I just picked up a nos HR 178 A can anyone tell me if they were all sold as alky carbs . only ones i can find in old catalogs are listed as Hartman alky carbs. it has the lower air filter cup mounting hole machined off like it's for a rotary engine to clear the starter nut. It has a ball check should I change this to a needle and seat. thanks for any help. Jim
sounds like pretty good chance alky carb ..I think a lot of folks ran grose jets mainly in alky carbs ..they work ok I guess ...but man there hard to seal and get accurate pop off,s Lol..

Steve it's not a grose jet. the 178 had a ball check with only one ball from factory or were put in by hartman. Jim
Jim,
I am told it is one of the best alky Tillys to be had.
I think you should sell it to me cheap.
