There are a LOT of good tech articles on the site....just have to look for them!

Not a bad article.Easy if you follow your engine manuals recomendations for your top end and bottom end fuel screws.Great.Start the motor somtimes choke is necessary for a cold start and adjust the idle screw until the motor idles without engine failure.Then you will have factory standard settings according to the engine manual which will tell you a variety of other useful tips.

Most factory carb settings are hot rod.They feel like a lick with the screw driver.1 and a 1/2 turns vertical for your low end.An 1/8 to 1/4 richer for your top end than 1 and 1/2.Like taking some illegal drug screw the idle in full and turn it back a tiny tad until it feel like you have had level sex with the screwdriver.Then leave it up to poor owner to spend hours trying to get his boat tuned.These blokes that put things together for are pretty slick.It feels like your hands had the cane you should try it.

Hi there I'm having trouble getting the needle and seat settings correct for my 771 walbro any tips?By the way its on a sikk.
Cheers Alby

I have a sikk 27.2 with the 771 and i use 1 1/8H and 1 1/2L and go from there.

Hi again I actually need the setting of the needle and seat gap (just below the metering diaphram).It's a real pain,Just finished building a prowler and it fly's with the sikk, when its operating alright.I also have a Zen 26pum with a big bore kit that I might put into it!!!and test the glue.
Cheers Alby.
ps. have also built the 72 inch deep vee from the plans on here,might put the Zenoah in that.
