I was able to get Superior on the phone this morning and confirm that

there is indeed an interference problem between the MA-4-5 carburetor

and Van's cowls.  They're accepting full responsibility and will be

shipping me a new Precision carb that is 1-1/2" shorter than the MA-4-5.

That should make the first engine run a little more interesting.

Daniel - now I am confused! From what you say you are building an RV9A with an O-320 and the Marvel is the standard unit as VANS would ship only you got it from Superior. So why does that not work since it does work for VANS? I thought I had understood this! 

  

 Thanks, Steve.

I think I saw yesterday that Precision Airmotive used to be Marvel.  It

looks like Superior originally supplied me with a Precision MA-4-5 and

are going to replace it with a Precision MA-4-SPA which is 1-1/2"

shorter.  I don't know the model carb that you would normally get from

Vans.

Daniel, 

 I may be incorrect, but I thought the  MA-4-5 (deeper) is for O-360 engines, whereas the MA-4 (shallower) is  for the O-320 engines? That's why  Vans makes different depth cowlings (320 vs. 360), but that also makes and  engine swap to 180hp difficult if you were to have started with the cowling  for the O-320. If it were me I'd use the bigger cowling from the getgo  regardless of engine choosen. Like  I said, I may be totally off the deep end here, so please do not  archive.

Daniel - I have a new Aerosport power XP O-320 and looged at the carb. Yes, it is the MA4SPA that you mentioned. I think that is the normal one yo uwill be pleased to know. Cheers, Steve.
