Can you get bigger ones than this ?

Yes you can get bigger, 46mm, AMR Manufacturing make one suitable. The one I use requires a slight remachine and a notch filed in the side to clear the cruise control bracket.

However of more concern in your pic is what appears to be the gas inlet hose, with a brass elbow in it??? This may be the root cause of your problem, not allowing enough gas to flow for full power. There should be a smooth bend in the gas hose to connect directly to the inlet. A hose with a bend at one end is a standard lpg part, available from most wholesalers.

That elbow goes into the large rubber inlet pipe about 10cm before the actual plenum.

Is that the gas feed ?

Well I am not there to see closer, but if this hose comes from the gas converter then its probably the gas feed hose. Just I can't see any other hose big enough at the mixer. Oh, and your picture isn't all that clear so its a best guess.

I'll post a better picture with it all set up. That pipe doesn't go to the gas converter. It loops in to the main air intake pipe

Here's a better picture with everything in place.

The arrow shows where that brass elbow is connected.
