I'd say you need to get info on the cam, it might need 1200 to idle depending on its timing characteristics. If you can't get published data then you'll have to go through the drill with a degree wheel, piston stop, a good dial gauge, and friend who will wrench the engine around for beer.

The wilder the cam the harder it will be to tune, as someone said you need a timing light if price is a problem look at Harbor Freight, it's Chinese but at least you pay for made in China unlike so many American brands that are also made in China but charge you made in America prices.
