I have replaced the plugs, wires and cap. set the mixture screws at about 1 1/2 to 1 1/4 screwed out. again, it seeems to be running fine, but the exhaust is EXTREMELY STRONG. it actually sticks to you if you get in it, and you smell it all day. WHAT CAN I CHECK/CHANGE OUT/REPLACE/READJUST? its giving me a headache! thanks for your help friends... tim

We prefer that you post a topic once, on the correct forum. Since you have this on the "Fuel and Ignition" forum, and you have a response there, let's close this one.
