Do you have this problem when engine is cold? When you run the engine cold the cold engine fuel enricher is retracted and you are getting extra fuel thru the enrichment jet. As the engine warms the 6 to 8 volts running to the enrichment acctuator heats the capulary which than allows the needle to expand until it eventually blocks off the enrichment jet. If your fuel enrichment is bad the engine will run fine cold but not when hot do to a very rich mixture. If this describes your problem check the power to the fuel enrichment valve making sure its getting power. When he rolled it it could have loosened a connection. The more specific you are with describing the problem the more accurate we can be which will save time and money from not changing unnessasarry parts or time in your labor. TOM
