I've already cleared out a place for it to live. It will be really happy here, with all of the other hardworking machines and lazy animals.

I am interested in the pull-choke Pulsa jet. What is the diaphram carb with the plastic cover? Bottom, left corner in 0027 No pay pal?

I just ignore the spam new members every morning. Every Sunday, I unignore everybody in my "ignoring" list and I never seen them.

That brass tube in the center of the venturi is called the emulsion tube. It is held in by the main jet. Drilling the jet will allow more fuel. Drilling the emulsion tube is not a good idea. When you see how tiny the hole in the jet is, you'll understand. The emulsion tube mixes air with the...

Post a picture. Does it have the gas tank bolted under the carburetor? Is there anything interesting on the bracket under the gas tank?

If you do not hold the intake valve open, does it open itself to let air and fuel in? I think it should. Like I said before, we stuck a rag in the intake and spun it. I do not recall ever touching the valves while starting the beast.

When it ran with the Flo jet carb on it, was there any type of throttle response? With a low compression engine and those huge flywheels, it would seem like you would either flood it or just bog really bad when you opened the throttle.

Maybe try sitting the engine in the frame before you modify anything? I had a totally stock 420 on a mini bike for about a week. That was one day to try riding it, three days for my buddies to try , two days to remove it and on the last day, we rested. You might decide a stock 301 is perfect.

Yes, jets are readily available. A larger jet would allow more fuel in. Have you ever looked into finding an original type mixer?

Stock carbs are great. They are already sized and fitted to the engine. I don't understand the reasoning behind putting a motorcycle carb on a lawnmower engine. I guess I'm just getting old and cheap. I like my engines to start, run reliably and require zero tuning. Now, I will tweak some...

Looking good! glad you won that battle. It is too early in the year to be low on cuss words. Can your bank be recharged by going to Church on Sunday?

@Ranchand60 , in your other thread, looking for the race exhaust, another member offered several for sale. I bought one from him and I do believe it is exactly what you are looking for. Send a PM to @sonerenos

@Geo46 , does it act any differently if you do not hold the intake valve open when you spin the flywheel?

They only have compression sometimes, otherwise, they freewheel with their huge flywheels. If it holds the intake valve open as it freewheels, it would be huffing air in and out of the carburetor.

Does it have a scrub brake? Use your ruler again. Measure from the axle hole to the scrub brake. That is the radius or the tire. Multiply that by two. That will be the diameter, or height of the tallest tire you can run. Wheel rim diameter really does not matter. It is the TIRE height that you...

@Geo46 made a reference to "holding the valve open". I'm not sure what he meant, but that didn't sound correct to me.

We had one for pumping water a LOOONG time ago. It did not have a carburetor on it. It had a mixer that was like a straw in the intake that drew white gas from a little cup. In order to start it, we made sure the coil was disconnected. We took a rag soaked, dripping, with gas, and pushed it into...

Here's another option for hydraulic removal. Install a grease fitting somewhere and pump it full. It might swell the outer sleeve and it WILL definitely force lube into the joint. Turn the entire fork into a hydraulic cylinder. (You're going to clean it out, anyway, right?)

If you are not detonating now, why mess with methanol? After you figure out how to cool the intake charge, your cylinder pressure will increase drastically, producing more torque. That might require more octane, but it doesn't sound like more octane (meth) would help you now. Water injection...

Northern Tool and Equipment sells good steel wheels with stud treads tires, with and without sprocket. They list 4, 5 and 6 inch
