Hey guys, it's been a while since ive last signed on. But yea my 14' is running really rich. Last week when i pulled the spark plugs for a change out the old ones were entirely black. That would signify that my engine is running rich, right? The engine is a 75' 2L w/ stock Djet FI w/ the smog stuff plugged up. So what could be causing my engine to run rich? Bad MPS? Bad throttle body? If so either one of these things ive got a stock 1.7L dizzy i'd like to trade someone for a replacement part. Or possibly something is adjusted correctly. Thanks again in advance!

first check out the CHT as that could be bad causing richness
then check out the MPS by putting a vacuum of 15hg on it as it should hold it for bout 5 minutes. or your flux capacitor is modulating wrong so add less fuel via the thingie. (IMG:style_emoticons/default/biggrin.gif) |

(IMG:style_emoticons/default/biggrin.gif) The CHT, is it that doohicky located next to the dizzy w/ one wire coming out of it? How do i check to see if the CHT is bad? As for the MPS how do i go about putting a vacuum on the unit? Thanks Bleyseng (IMG:style_emoticons/default/smile.gif) |
