The Canadian no's are a bit of a secret, as are the European (9's) and Aussie (8's) but I know that Canadian 706.... is 1975 so your 702 is most likely about 1972-3. 4 years is a long time, I hope you put new fresh fuel in her <br />If the last person to run it left old fuel in the carbs, they may be a bit gummed up. Does it have integral fuel pumps on the sides of the carbs or an independent pump ? You might want to check the rubber diaphrams. Sounds like a fuel delivery issue to me.
