carb that fits into the new 15FE engine

[jon2]

I recently git my hands on an OS carb that fits right onto a 15FE engine. I know that the OS10E does work and fit right on but the one I got does too. It is not the 10E carb. It is a 2BK!! wiill try it out tomorrow.Anyone have any knowledge of this carb?

Hey, I am not to sure what size the carb is, but if you put a smaller carb on it will restrict air flow. The engine is meant to have a certain size carb on it. The air intake is meant to allow a certain amount of flow in, the carb only mixes the air and fuel. If you get a bigger carb, it won't make a difference because the carb only lets so much in at a time.
If you want a bigger carb, you would have to adjust the timing on the intake to.

I think this is right. I have been told this.
I do this on the r/c drag race boats I have to.
You have to for them.
If anyone has a different opinion on this, no offence will be taken, just trying to help out. Hope I gave the right info.

I did and got the big bore carb. That didn't help since it doesn't help you out on tuning the mixture needle :tank:
