RE: GHQ Robotaire
Hmmmm...I was told that the GHQ ran with the needle valve open approximately 5/8 turn and the mixture was 2 to one...most of those old timers ran an 3 to 1. GGEEZER whose post is a few up in this list said he was putting his GHQ bacl tpgether and said he had a set of the origihnal instructions.....perhaps he will look on the instruction sheet and tell us if the fuel mixture is listed there....

P.S. that ixture was two to one or three toone using SAE70 and gasoline....I have heard that FAI glow fuel runs pretty good on an ingntion using spark, but have never tried it.
