 months and hasnt ran right since. He thinks it gummed up from setting and they took the carbs apart and got the slides wrong. Dont wanna even try going back to that shop lol. My ? is if the slide cut away is suppose to face the filter can I just turn it around or is it on wrong carb and I have to switch the slides --- and if so caps and all or just slides. Any help appreciated to bring this Banshee back from the grave LOL stock carbs

Also noticed that the slide has a vertical groove from top to bottom and the inside of carb has a flat protrusion inside of it that looks to me should run in the groove of the slide. But they are on opposite sides right now ?????????

anybody ?? Going out now to finish cleaning left carb and I guess try to just spin the slide around. Then off with the right for some cleaning. Any help wou;d be appreciated

[Screaming Yellow Zonker]

swap the carb tops side to side. don't pull just the slide. move the cap and all.

I just spun the slide around to face the correct way. ????? then kinda eyeballed it from back side and it was open slightly more then the right carb.Do the idle screws adjust this ???? But things look alot better cause all the slack is out of the cable now. Got left torn apart and cleaning hope to fire after dinner .... oh yeah and some tunning. :biggrin:

You should have a little slack in the cable....when you turn the bars lock to lock....you need a little wiggle room.

When the throttle is completely closed, the idle screws adjust the height of the slides.

 

I always turn each idle screw (TORS Removal kit) until I can just barely see it raise the slide. Then I turn it two full turns in to raise the slide for idle.

 

Then...using the adjuster on top of the cap, set these to where the slides pull (open) at the same time. It's very tedious, and I've spent 20 minutes getting them as best I can by eyeball.

 

You may have to turn the idle adjustment screws out 1/2 to 1 turn, but that's a good start.

 

Jeff @ FAST sells a syncrometer that you stick in the bell of each carb while the motor is running, it measures vacuum, and you can set the idle and carb sync with that as well..a very handy tool to have.

I should still have plenty of slack for that. Now both carbs have the same. What I had before was crazy-- were the 2 cables meet the one the lt side cable had so much slack that the protective cover was hanging down and you could see bare cable. LOL That will happen when you have slide in backwards and it has no groove on the side it needs to be ... I guess !!!! Thanks for alll replies and keep them coming THANKS

Ok took a minute but she fired up and sounded excellent compared to what it did. Idled fine maybe a tad high. Seemed a lil lean to me (not sure why lol) of course I didnt have the breather or air box on. But now my next ?

 

Turned the idle screws all the way in and out but no diff. Doesnt seem like they even touch the slides. Never seen the slides move at all while going in and out. Not real sure of all the mods it has but it does have the tors caps so I am thinking factory idle screws. It idles fine BUT HOW !!! I am so close HELP

[RZBansheeMan]

I'm assuming that with the TORS caps on that your turning the air screws and not idle screws. Chances are, most likely you don't have idle screws on the side of your carbs. I do believe that the idle adjustment is on top of the TORS (a big headed screw the size of a dime maybe).

Dunno for sure LOL I was assuming the ones on top you talk about were to synch the carbs only. And the ones that protrude out the side were idle screws and the small countersunk ones were the air screws. ?????

 

 

Just got off work and went out to see how it fired up. Kcked till i bruised finnally got mad (I know its not good BUT) gave a small squirt of starting fluid. Fired right up and ran fine. Then it fires easily after that. The TORS is definately shot I plugged it in just to see if it worked and ran like trash dont need it anyway...

 

My question is anyone have a reason or pointers on why its so hard to start the first time. Any help to send me in the right direction. THANKS

Your idle adjustment is probably a little high, When it is higher, there is not as much fuel drawn in when it is kicked over. It sounds like you need to reconsider some of the suggestions above. When your TORS stock top is on, the idle adjustment is by the big knobs on top of carbs. The synchronization is done by the cable adjusters when your slides are not resting on the idle screw.

P.S. Make sure that the choke cross-over tube is connected from one carb to the other or it will always be hard to start when cold.
