rotary and slide carb

[nitrost]

what is the differance between a rotary carb and a slide carb. thanks

 

[beason]

um one slides and one rotates..

slide carb..

roto carb..

notice the top one the fuel inlet adjustment is a sliding bar..
on the bottom its a rotating thing..

ok i got it sorry for a stupid question but just didnt get it

 

[beason]

no stupid questions.. it can be confusing if you havent seen both.. its just two diferent ways it change the size of the fuel inlet.. one slides in and out to change the size, the other rotates to change it.. normaly from what I've seen the roto carb is on the smaller engines..

And the slide carbs are more responsive, and the rotary ones tend to offer a little bit smoother throttle, as opposed to the on/off power that some engines w/ slide carbs have. Which is why many 2WD ST class racers tend to pick rotary carbs.

In most scenarios, most the people I've talked to prefer a slide carb.

Most on-road guys (myself included) prefer the slide because it gives a better response. I'm still an off-road newbie so I have yet to see the full comparison between the two for off-road.

in buggies Don't even think about rotary.....I had an oddball engine and tried it.....SUCKS...maybe it was th emill but I still couldn't get theat thing lean enough to launch off the line like it should have.....and you have to turn you carb to some real funky positions and even then the linkage won't pull right....oh and you need to make a u bend in the linkage to get under the filter.....and all I wanted to do was hear it go boom, it wouldn't get up to speed and stay there....from 1/2 to 3/4 throttle it was nice but everywhere else it was a dog riding a pig....as far as the ST class....I see most of the guys that do well using rotary carbs in their setups....I'm no on road RC guy so I can't say anything about htat stuff.....

For On-road, you're always on and off the throttle since it's all about "throttle control" on the track. You have to sprint to the next corner, hit your marker, setup for the next turn, modlate power to keep the oneway grabing instead of working against you ... yeah, it's never "mash and crash" like in the parking lots.

Short bursts of speed is usually the case for on-roads, much like buggies, so a slide is necessary. A rotary carb is notefficient in doing that. It lags a bit in response.

yep, the lag is why ST guys like it, 2WD on the dirt can be rather hard to controll, but if you have the right tires...it's a hell of a lot easier....I LOVED my proline bowtie and edge tire set-up, it was the best tires I've ever had, and I LOVE my bowtie 40 series, simply amazing on the savage...
