: -------------- I have been surprised at the recent flurry of carb postings.

Keven,

The first 13b rotary powered a/c I was lucky enough to get a ride in

belonged to Ron Gowan from Ft. Worth, Tx in the mid 1990's.......Ron's

Long Eze had a Marvel /Schebler "HA-6" (Horizontal) carb that was used

on the Beechcraft "Musketeer"and perhaps other a/c......I believe Ron

has about 500 hrs of rotary time with that carb.......Ron is the DAR that

just recently signed of Mark Steitle's 20B powered "Lancair ES.......I

do not know what if any mods (Jet changes,etc) that Ron made to the

HA-6........Perhaps if he is listening he will fill us in........FWIW
