Allis WC cranks a lot b4 starting?

I have an Allis WC 1941 6v pos. ground distributor that cranks a long time b4 starting. It does start and run good once it starts. Good spark, clean carb. and good strong 6v batt. Was wondering if there is a common carb adjust or some other trick to fire her quicker? Seems like not getting the fuel quick enough, but once she is running runs great. Thanks for any advice, Jeff
 
Hold your hand over the throat of the carburetor to see if there's much suction on your hand. You will need a helper to try to start the engine. Low suction means low intake manifold vacuum. Could be a vacuum leak or worn engine parts. You can do a compression check and compare the readings. Your starter may be drawing too much amperage dropping the battery voltage if you have a distributor. If you have a magneto make sure the impulse coupling is snapping. That give's you a hotter spark during cranking. Hal
 
(quoted from post at 08:52:15 01/06/12) Is the choke working? Going all the way shut?

ill it start easy if say you run it and shut down then restart?

If you have really good spark, bright blue that will jump 3/16 or an inch you can eliminate spark except where you may have voltage drop due to starter draw. So take an old plug and spread the gap and have someone crank it while you check. Also check timing. If it's good while cranking then move on to fuel, vacuum or compression. As you were told check to make sure the choke is fully closing. If your engine is worn the long crank could be low compression. As you crank it's getting oil on the cylinders and that will increase the compression. If you don't have access to a compression testor you can pull the plugs and put about a teaspoon of oil in each cylinder, replace the plugs and try it. If it fires right away you have a compression issue with the rings. If it's a valve problem it will not help.

My 230 Farmall started doing the same thing - sometimes wouldn"t start at all. After reading about a similar problem on this form, I tried the crank instead of the starter and it started right up. Starter taking to much draw. If you crank be careful to just pull straignt up - don"t spin - dad got his arm broken that way when it kicked back. Could also try pulling - if it starts right away it could be the starter.

Hal JFYI it is easy to stand next to a WC and both hold your hand over the carb and crank it over at the same time. I start my W Speed Patrol from the side all the time and it is almost the same machine just longer and has the blade under it. I do agree with what you say other wise and that is a good starting point as to what might be wrong
 
If all else fails, try playing with throttle setting. Each engine has its own sweet spot.
I have a CA. Fires on first turn with throttle on third notch, no choke. In cold weather have to play with choke AFTER it fires until it warms up a bit, 30-40 seconds. Warm start it will fire at any setting, but cold weather it won't even cough at any other setting. Just had to learn its habits.

Do you use the choke?

You need to "feel out" what your tractor needs. Most just need a quick blip of choke, some need the choke set full on until the engine fires, some need no choke at all.

Unfortunately I am not aware of the secret recipe to tune up a tractor so it will fire first time every time with no choke... I have tractors that run like that, but it was just luck of the draw.
