Hi all, I am new so here are some things about me. I have a Rotary brand bike,it has a 30cc 2 stroke motor built into the rear wheel. It is a close copy of the Sachs 30cc. It is a neat setup but it is a rope pull to start,this is bad but it is the only drawback of this model that I can see. I can wind it out to about 40kph,and that is fast enough for me on a bicycle.
I live in a small town where so far I have only spotted 2 other powered bikes,they passed and waved but could not stop to talk.

Anyhow I have a Question, What could cause the petrol mix not to flow when I have a filter in the fuel line?,take the filter out and it runs fine,put it in and fuel problems result.Any help appreciated!

Yes,flushed the tank out and fitted a new filter,checked the fuel lines, all running ok,never struck this problem before. I have owned alot of bikes motor and motored,this is weird,Could it be a head gone,altho it runs ok.

Hi Corgi1, yes washed out the little screen,forgot to mention that,sorry. I think I will email Rotary and ask if there is a special filter,do not know what else to do. Appreciate your thoughts.
