Re: Hummel 2400 General Discussion

FYI-- I had the opportunity to compare a P tip to my Sensnich. I was told that the P tip was designed to be flexible near the tips so it would un-pitch under load, then re-pitch at cruise rpm. They were both 54 X 44. I ran both props within an hour of each other. At WOT the static rpm with the P tip...

Re: Hummel 2400 General Discussion

Just a side note. Talking about performance, cold air, different carbs, etc. etc. Seems there is no perfect carb. But there does seem to be a viable alternative. I just listened to to Jeff's podcast Episode 58 "SDS EFI for your AeroVee". Ref. http://www.sonexflight.com/58/index.html . Inte...

Re: Hummel 2400 General Discussion

Yes, I have the the fairing around the leg and wheel pants. I have been thinking about fresh cool air if I had an airbox on the firewall and run a scat tub down to the bottom of the cowl for fresh air do you think the low pressure would be a problem pulling in air? HI Densil, I really don't underst...

Re: Hummel 2400 General Discussion

Hi Gordon,
Do you think the 2 inch pitch difference is causing me 400RPM difference? Or would you suspect a timing or fuel delivery issue?

Re: Hummel 2400 General Discussion

I just looked at Gordons numbers. His temps are a lot better than mine wonder if he has the temp located under the plug, which is where mine is. Hi Densil, Yea, Gord lives in Canada. I don't think our northern neighbors worry too much about engine temps. Don't know where he measures CHT. Hard to sa...

My name is Densil Baker and I am located at Pikeville, Ky KPBX. At WOT I am showing 128 indicated I normally cruise at 105 -110 at around 27-2800rpm. I am not 100 percent sure my rpm gauge is accurate. I used the areocarb for first 50 hours and the slide stuck on me down at Tripple Tree so when I go...
