Check the hoses on the back of the button, they came off one time and I had an issue with it.

Well with gas in tank, oil in the pan and some luck it should start. Use the starter bulb and try a few different settings on the choke.

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

I bought one of these carbs, bolted it on and it has worked great. Didn't make one adjustment. Sounds to me like you have a issue with fuel maybe getting to the carb. Normally what was thought to be too much fuel ends up being the exact opposite. Try taking the gas cap off and starting the machine. Maybe vapor lock? Check fuel filter if there is one, that it is not clogged. Collapsed fuel line? Is the bowl on the carb full of gas when the machine shuts off? Oh and to answer your question, the screw is most likely a idle air screw that can be adjusted to set idle speeds on the carb.

You did it correctly. Make sure the top button is all the way forward, pressed against the front of the indentation, at which point you will hear gas coming out. Sometimes I have to fiddle with mine a bit, but I've always gotten it to light.

I saw the same problem, and it refuse to light and all i smelled was gas coming out. Wrapped the gap with tin foil; lights on the first press of the piezo electric starter. If I need a better fuel/air ratio, I will poke a hole in the foil.

I have not installed this carburetor as of yet. I bought the euro max carburetor from CIP1 with a new single vacuum advance and it works awesome. No air leaks from worn parts, ect. I bought the Empi carb is for another engine I have but it has not been installed yet.Dave

I sold my unit and bought another brand, so I have nothing to look at to help you. Your best bet might to to find one on display at a store and look at it or check youtube. There are carb rebuild videos on youtube.

Try blasting the pilot light area with compressed air. If that doesn't work would test thermo-coupler. The thermo-coupler is the piece of metal surrounded by ceramic that sticks into the pilot light. Once it heats up it creates a small amount of electricity which hold open the gas safety valve so if the pilot light goes out the gas shuts off. This is why you have to press down on knob to light it you are manually holding open gas safety valve.

I've had no problem with mine at all. This includes all points where the gas line and carburetor might leak. Certainly if you strain the gas line or damage the unit, there may be a problem. I always would suggest that the line is shut off and carburetor drained out by running to minimize any possible leaks and start up problems when the unit is put into storage. the units that were a problem were generally smaller than this one, although I still think 'operator error' may have been a significant part of the problem.

The carb is a rated 3hp to 5hp. If you have a plastic carb with the primer bulb currently on your engine, then it should work.

Ned,I'm no mechanic, but I can tell you what happened to mine. Same problem, very hard to start and then to keep running. In a nutshell, I was using regular gasoline which in a few short months caused an air leak by eating into the seal on the carberator plate cover. You might want to check and see if you have any leakage on the bottom of the carb plate. I replaced the gasket and started using Alcohol free gasoline (which the literature says to use) and have had no futher problems. Starts easy, runs great, without the constant priming. BTW - I found that Dealers will not cover any gasoline areas under warranty. Ned,I'm no mechanic, but I can tell you what happened to mine. Same problem, very hard to start and then to keep running.

deborah, i have the same engine & when i opened the pkg, it was missing a carb. i called the shipper & one was sent that week, no questions asked. if your engine is out of warranty have you tried tightening the housing bolts. if not out of warranty call the shipper & you should get the same service i did, hope this helps,

This carb is equipped with an electric choke. There is a different model number that is a manual choke.

That carb works best on that SBC. However.. The work is in the carb itself. Casting flash inside metering blocks. Verify jet sizes. Secondary blades 1mm open. Not a square. Choke can needs to be shaved down to idle lower then 1,500 to 1600 with initial start to low. Verify float height and double check base for warpage, 0 backlash on accelerator pump arm. Don't assume. Check n verify. Mine runs great after I did all that. Good luck on your project! Larry

Check your fuel line and connection. Carb should not drip, send it back if it does.

need to mix fuel stableizer in with the gas, if not the fuel gums up the carb and it wont start, i always put it in the gas when i buy it,
