In my previous post i told how my carb gave me trouble after my engine got hot. (refer to post,.. "My wagon died from heat exhaustion,.. why")

I adjusted my idle speed up and now it idles ok.

 

Is the fuel supposed to be coming out of the primary jet when it is idling, (dosen't the idle jet do this while the throttle is closed?)

 

Why should my idle speed have changed?

 

Thanks

Now here is a RWAG (Real Wild A$$ Guess) for you.

 

I like the fuel percolation (i.e boiling) idea.

 

IF your bowl vent were closed or restricted and the fuel boiled

the pressure in the fuel bowl

collapsed or somehow impregnated the fuel bowl float.

 

Now the float is sinking and allowing too much gas into the bowl -thus it's dumping

 

this lowers the idle as the excess fuel is flooding the engine (fuel out of primary)

 

you turn the idle up to compensate for the excess fuel.

 

I did say RWAG

 

I'd check the float level

Does this mean pulling my carb apart?

 

My old man told me that pulling the carb apart usually means trouble getting it to run again once it is put back together

 

Is there any way to test if it is the diognosis you gave ?

sorry mate, ya gots ta take the top off

but it sure sounds like it's dumpin

 

no major dismantle.

 

just Pop the top.

 

 

aint ya got some mates around that tinker with tooters?

I couldn't tell if the fuel was coming out of the primary jet before (cos i couldnt start the engine and get to the front of the car in time)

 

but since i adjusted the ilde speed screw, it is now

 

and its only idling at normal speed (i turned the screw about 2 full turns)
