Glad to be able to help.

Yes, when I measured and shimmed them they were all spot on. I checked and double checked, I have a lot of practice at this now! The tappets were noisy only on the rear of the engine. I took it apart and found the clearances on the end two had increased, but from memory only about 1 thou. Maybe because everything is new it had bedded in after 700 miles. Anyway I put thicker shims in and its perfect, no tappet noise.

I now use stickersinternational, but they are Uk based I see you are in the netherlands. The correct graphic is on the manual front. If yo7 send them a PDF I am sure they can recreate it for you. Unless they have updated them recently the usual suspects are supplying the wrong graphic in the decal, but probably only a handful of us would know.

If anyone is thinking of replacing the original limiter rotor arm I have just received a shallow replacement from PNM engineering. The normal size Lucas won’t fit.Be sure and ask them before your order. Can’t believe the speed at which they are getting parts out these days. I ordered in the afternoon and received it the next day, only having paid for first class post. Well done PNM and thanks! Well just as it was going so well I have detected an unusual noise when the engine warms up. It sounds like a bearing. I used a stethoscope and believed it was from the reconditioned alternator. I dis

Unfortunately the owners shut the company down.

Perfect, thanks.

I have just bought a Kriket one. I found some info on here that says 95 on the Burroughs gauge equals 55 on the Kriket. The problem is the Burroughs 95 = 95 lbs. the Kriket has a pounds scale, so why is the setting on the Kriket not 95 lbs? Maybe older ones were calibrated in units?

The bearings are one of the easier jobs. Heat the hub and freeze the bearing, just dropped in very easily for me.

Oh yes I’ll tell him.

A decent engineering firm will easily drill it out for you.

Thanks Dave. Steve, Interesting point. The only changes made were float height and choke. When I tune these cars I always found on my S1 there is a position on the idle mixture screw that gives a big boost in power output. Its not very wide probably in the 1/4 turn range. On my turbo I have never been able to reproduce this effect to the same extent. I noticed this time when I tuned it I was able to locate the position and the effect was similar to the S1. Was this due to a change in float height? I don’t really know. All I can say is its now running perfectly. I would know for sure If I swi

Still can’t believe what effect changing the choke size has had. My S1 has always drove extremely well and set the bar. I would say now the Turbo drives even better than the S1. Its a relief after so long to have perfected the acceleration. Your always scratching around in a no mans land with these changes.

WOW JUST WOW! What a difference a day can make! I just took it out for a test drive and no stumble at all. The engine in driving amazingly at all rpms. I took it up to 5000 rpm and it really flew! The solution was the choke. The 35 mm has transformed the car. I still plan on the rolling road, just to see what everything is doing an to ensure all is correct. The steering is perfect as is the balance. Its a different car!

Thanks Andy, I have that already. Car is now running and retuned. The start issue was the ignition timing, which is now reset. I have tuned it again and its spot on. Its running a 43 idle jet 7850 -7 jet holder and 35 mm chokes. Just need the weather to change for a test. If the stumble is still there I will try a 45 idle jet. Trying to get this as close as possible before the rolling road. The 7850-9/58 combination seems too rich for this engine. Maybe the progression hole drillings in the body are the reason? Anyhow the combo doesn’t work in this engine.

Thanks Steve I may look into that.
