Is there a trick to hand starting a 1941 AW??

Just picked up my first Waterloo machine with handstart. (Those things will make one appreciate the battery and starter on a Dubuque.) On the flywheel it has LH impluse and LH exhaust. Is there a particular place these marks are suppose to be so it'll start without one wearing themselves out?

I appreciate the responses. I've sent off for info on a super spark mag. Will try all the suggestions this weekend....work gets in the way all to often.

CJDAve.....you were a busy little guy firing that AW. I can picture every move you described. Wish you still had that AW?

Yes, I wish I had that AW. When we traded for a new IH B-275, the dealer didn't even bother to take the AW until MONTHS later and then it was just tossed into the dealer bone yard. The BIG PROBLEM with the AW was the rear tires....9.00 X 40 and we could not find replacements anywhere! It was a huge problem for us, being out on the west coast and all. I also wish I still had my VAI Case that pulled my hay baler as I baled my way thru college. The Case went under a home made backhoe and then eventually on to the Valhalla of tractordom.

Having grown up with a tractor the same model and year as yours I have this to offer: Don't get excited till you've rolled it through the first compression strokes since it will have stopped somewhere in that area when it was shut off. Then when you pass that point you can choke the heck out of it and pull through the two intake strokes..... then up on compression.....one mag click and you are running. I had a routine....I was too small to reach the throttle from the ground so I went up the back.....broke the throttle off the bottom....just a bit...wiggled the shifter to be sure it was in the middle....even swung the hi-lo to the middle JUST TO BE SURE....then made sure the clutch was snapped out....then down and around the right side to open the petcock....then up on the front axle to slip the can off the exhaust pipe....then put the can on top of the breather for storage....then open LH petcock....then begin my start sequence. I survived childhood on all hand crank JD's by using that unbroken routine.

Dear B, as far as starting, theres no particular place to try and worry where those marks are to make her start any easier etc., HOWEVER, they are timing locators for setting the initial dynamic start timing, with the fine tunign start timing then accomplished by rotating the mag CW to retard or CCW to advance.

When the left hand impulse is at 3 o clock in line with the mark on the tractors side and the left no. 1 cyl is at TDC on its power stroke, the mag should just then snap over to fire its plug. If she tends to kick back when you attempt to hand start it, retard the mags timing.

As far as the best method of throttle and choke etc etc to start it, that depends on teh tractor and temp and timing etc etc and there are about as many ways as people on here to advise on that. Many of mine when cold like the throttle open above idle, choke full for ONLY 1 or 2 piston overs, then choke to 7/8. If she floods like youre getting way too much raw fuel out the petcocks, open the choke and throttle both to clear her out.

Good Luck, God Bless and post back any more questions. Ol John T Nordhoff in Indiana

I usually set my throttle so that the throttle shaft arm on top of the carb just contacts the small spring that sticks up. choke it a couple of times, take the choke off and roll the flywheel over slowly. All choke levers on the carb will have an indexed line on the lever that will show you how you have the choke butterfly positioned. Good luck.

BMeyer, you want to hear the mag snap as the L/H impulse lines up with the case mark [at 3 o'clock behind the flywheel]. If it is snapping at or close to the L/H impulse lining up you will have to try different starting techniques.

~Try with different choke positions, different throttle settings & different amounts of each while trying to start. All those old hand starts seem to be a little different & require different starting procedures to get them started. Don't fight with the flywheel, all you have to do is get it over TDC, the mag impulse will do the rest. Most that I have like almost NO throttle to start & full choke for a revolution or two then a little less choke for each additional turn of the flywheel after that. Once raw gasoline comes out the petcocks open the choke wide open & go to full throttle until it either starts or clears.

~Make sure you have fresh gasoline in it, good cold compression, & a good BLUE spark that will jump a 3/16" gap repeatedly.

~Give it a little time & try different starting settings & you will have it figured out in no time..... .
