You have to buy direct.

The dollar is taking a beating right now against the Euro, 1.00 euro=$.75. Use a web translator to read the pages, a online length and weight conversion to convert measurements to inches and ounces and a online currency converter to do the price.

I would go with a hopped up, CH ignition, 29cc, 3.5hp, G-26 clone. Do a search here for a Canaday 29cc engine in Arf's and gas engines. $399.00.

Some of the parts to make your own 29cc are here:
