running lean and "gassy" exhaust smell?
So how normal is this for a pre-emissions control engine (1296 with Stromberg CD150 no emissions stuff at all)
After a drive, my spark plugs are nice and clean, no signs of oil / carbon deposits, (actually a bit orange colored!) If I lean out the engine any more, I have drivability problems.
But the exhaust still smells like I am spraying gasoline...
now to get avoid being super rich I had to adjust the fuel float level about 2mm lower than normal, when I had the height set according to the manual the mixture was very rich no matter how I set the jet. I checked the weight of 3 different floats I have and they were all identical so I don't think that the float has a leak???
