Reduce smoking very poor revs now
Steam rally is in oxsford March

Turn fuel up slightly until a decent compromise is achieved.
Or turn fuel back up to "smoke with poke" setting and get more air into the engine
to help burn the extra fuel.

You're setting off in plenty of time it's only August

first i have the pancake engine ,the pump is from a banana engine is there any difference in timing

If it's a mk5 smiley then I'm positive the Lucas and Bosch pump have a diff firing order. Sure I had to swap two injection pipes round when I did pump conversion.

i had the pipes with the pump , it runs ok just lacking power . may be time to look for a banana engine

Did you change the injectors to suit?

yes all came from the original engine

Did you pin the fly, cam and IP before installing the belt? Did you slightley loosen the 4 IP sprocket bolts to allow the belt to settle under tension? If you did all that try this.
Pin the engine again, slightley loosen the 4 sprocket bolts, noting where they are in their slots. Put a spanner on the IP hub, withdraw the IP pin and advance the IP clockwise by 1 mm measured in the IP sprocket pulley slots. Tighten the 4 bolts whilst holding the IP in the new position. Pull the other pins out and try to start the engine. If it kicks back it's too far advanced, revert to the previous pinned setting. If it runs watch for smoke. It's suck it and see time as far as how much advance to use, 1 mm won't do any harm. If no smoke try turning up the fuel, check for smoke and performance.

NB. A banana won't run much better than a properly set up pancake.
As I said, suck it and see.

set up as first , will try next step thank you

I am only a newbie to this game so excuse me if I am wrong, but I would have thought that if you hold the belt still and rotated the inj' pump shaft clockwise then you would be retarding the injection timing rather than advancing the injection timing. Hope I haven't confused the issue.
