I still can't figure out my rough idle. Everything in the fuel system has been replaced.

Check your 02 sensors, cuz the failure of old injector probably dumped more fuel in system than normal, second if you took your distributor out to do intake, you may have a crank and cam sensor correlation issue, if you cap and rotor had been off the truck during repair check the contacts for corrosion , I left my cap and rotor off for 2 days and the air oxidized the inside cap not allowing proper spark, do not use fuel treatment additives they can cause false readings at the 02 sensor, if you have a code scanner see if you get codes

these model cars are bad about breaking down dist caps and wires.the wire will look good and they will intermittently fire,but run rough.these engines have roller type lifters so you hardly ever loose a cam.

I honestly don't remember. You can try emailing the original seller? It's been we'll over a year and this fuel pump is still going like brand new.

Ask to the vendor if can change it. The problem is with the engine. regards

There two things I would check. First make sure the fuel filter in the tank is hooked up, they have come loose. Second I would check the primer bulb for a hole, sometimes they are tiny and hard to notice. Hope this helps.

I had the same issue, check your fuel pump. My fuel pump housing had a crack in it and was only pushing half the fuel to the motor that was needed. I replaced the pump and it fixed the backfiring.

You must have a bad leak in Your fuel system. Just changing the carb to fuel injection may not fix that.

This is what i did. Just above your spark plug their should be words Model, Type, Code. Write down those numbers. Go to B&S; wedsite and sent them those nunbers and request the "Illustrated Parts Breakdown (IPB)" for that engine. They sent me that file and i downloaded it to a CD. I now can look up any part for my engine. Hope that helps.

Assuming you followed all of the instructions and the previous answer, maybe a small shot of engine starting fluid (ether) will get you going. Don't overdue it. Also, their customer service is great. Give them a call.

if putting fresh premium fuel in doesn't help. it might be a motor problem make sure you are mixing it as it is. viper motors are a throw away motor like most products sold in the usa .rumor in northern wi is that they are having money problems

You may have bad gas. Start with fresh tank and pump out the old stuff. I know if I leave old fuel in over the winter I have the same problem.

I have the same exact problem. Trade Station suggests replacing the motor and if that doesn't work replace the diverted.

We need the entire model, type and code numbers from the block of the engine, plus you need to remove the carburetor and give us the numbers from inside there, then we can look it up for you. Thanks

Prob better to go through your gas first. Sounds like you have a rusty tank tho. It'll def work for your problem

no, I found out that the cause of my problem is the plastic supply line disconencted from the fuel supply connection. good luck

Still can't get the carb to idle well. I moved the needles in as stated. Just runs for about a minute then quits. Must need MORE adjustments to make it work.No luck so far!! Will keep trying but can't adjust an engine that won't run long enough to do so!

If it has sat for a season or longer, likely the fuel needs drained and possibly carburetor needs cleaned. If not, verify that you have quality fuel as some stations occasionally have very low octane. Also I have experienced the fuel line in tank coming disconnected from the carburetor, which starved the engine of any fuel.
