My friend has a 4010 LP Standard that is having an issure. Sometimes it will pop right off and other times it won't start at all. I have checked all electrical connections, replaced the cap, rotor, points, and condensor. It's full of propane as I have loosened connections and made sure it has propane all the way to the converter. I'm just wondering if there is something simple I need to do or should check out. Thanks for the help fellas!

You might check the oil level in the air cleaner bowl. Have you considered changing points/cond to electronic ignition??

I had a 4020 LP and spent a lot of time and money trying to get
reliable operation out of it and it just didn't happen. Every day,
every hour, different time of day, different engine temp, all were
a variance in getting it to light off.

However, in support of your suggestion, I did get CD ign. for
mine and it helped a lot.

Oh, and that was the same tractor that I bought that had these
little holes down the side of the block with oil oozing
out......HA!....another cost of an education........during the
overhaul I realized that it was a premature failure caused by the
previous mechanic (who-whatever that was) put the wrong color
sleeve seal against the fluid to be sealed; had them backwards.

Selling that sucker and buying a diesel was one of the best
things I ever did.

Toby,
Are you starting on Vapor? not liquid! An old Trick used to start 4010 & 4020 LPs is to rotate the steering wheel about 1/3 turn back and forth in rapid succession. it seems to drop the pressure that is generated in the front pump and helps starting. Why, It just seems to start better. At times My LPs will start in 3 to 5 revolutions other times 6 to 10 I know there is nothing wrong. I think it has to do with ambient outside air temps. there are times LP just will start better than others. Hope this helps.
Later,
John A.

The key to getting an LP to start is a hot spark. Close the throttle almost all of the way when cranking.

If your converter is in poor condition it can cause poor starting also.

An LP fuel system in good condition is very similar to fuel injection. It starts and runs good regardless of how hot or cold it is.

Friend"s 4020 has a hole in the center of the regulator where you can use a small nail or screwdriver and it acts like a primer bulb. You can hear it hiss. Seemed to help starting. Key had to be on or no hiss.

If it starts right up when cold or for the first time that day, and harder to start after that the same day its your hydralic presure, try turnning steering wheel or moving hydralic lever when its hard to start should start right up.

If hyd's is causing engine to crank slowly you could install and use a destroking screw(parts key #6).

PERTRONIX INGNITION AND A 2 12V BATTERIES. My 70 LP 4020 fired up like my fuel injected truck after this. Also, after you turn on key and the VAPOR ONLY, give it 5-10 seconds for the vapor to reach the carb
