That was the guy in the service shop I talked too. He seemes to think the thing has other issues, he told me the jet size would do nothing for my problem.

Here's what I am thinking. The carb has to draw air over the needle to generate the vacuum to draw the gas through the jets, out of the bowl correct? If this hole is normally plugged, but is now open, when the throttle is cracked, instead of drawing the air through the throat of the carb, therefore creating enough vacuum to draw out the gas, it is now drawing air through this open port. This wouldn't allow the mixture to reach the engine, and stalls it out. What I need is to see another carb to see what they have for ports. You can actually hear the air getting sucked into that port when you crack the throttle. Anyway you can take a pic of your carb with the intake hose off? I'd love to invest in a better carb, but the $ isnt there right now, unless I could find one second hand. I'll probably just run this as is for a while once I get it going, and then invest in it down the road once the funds are there.

 

Air goes thru the venturi, which creates a vacuum, but most of the vacuum comes from the airfilter restricting airflow thru the carb. Adding to this, if you have less exhaust backpressure and a decent valve overlap, vacuum at the carb will increase because escaping exhaust gas will pull air thru the carb easier if you have less backpressure.

On my setup, I have a KN filter bigger than most car filters. The only way I'm getting less airfiter restriction is to run wihtout a filter altogether. Because of this, I have to run a mainjet that is about as big as the needle-jet. Plus I have a dial-a-jet squirting gas in there. The carb alone will not generate enough vacuum by virtue of the venturi unless the carb is really small.

Its a big production to get the carb off my bayou. Not only that, but I'm using the bayou to move dirt. However, it could use a carb cleaning, but I'd rather do it on a day that it was raining instead of good digging weather. I'll see what I can do.

 

I have to imagine that port needs to be plugged. Why else would it run great and act the way its supposed too? The fact that it didnt really act that much different without any main jet, leads me to believe its not that. It did smoke pretty good though without it

Anyone still running the stock 230 carb and can pull off the carb to airbox elbow to check it out for me?

 

hey just randy got maybe a stupid question for ya got the cases apart on my motor, im now installing everything back together how do the kick starter gears align please...

 

Shove something in the hole and plug it up. As long as it runs right, that's all that matters. I'll see about taking the carb off the bayou tomorrow unless someone else has a 230 carb handy.

 

My manual is due in tomorrow too, so hopefully that will shed some light on this as well. That hole has a brass insert, so I think I'll try soldering it shut.

 

Wait for me to scan the book. There is no way I can explain it.

 

Does the brass insert screw out? If so, that would be an airjet.

 

 

thanks i will try to make sense of that do you guys just need a pic of a stock 230s carb
