Does anyone know what the baseline setting are on the LRP Z28R engine carburetor? And how is the jp4 pipe with this engine?
 
Factory settings for the LRP Z28R is, mid range: 2.5 turns and main is 3.5 turns.
 
That is different from the information on the cheat sheet you posted. I thought the z28r is the same as z28 spec 3. Anyway the cooling head says z28r spec 3 . So is this another engine with different settings. Sorry I did not write the correct information the first time. 2nd question is why cant I find this thead under new posts when I come back? Thanks for any help.
 
JP4 is not the best choice but it will run. Jp3 is better, 086 breaths very well on it.

Hmm, I don't recall posting a cheat sheet for the Z28R... ?

For the Z28R Spec 3 nitro engine the factory settings are 3 3/4 turns for both mid and main per the LRP Spec 3 manual.
