hi all. just did the head gasket on my 22r. it ran perfectly on startup. when i took it for a spin and it kicked off hig idle and started to idle rough. almost like its running on three cylinders. accelerates smoothly but sluggishly in low rpms. but pulls fine at higher rpms. and backfires on decel. please help.

 

timing chain off a tooth

 

or fuel mix too rich at idle
or valve adjustment required
or ignition timing not set correctly

 

thanks for your help guys. i just figured it out tonight. distributor was off a tooth. duh.

 

yup... that'll do it.

my buddy's elcamino was a bit trickier. I found the right tooth, but it didn't line up with the oil pump. so i made it fit.

 

Rebuild my 22re ran great!! Electric fan quit and got a bit warm. now after warm up it runs sluggish like out of time? Checked and all is well there. Im stumped. any ideas??
