yeah your right i can hear it. it is really hot i dont have to touch it. what i dont understand is that i have it set very rich. do i have an air leak?
It's very possible. Believe it or not I just had the exact same thing happen on my SH .28. I was sure I had it running rich enough due mainly to the fact the HSN was about as far out as I could go with it still being able to run. I never thought my LSN would be in the equation. Well I ripped everything apart and sealed it as well as switched to a colder plug, still made no difference. So finally I backed both needles out flush and tuned from there. The LSN was my problem. I guess I had it too lean and was compensating with the HSN. I never thought the LSN could effect my temp but after turning it out and re-tuning, my heat problem went away.
