RE: OS GT33 33cc gasser
As sweet as this engine runs and carburates i can forgive the occasional starting backwards.... i honestly think it has to do with all the compression... once you pull the prop thru it will bounce back off the next compression stroke and start backwards.
Being left handed i can stand behind the wing and can get a really good stroke on the prop.... 95% of the time it starts correctly.
When my brother starts it from the front 2 out of three times it will start backwards.
i'm going to let him try the reverse flip tomorrow and see how that works.
