Hey all….
got a better test on the stand for the bleed mixture control and things are looking positive. A old magnum 91 was dug out of the engine box and got cleaned and some new bearings and is bone stock except for the ignition and a bleed added to the intake. This one already had a nipple on the intake but it was replaced with a 5mm one which has a 2.5mm bore. The video shows the initial curve which made it work and it’s as expected. The bleed is shut at idle and at top end and mix is by needles there.
I think this might have possibilities as a simple (but maybe a bit less precise) solution to convert glow to gas. More testing planned but it’s up and running faster than most of my conversions.
