Testing small heads and carbs on JKM bench

[91daytona]

I have an older JKM flowbench that I have listed for sale on this site and I put it on Craigslist recently. A local guy saw the ad on Craigslist and was wondering how it would work on small engines and carbs. It is a JKM 400 and I never really worked with anything that small. L don't want to mislead him so what are your thoughts. Do you think this bench would work for him ok on carbs, racing karts and small pulling tractors? Thanks guys.

well since a carb is tested around 21'' I think it would be ok.

the big FCR carb on a crf450 flows around 235-250 stock so if you can flow a head at 28'' up to (?) CFM that would be your answer

harley carbs flow around low 200's

I dont think there would be an issue

Thanks for the reply. I finally had a chance today to play some with it today and I think it will work fine for him. It has been sitting several years since I built one of Bruce's benches. He wants some growing room and it will flow a little over 400@28. Thanks again.

I had a bench like that and it would not work very well for for low flow of say under 40 or 50 cfm. It worked well otherwise.
