Very well done on the LPG conversion. What are you doing about certification? I want to DIY LPG mine, but if I tell my insurance company, Directline - they will void my insurance if it's done DIY!
On to your issue, I strongly suspect cam timing is a few degrees out. It's definately the first thing to check, and won't take you long. I'm sure one of our Notts/Derby members could lend you a kit.
Aditionally, if you're unsure of cambelt/waterpump history, then this is a prime time to change it all!
If you do, though, check the timing before you take it apart, to satisfy yourself whether it was out, or not....
James - I made this mistake the first time I converted. I was 1/2 way through the insurance year and they gave me 30 days notice that they were terminating the policy. Since then I have made sure the insurance company I go with are 100% LPG OK and not anal like others. For my recent V6 I made sure they were ok if I did the LPG conversion mid term, although upon verification just before I bought the kit they disputed this, so I asked them to dig out the initial recorded conversation I had with the sales nerd. Needless to say they are ok with the conversion.
