Engine losing power under load

[graham_fuller]

My new engine has developed a major loss of power which I think is electrical.Just wondered what everyone else thought. I was driving it last night (yes in the pouring rain) when it developed a major loss of power at low speed. This continued until I finally stalled the car once I restarted it it was fine.
So I am a little confused.
Any ideas?
Cheers,
Graham

hi graham, have you had a look at your coil?
i had a similar problem with an old EH after spending money getting carb rebuilt, tuning, etc, turned out to be a faulty coil.

Hi Dean,
Is there a method of checking the coil and can it be an intermitant thing?
Cheers,

Graham,

If it happened in the wet it is more than likely a tracking problem whereby the secondary ignition circuit (coil/cap/leads/plugs) was arcing through carbon or moisture to ground. This is commonly either a crack in the dizzy cap, or in the coil tower. It could be lots of things, but look here first.

Good Luck,

Craig.

Hi Graham
you can check the tracking in the dark makes it easyer, I had a seized advance and retard weights in the dizzy on my p/van hope this helps
