i thought the u joints were the main reason to get it level. the 292 i set up is 5 deg off level. not ideal but i wasn't going to to the mods to the get it straight. it 2 driveshafts so i hope it will be ok at less than 2 deg each. the carb angle doesn't seem to bother it. it runs well going uphill too so i wasn't worried about that.
