First,take the carb off and see if it has a pulse hole in the cylinder.
If not,youll have to drill a hole on a flat spot under the carb intake.
You use a drill bit the same size as 1/8th inch copper tubing.Then you put a nipple in there with JB weld or tap and thread it and put a threaded nipple in it.
Then you use a standard walbro pump carb and run a hose from that nipple to a nipple on the pump side of carb on the cover.
Ill see if i can find and post a pic.
If your engine has a pulse hole just use the same intake manifold if possible,or youll have to make a new manifold out of G10.
