Well I was going to send you the links to some topics that 79coyotetrg posted a few months ago.

Looks like that was a topic you started too though.

Got a few tips some people gave there, plus what Glen is running for jets, I think his settup is similar to yours.

No big deal:D  I sorted my problems out last year I thought, kept fouling plugs, decided to go back and do the job right this time. When i searched your old thread was the first thing to come up, then I folowed one of the links in it and got back to my old thread, it is like a big cirlce now. or a square atleast. Best of luck

id be happy to wermz, it may be a week or 2 before the jet kit gets here it was on back order. Ill post when i get the top of the carb off and let yall know what jets are in the carb now. Im going to need help deciding on which jets to install first anyway.

ok just pulled the top of my carb. The stock jets are:  170/140primary     
180/150 secondary.
 
Seems like that should work pretty good with my setup?? It doesnt though Like i said i have the mixture screw turned out about 3.5 4 turns for it to run with best power. I CAN turn the mixture down to about 2.5-3, but it has alot of dead spots and hessitation. So what do yall think i should try out first.
 
Also do you guys usually swap out the idle jets? Another thing, should i put in the double pumper main jet or leave the single pumper in? Thanks
 
EDIT: I just got done putting in 180/150 primary....190/155 secondary 
 
Seems to help a little bit. No drastic changes. Ive got the mixture screw turned out alittle over 2 turns not quite 2 1/4. Also i tuned the idle speed screw exactly how the weber directions said and im idleing at about 500 rpm and its alittle rough. Now im not sure if its the cam im running or if i still need to play with the jets. I think the cam i run has 280 duration and 440 lift something like that.
 
One more thing i just realized. Should i be installing the idle jets that correspond with the other jets in the jet kit along with the new air and main jets i install? For example the corrector jet comes with an idle jet in the same compartment in the jet kit.

I run 145\185 primary and 140\180 secondary.

Anybody have any tips or info on this?

turn the idle speed screw on up to 750 rpm

when  you rejet your carb did you install larger idle jets, or did you leave them alone and install only fuel and air jets?

i only changed the fuel and air jets,  i idled fine so i never messed with the side jets
