Hi all
Wonder if you could please advise.
On 3 of 4 recent occasions when I have taken my BT7 for a weekly run of about 12-20 miles it started to misfire after about 8-10 miles. Today was the worst. Having run really well it started to misfire badly for about 1-2 miles and then recovered and ran well again.
Turning on the ignition starts the fuel pump ticking as it primes the fuel lines. Starting is no problem and it warms up nicely and then runs really well, smooth and responsive.
My strategy is
- Clean and inspect the plugs ( new NGK BP6ES plugs fitted about 1500 miles ago)
-Inspect the distributor cap ( new "quality cap" leads and plug caps fitted about 200 miles ago)
- Fit new rotor, contact breaker and condenser. (New sports coil fitted about 600 miles ago)
- disconnect the white and black wire from the cut off switch in the boot/trunk
I would be surprised if it is a fuel problems a new aluminium tank and electronic SU fuel pump were fitted about 15000 miles ago. Also an in line fuel filter was fitted before the carbs. I also didn't think that todays misfiring would be down to just one of the 3 carbs float bowl needle valve sticking. I could however easily fit a new fuel filter.
Have I overlooked anything??
Thanks
Steve
