I have a Blata 39cc engine that I'd like to use in my next boat, who sells an adapter manifold to mount up a Walbro rather than the Dellorto that it comes with stock?

Scott might be able to answer this for you. He is on vacation right now and should be back in about a week. Sorry I can't help you, I have no experience with these engines.

Is Scott back yet? Any other suggestions? I checked the MHZ site but they only show it included with their Blata engine assembly, not sererate.

I'm back.

Best solution is to have a machine shop, or some one you may know with both a lathe and milling machine build a simple adapter.

Simple male spigot that fits the manifold having a flat face that has bolt pattern for a pumper carb. Run external pulse from crankcase to carb.

** Do some search's on POCKET BIKE sites, have seen adapters before when I had searched on line.

pocketbikesunlimited.com sell a carb kit that come with everything you need. and the carb is a large butterfly style, walbro. for $122
