Doe's anyone know if you change your clutch spring's Orange /Blue Drive and Black driven, which has raised my engagement by 400 rpm's if this would effect my TPS when I matt it out of the hole causing just a quick backfire thru the air filter? It does not do this at all if I am moving then hit throttle. One of these day's I will be able to repay all of you who have helped, I am learning. Thank's Hoov. I am taking it to have calibrated on Monday anyway.

 

Clutch engaugement will affect load on the engine which will affect whether it needs more fuel or not. More load needs more fuel or more timing.
Two or three ways to go on this. If you can advance the timing this may take the snort out of the air door. Or you can richen up the mix. Or you can put the factory clutch spring back in.

 

that s+cks,i would'nt mine engaging alittle higher,it won't change the tps but,if your not set right maybe it showed up,set it 1/16-1/18 play,check timing,retarded will pop threw carb,set valve lash,plug,raising octane did great things for me.depends on mods thou.

 

i put another spring in mine w/out any throttle issues.
