Sorry it is an aero sprint cat will try to send pics is there anyplace in Canada that can rebuild a QD thought a stock 360 pun would be more reliable and easier for a new be to run

QD is in US but they do rebuilds for Canucks all the time give them a call

Most of the time a rebuild is cheaper than a new Zen - and will out perform a stock Zenoah pretty easy
Call em see what they say

bought the boat used had the walbro257 rebuilt. have the carb set close to what is recommended. using 2716 props, runs great in the driveway but having a hard time getting it to run under load you get a lag and it stalls How do you guys make adjustments for this without it being stuck out in the pond.Have been trying for 2 summers and had it running for a while but no where near as good as it should be. so i thought a new motor might have been the answer. I have run E/L boats for a bout 5 yrears and this is the first gas. If you can offer any advice it would be a great help

That looks like a 644 cover plate on it if that's a 257 ? 257 has a flat plate on top

Maybe carb is mixed and matched but doesn't look like normal 257

Good eye Randy! Walbro's primered carb doesn't have the smooth bore like that one does. The previous owner may have put it on himself. Most people don't use those carb's although they are good as most find that all you have to do is place a finger or thumb over the opening to draw fuel in the pull it over slowly until your digit is wet.
