I am considering buying an used Suzuki 2HP - The unit is clean, compression is good, but the owner says the "timing needs to be repaired". Is this something a novice (myself) could do with a manual, or do I need to take it to a shop? If it would need to go to a shop, how much do you think it might cost? <$100, >$100?<br />Sorry for not many details on the exact problem with the timing...this is all I have to go on for the moment. The unit is kind of a silver color with blue Suzuki logo and blue decal with white outlined "2" on it. I don't know the age or model number at this time.<br />Thanks,<br />Doyle
