Interestingly enough, the best prices I found on the Walbro K10-WAT carby kit was from a R/C model hobby shops. $13.50 AUD from http://www.hobbysupplies.com.au/Zenoah%20Acc..htm $16.50 from powerslideracing.com.au The cheapest price at the mower shop was $22.75 + $5.50 p/h and ranged up to $30.80 and $31 with free postage.
