I have a K/B engine, at least thats what is says on one side of the case. On the other side is just the number 3.5 in a circle. I did some searching and the closest thing I could find was the carb on the HB .25 engine. In fact, the two carbs look exactly alike.

As Paul Harvey would say, " And now.....the rest of the story." This engine is in a scratch built car that a good friend had built some years ago (I estimate 15). He was an engineer, so there were obvious flaws. I don't like the carb setup; running of the fuel line and throttle control linkage. So, I guess my question is this: Can I put a slide carb on this engine? It would sure make life easier.

I need to get a new carb anyway since the idle set screw on this one is stripped out.

Thanks,
Mike

Edit: The poke at engineers was just for fun. I'm an Electronics Tech/Field Engineer, so the jib was a respectful one.

In the absence of a recommendation, what do I need to look for in replacing the carb? What measurements do I need to know? Can I use just any carb as long as it physically fits?

I'm new to the whole nitro thing, if you can't tell. Any help would be greatly appreciated.

K&B's like the Perry carb & yours sounds like a .21 , Don't know much about R/C cars but I would say any carb that fits the intake would work . A slide valve will probably cost more than the engine is worth. MAX H.

Max, thanks for the info. Not being real experienced with the glow engines, I wasn't sure even how to ask the question.

Looks like the average slide carb for a .21 is about $30. Not bad compared to $120 for an engine.

Thanks again for the info.

You might check the MECOA web site they may have something to help you . I have a K & B 21 rear exhaust with a Perry carb. A lot of engines in the 70's came standard with a Perry. Like I said I don't know much about car engines although I have rebuilt several for our local hobby shop . When you get it going ,drive down & see me , just south on 281 & a little East. Good Luck .

Cheers Max

I just rehab'd an USA-1 Nitro. Put a Dodge Ram body on it to look like its big brother.

This car I'm trying to get running was homebuilt by a good friend that passed away a couple years ago. Kind of an homage.

I'll give ya a hollar when she runnin'.
