Carb Q's

[warriorrider13]

OK two things: When I hit the throttle really fast it just bogs. and the other question is, isn't it if a short blast of fire shoot's out the exhaust the carb is to rich?

sounds to me that it is to lean if it is boging down when hittng the throttle fast and its back fireing out the carb not getting enought fuel open the fuel mixture screw up a bit and see if it gets better

 

[warriorrider13]

the mixture screw is 4 turns out! I think it is maybe my main jet. But I have never touched the main jet.

 

[87warrior]

it recalls for it to be 2- 2 1/2 truns out that might be your prolbum there

 

[warriorrider13]

if it is 2 - 2 1/2 turns out that would just make it even leaner.

no...the further the screw is out the further the needle is out of the carb...farther out allows more air and less gas turning it in will bring the needle closer and therefore there will be more gas, (riching it)

 

[warriorspeed350]

seriously....listen to the guys with the edelbrocks

ok i might be wrong but I was looking at my carb today and the more you turn the screw in the more it pushes up on the piece the throttle cable pulls there for the more in it is the more open the throtle in (richer)

He said it is back firing out the exhaust.

It's not the same as adjusting the edelbrocks - the fuel screw on the stock carb is richer when you back it out.

I was shooting 6 inch blue flames out the exhaust for a while, and it was because it was too lean. If the fuel screw is out 4 turns and still popping first you should check for leaks in your intake and exhaust, then if everything is good there then go up a size or two on the pilot jet.
