RE: DL-50 engine
Hi Bob,
I tried to PM you, but I don’t think it went through, as I do not see it in my inbox sent folder.
Anyway I have been to your website and read the Walbro tuning guide, I do not mind setting the needle leaver even if it's by trial and error. I do not have a " setting gage ". I'm very mechanically inclined and should have no problem with this. Any words of wisdom before I attempt this would be appreciated.
Thanks
Geppino

Now let's check out the "float needle & seat" setting.
This is the single most critical setting on a Walbro carb! Walbro offers a "setting gauge" to properly set the height of the lever for your particular carb. If you don't have one, the setting will be a trial & error adjustment and a real pain in the butt since you have to open up the carb to make the adjustment. For general purposes, the lever will be almost perfectly parallel to the carb base. This will get you close. If the lever is too high, your engine will tend to run a little erratic at idle. If the lever is too low, your idle will be OK but it will tend to run lean on midrange and highend. It may also run the float cavity "dry" at full throttle and die, regardless of your highspeed /lowspeed needle settings.
The needle valve seat is pressed into the carb base, and you should not remove this without having the correct tools and setting gauges. Do not remove it!
