It won't be any easier to pull the start cord, but replace the cord with a stronger one of the same, or slightly larger, thickness. Try your local lawn mower shop better cord.. Also while at the shop, get a better pull handle, like something for a chain saw. 30 to 1 is a standard ratio for most 2-stroke engines and should work just fine. If you want to upgrade, buy synthetic 2-stroke oil. Once again the lawn mower shop will have that also. One last thing, I've got a 36cc chain saw that would be very hard to start except for the compression release valve. These are also available at the local lawn mower shop, if they sell chain saws. http://www.av-v.com/CompressionRelease.htm http://www.fastcushman.com/release_valve.htm http://www.tpeng.com/compression_releases.php http://www.mcadvantages.com/index.cfm?fuseaction=cProducts.view&productid=7686&cids=-1,34,164 BTW the biker folks got the idea from the chain saw folks. However, you must have to have a shop install the valve because it requires tools and skills most people don't usually have.<br><b>References : </b><br> There is probably nothing seriously wrong with your ride except as you said it is cheap.
