Absolutely the second best modification you can do for the money that you can do for your old inline!! The very cheapest thing, is NOT to buy a spring kit at all, but just remove ONE of the stock advance weight springs. Dont worry, the remanining spring will bring it all back down at idle (they are all cammed together). Just make sure every thing is clean and LIGHTLY lubed (dont want to be slingin' oil/grease around under the distributor cap).$9.98 not spent is $9.98 toward somethin' else!!!
