Sometimes there is a adjustment screw that you can turn just like a car.CAREFUL NOT TO TURN TO burn lean or rich.also you might want to change the fuel and air filter's first,then try to adjust.

02 bmw 325i misfire cold start

plugs and wires. yes wires are the biggest issue with a misfiring engine. check the gap on the plugs. sometimes they are gapped to far and cause a cold misfire issue. simply pulling plugs and look at color of the insulator will tell the condition of the engine. normal should be a golden tan color darker means its to rich or burns oil white ask means to hot and should use a colder plug

Have a farmall super m need gap measurement on the points

The point gap should be 0.013 inches. You should also check the end play and run out on the shaft before point installation (vertical & horizontal movement)- should be minimal or the engine will run erratic or not at all if too loose.

Timing is off,problem with timing chain,also check fluids in ******,plus also if you have a distributer in your vehicle,if it is cracked,moisture getting in and ruining the points,-that is if your vehicle has a distributer! This will make a vehicle run rough as well.
You can have new plugs put in,but if your spark plug wires are cracked or worn,this will also creat misfire and backfiring.

Engine Performance problem 1997 Chevy S-10 4

According to my book, the first code is the brake control rough road sensor, and P0302 is a cyllinder #2 misfire. Check the gap on your plug, and make sure the plug wire is on all the way. Give the boot an extra good push. Backfiring or misfiring under load is always caused by poor ignition. You may also have a faulty plug or wire.

For a carbureted engine, backfires can be caused by the valve train timing being way out.
Set your timing properly first, and then move forward from there.
Blackened plugs definitely mean too rich a mixture, and maybe not enough spark to burn it all.
I've never seen a bad vacuum hose cause backfiring, but it will help very much to fix any vacuum leaks you can find.
