I have just become the new owner of an LPG conversion kit which I have managed to fit to the hybrid this weekend, was one of those jobs that I thought would take for ever, but took less than 6 hours from start to finish!
The engine is a RR 3.5V8 Carb, high compression engine and the kit came from a 110 3.5 V8 low compression engine. I have some gas in the tank, and the engine appears to idle and rev okay and changes over from petrol to LPG and back again fine, but I have not yet taken it down the road to test it, as the old dears came round just I was getting ready to go fill up...
I cannot find any clues as to its make as it was on the donor vehicle when the previous owner bought it, and he has now put in a 300 tdi. Fortunately I did assist with removing it so I knew how it went together, and managed to get the carb elbows too.
I have a large screw on the Y piece on the pipes running from the vapouriser, which I take it controls gas flow, the further open it is, the more power but lower economy, and as it is closed down, the economy improves, but power drops?
What is the accepted wisdom when running LPG setups as regards fuel? Can you run on on LPG all the time, or is it advisable to run on petrol every so often? I do intend to use petrol when playing and trialling, and the LPG on the road and for laning.
Starting on LPG from cold? Yes or no?
MOT: Does it still have to be done on petrol of can it be done on LPG, given that the emissions are cleaner?
Lots of questions I know!
