Marvel Schebler (Facet) Part numbers for Nozzle Jet??
I'm drilling out the main jet on my carb because my engine is running too lean. I have a Marvel Schebler MA-4SPA Part # 10-5217 on an O-320E2D. I need to know the part numbers for the nozzle gasket which goes at the base of the nozzle and the jet tabbed lock washer that holds the nozzle in place after its tightened down. I've searched everywhere for the information on line but I've had no success finding the part numbers. Aircraft Spruce has parts but under the Tempest Volare carb section but the descriptions are not good enough to know what to order. Does anyone who has drilled their main jet on the same part number carb either know where I can find the information or happen to remember what they ordered? Also, did you get them from Aircraft Spruce? Any help would be appreciated. Thanks
On my RV7 A I have Lycoming O 320 A2B original was 150 hp but now 160 hp.
My EGT are high around 1400 but my number 3 around 1500!!!
CHT around 360 to 400
So on my case the ram air effect lean to much and my jet is maybe to small.
Wich one you used?
