Engine help

[neebles]

Just got my clone put back together, trying to get it running, it starts up no problem with the choke closed, but dies immediately once I start to open the choke....Any advice as to what needs to be done to keep her running?

 

[devino246]

try adjusting the idle, it may be set too low

 

[neebles]

If we set the idle any higher, it takes off, so I dont think that is the problem.....

Clean the carb, sounds like a blocked jet.

 

[neebles]

Ill give that a shot, I just had it all apart and put it back together....So I will do it again

 

[neebles]

The weird thing is, we had it running like a banshee 2 weeks ago, but it would die when we let off the throttle.....

 

[neebles]

I have not tried to clean the carb yet, but as a back up plan any other thoughts or ideas?

 

[solomon]

You had the engine apart? Sounds like you need a new intake gasket. The reson it uns with choke it because its sucking alot of air in somewhere else, and when choking it, you cut off the air on the carb, and allow it to force more fuel. Replace the intake gasket and if that doesnt help clean the carb

 

[neebles]

Awesome, im ordering some new gaskets, gonna swap them out, Ill clean the carb while im at it......

 

[neebles]

So i replaced all the gaskets, gave everything a good cleaning, and it still seems as though Im losing vacuum somewhere once the choke is open. I do have an intake manifold with pulse fitting after the carb, so I can run my fuel pump, would it be possible that that is somehow causing a vacuum loss?

 

[solomon]

have you tried removing it from the carb?

 

[neebles]

I will give that a shot. Also, we have noticed that when we pull off the air filter, there is gas pouring out of the carb......

 

[neebles]

ok so we took off the manifold spacer/pulse fitting and it runs fine, so obviously it has to do with the pulse fitting. I dont understand why it wont run with the darn thing on there......darn thing....

 

[solomon]

can you take pics? are thier gaskets between the pulse fitting?

 

[neebles]

yep this kart hates me....

So, there are new gaskets, everywhere there should be, clean carb, clean spark plug, we have gas, spark, compression...It turned over once, got going for a minute, died, and we cant get it to do anything now......

 

[solomon]

sounds like a clogged main jet then.

 

[neebles]

We cleaned that out too, the carb is spotless.

 

[solomon]

will it run if you spray gas or starting fluid in the intake?

 

[neebles]

That will be my next move

the float might be flooded in the carb. That would make it so you see gas comin out of the carb.
