Hi i meant to ask if you are running on board glow at low idle speeds,i like the continental style shape of the heads on the 90ts a friend has one unrun yet to go in a small falke motorglider,very graceful aeroplane re aerobatics.The pipes you salvaged from a 100? to fit the 90 cracked me up,who's on drugs now?
ps while i'm at it i should apologize to the good people reading this thread for popey's genteel,anti shooting manner.The poor so and so lives in a redneck free southern state over here,how's that for being round the other side of the world geography wise,it's upside down i reckon
