Yes that is correct! so my brother and I restored a 1958 420u recently and all it would do was back fire through the carb not running at all. So we did some research and yes the oil pump needed to be turned 180 degrees. Same with the 420c I just got obviously posted above, however it would run on on...

ok Thanks a lot for your patience with me !!!!!

Got it thanks!!!!!!!!!!

definitely is the wrong cap!!! you can order the correct one directly from Lavoy, owner of tis site and basically all parts needed...

i too had run into same problem, get correct cap and problem solved.

The cap I have is the right cap. I have it running great on the cap it has.

I didnt see any free downloads it says I have to pay for them. I am sorry if I am overlooking something....

Thanks a lot that is exactly what I need to know! I cant find a free crawler manual so that is great info!!!

E.Huffman, Glad you found the cause. I went for the cap as I have been given the wrong cap before. Some parts books list the Waterloo cap as a 12 volt cap and the Dubuque cap as 6 volt. The parts person asks 6 or 12 volt and if a conversion to 12 volts was done, the answer is 12 volts. Reality is t...

So It looked like it had head work done within the last 5 years but I had no idea what, the man that owned it had a brain injury and his wife was just trying to get rid of it. So when we were messing with the spark plugs we happened to look into the block and judging by the way the side wall looks i...

Honestly I just bought it 2 days ago has'nt run right since I got it, how ever we turned the oil pump timeing 180 degrees and works beautiful! Thanks alot!

so I have the one that has terminals on each side of 1 clip like the right one you were describing. So we even took the whole distributer assembly off our john deere 40 wheel tractor (it has the same dist) and still only one cylinder. It has become quit a frustrating problem!

Ok well if it doesent care about voltage then I am stumped because thats what i HAVE.............

I do believe this might be my issues! I have a 12 volt system with a "6 volt" cap!

So i have a newer (1958 or newer) 420c that i am having issues with running on one cylinder. the plugs,wires and cap/points are all good. however when we rotate the whole distributer 180 degrees it switches from the front to the back cylinder still running on one cylinder and vice versa when switche...

Hi I just bought a late model (58 or newer) the reverser is on the left hand side. However I am wanting to change the oil in it I think i found the plug on the bottom but how full do i fill it and where do i fill it?
