Easy , but you need the carb and linkages and throttle rods ( and throttle cable) from a auto DG

Only considering it at the mo. Nowt is written in stone as yet.It does make me wonder why most ditch the injection system for a carb.

because they don't understand injection and a full set of spares is more than a carb.
Carb is simple and works but injection is more refined imo
no difference hot or cold with inje tion un like carbs.

I changed because the injection was requiring new injectors and unreliable electrically , and as I run on lpg 99.9% of the time, pointless hassle .
I’ve not had more than £50 of petrol through this van in 7 years and 100,000 miles. Never start on petrol, only ever run on it once a month for a mile just to be sure it can . Have you seen the bloody price of that stuff, it’s over a quid a litre.......

Carb/s is where I plan to go if the injection set up on my 2.1 WBX suffered a catastrophic disaster or just got unreliable. But bearing in mind that it is circa thirty years old and on a par with 405 line black and white TV and trouser turn ups in terms of technology, I can't believe how reliable it has been for over ten years for me.
Got to admit though I do miss the sheer balls out acceleration and valve bouncing revs of a big carb. :wink:

You run on LPG, Rob. Whether you're on carb or injection, the only bit doing anything is the throttle butterfly! Waste of time/money changing.
One other difference is heated manifold on carb, not on injection, so power is lower with a carb set up (you want your air/fuel charge to be as cool as possible to get more in per stroke.)

yes except you want the petrol to work if you run out of gas, or at least most of us do so the injection system needs to work, if it doesn't I can understand the change to carb.

Andrew should us LPG on carb users bypass the water heating through the inlet manifold?

Electric heater is thermostated so not really a issue I'd think

No, because your auto choke won't come fully off if not water heated. And it'd run rubbish on petrol.
