Default Help with an old ASP 75A
Hello,

I've got an ASP 75 i've been trying to tune in on my test stand. It has a carb I am not familiar with. Seems like its got two needle valves. I am assuming the extra one is for the low end. Trouble is, I don't have the factory manual for this engine and can't seem to find the right combination to get it full power/then idle with good transition. Anyone have experience with this engine? Anyone able to quote me the settings from thier ASP manual? Or other good trial and error plan you engine experts can divulge?

Horizon hobby sez this engine is discontinued and no PDF manual is available on the internet.

Thanks
