yup those springs are for 510 max they say 550 but they won't do iti'm guessing it's a midwest#8 cam the motor i bought this year had a mw8 and he was running 1.46 springs on it they are good up to 600. also might want to check to see if your fule line is getting heat off something like the exaust or even the bottom hose i have seen that with the line hitting the hose boiling the fuel before it gets to the carb

well that problem is a moot point now as i spun the three middle bearings under the 4 bolt main caps, i am about to give up!
