Re: Rev Counter Bounce, Backfire & Stall

Erratic/unusual behaviour of the Tach does suggest the LT circuit as Vic previously stated. The exhaust backfire is commonly unburned fuel - unburned due to ignition fault causing weak or no spark in many cases. As the car will not start, it may be easier to locate than an intermittent fault so time...

Re: 12H2709 ‘big head’

If you substitute '6' carbs for '4' (hs or hif) on a stock head you will lose low end torque and power. you will gain a bit over 5krpm. the rest of the engine has to be able to breath to make use of them. regarding the increase in power by putting a 12H2709 head on, i'm afraid it's so minimal that y...

Re: Toggle Switches Query

i cannot answer your question, but i would say beware reproductions and check spec. some cheap switches are only rated at 2 amps and without a relay your heater switch will draw ~5.

Re: Hidden Music Source

Slightly off-topic, but i think will be of interest to both Ruabon & Peter. Not far from you is a hill by the name of Bwlch-y-Groes. Just outside of Bala. Quite stunning scenery, but I also heard (in fact it was on a TV program recently) that it was used as a hillclimb proving track in the devel...

Re: valve seat inserts

I have to say that I have not come across the insert scrape test before. but even Peter Burgess told me that it's not easy to be able to tell if a head has been converted...even for him. i am not sure it's so straightforward, especially from a photo. i do hope you lapped the seats. they should be a ...

Re: SU Carb needle profiles

Mike well the best way to find out what is happening is with an AFR sensor. I run one with my supercharger as it's crucial not to go too lean. It sounds like your needle is ok at idle, ok up top (good power), but far too rich at cruise type speeds. that's how i found most off the shelf needles and i...
