Tank you Bern and Sotxbill for your replies.
I disconnected the air tube at the intake manifiold..
then started the engine and it ran normally.
Removed the oil cup under the air filter it was full of ice
(tractor is always outside). I guess it sniffed fluffy snow on the
hood on warmup at many occasions. In future I will remove the
snow on the hood before starting the engine. In the past I cleaned
up the snow on the tractor during warm-up.
At 75 still learning !
Again thank you both to had take the time to reply
Greatly appreciated.

I do see some oil bath air filters that are in bad need of servicing. Either full of mud, empty or the screen wire full of flax and debris. Have seen some full of mud-dubber nests that stopped it from running at higher speeds.. Newer tractors have the air filter restriction light that helps solve the rare air filter plugging problem. And I see tons and tons of blocked tank screens, fuel filters 25% full of water. Every time you run a tank low, it seems you stir up the gunk on the bottom, including water bubbles trapped there.(more common on the 4 cyl row crops)Thanks again for the feedback.
