78 invader 440 carb info

[invader 440]

i finally found some carbs for my invader. they are 36s with 150 mains, p-8 needle jets and a 3.0 slide cut away. the air screw is 1 and half and the idle screw is 1 and a halt turns out. it idles really hard when its running and when i fnally get it to rev up its like it sticks there and keeps reving higher but the slides close. what could it be yet? thanks

Do you have the belt on or off?  Without the belt the engine will often want to spin up.

When you say it idles hard, what do you mean by that? 

[invader 440]

yes the belt was off but what i ment was it would red line as high as it could. when it would idle it was running very rich and like it was running on one cylinder

rough set on idle speed is 6 turns out from coil bound.....i just had a 500 indy do that run away deal.....pto crank seal.....

[jimvw57]

air leak would be my first guess, crank seal (as Kawhead said) or possibly carb mount

[invader 440]

i did the crank seals and the carb boots are good. im going to waint till it warms up to ty to get it running again or sell it by then

3.0 throttle valve (slide).  If I remember Kaw uses 2.5.  The 3.0 slides would make the motor rich off the idle idle circuit.  Idle circuit sounds like you have an air leak.  With the seals changed that leaves the carburetor boots potential for issue.

Running on one cylinder.  Check with a automotive timing light and see if you have fire.  From cold start up hold the e pipe before the confluence to see if one gets hotter obviously first.

Balance the carburetors!  Counting turns out does not get the deal done.
