Mixture Mayhem

Hey, does anyone know how to set a proper mixture on the stock hitachi carb? I can't seem to get it right. I think I fried my last catalytic converter because my mixture was too rich. I know that screw in = lean and screw out = rich. If only my sammy was set up like an airplane... then setting the mixture would be a snap. Unfortunately I'm lost without an EGT and the ol' drop in RPM's method doesn't work either. Could someone enlighten me? Thanks.

Re: Mixture Mayhem

without a mixture sniffer I think its impossible. That said someone please correct me. The adjustment is only for
idle, the active carb adjusts the mix otherwise from off idle on up. Sorry I'm not of more help. I don't think anyone
is really an expert on these darn things. I have the shop manual and have been trying to get a full grasp on this thing
since feb. I have everything working great on mine except an inconsistant Idle. But I also have a hawk cam in the
engine and am more and more convinced that is alot of my problem.

Re: Mixture Mayhem

Grasshoppa- Calmini sells a lean/rich indicator. Don't know if that will help you or not. How did you remove the pin blocking the adjustment screw? I used a hammer and chisel to remove mine, then the carb ended up crapping out. I bought a reman carb(BIG MISTAKE)and the pin was removed for adjustment.

Re: Mixture Mayhem

It looks like the previous owner did somehing of the same with my carb. Somehow they broke away some of the area around the screw. I don't know if that's why my carb is so erratic or not but I do know that I don't like the hitachi carb. It seems to have a mind (and attitude) of it's own.I end up messing around with it almost every week trying to get the idle to where it should be. I wish that I had EFI so that I wouldn't have to mess with it anymore. By the way thanks for the lead on the indicator. I'll check it out.
