Muhammad Ali is going to clean up his act and take it to Russia with love for all mankind he said yesterday after an affectationate clinch with Antoliy Dobrynin at the Soviet embassy.

He wanted assurances from the ambassador that "they won't drop a satellite on me there," that he would meet Soviet President Leonid Brezhnev and that he would be provided with two sparring partners for exhibitions.

Ali, just back from Bangladesh, said he is going to the Soviet Union to help relations between the U.S. and Russia. At the embassy on 16th Street he said he knews Soviet athletes were well disciplined, then mimicked how he imagined they followed orders by giving mock salutes.

He asked if people in the Soviet Union knew him and was assured that they not only did but were familiar with his opponents.

Asked if he had already begun training for a rematch with Leon Spinks, Ali, who lost his titled, Feb. 15, said he is down to 219 pounds and would be at 210 by the time they fight again "in three or four months." Ali weighed 228 pounds when he lost to Spinks on a split decision.

"I intend to be the champion again before I go to Russia," Ali said. "The experts are going to say, 'What's he doing, weighing only 210 pounds?' I am going to be dancing from Round 1 to Round 15, if I have to. No rope-a-dope defense. I won all the rounds when I danced in my last fight with Spinks. I am going to lighten my weight.

"I couldn't dance at 228 pounds That was what I weighed at fight time, I had to get down from 240 pounds to 224 1/2 the day before the fight. I didn't train right; I didn't take Spinks seriously. I was eating the wrong food - hotel food, I didn't have my cook with me, I gave away the first five rounds.

"Now everybody says I'm old (at 36). Everybody is writing my obit. But I shall shock the world. I will win the title for the third time, then I will retire and say, 'Beat that record."
