I agree with Ralphierace13 shimming is a good option and maybe your only one.
IMO the other thing you need to check is the length of the crank. You will need to remove your clutch, take the motor apart remove the crank and measure the crank from end to end, then post that on here and other people with Flash motors can compare it to the length of theres. If the crank is the same length as everyone else then as posted before the bearings may not be seated correctly taking out your room for shimming. Remove them and put them back in. If it turns out the crank is short then the only answer is the one above to make the crank longer by shimming the thrust retainer.
Then if you are still having trouble take the motor back to the distributor and ask them to have a look at it for you . Or did you buy it from the internet and have no backup support. If so like said before take it to your local track and ask the guy with the fastest car to have a look at it for you.
All the best Andrew
