Carburator Tuning
Posted: Sun Jul 25, 2004 6:41 pm
Hi,
I have a new engine installed and fitted the 40 DCOE 32 which cam with the engine, it is a big-valve with C-type cam and 43 D 4.
The carburator is main 120, air 170, pump 45, F 11, 50 F9., choke 32, K+ N,
It runs at idle but if one give throttle it roarssss and then it goes up. have fitted 45 F9, 50 F8, less and more than 10-12 ignition, but can?t sort it out where the mistake is. Use Shell 100 oktan, after 3000 it goes like turbo charged.
Any idea, never have had this problen on many engines of mine, what did I make wrong?
Thanks
