LOST SPEED .

Pete and Nic do that too.

 

I'd say more an engine problem if it fuel/spark it would run lumpy and shit not just slow

 

yes def got a problem....... max full chat just about 125 - 128 well it will have to wait until i can afford to get it looked at properly

 

On a private road of course

 

Hopefully you won't cause any further damage or blow it up

 

Ok so your prob as much as 50% down on power, that's a hell of alot.
Not sure of the Blackbird but it might be worth checking the fuel pump first. Gravity feed on it's own is not sufficient to feed the carbs enough.

 

I have a feeling that as I ran it out of fuel a couple of months back, there has probably got some shite out of the tank into the system. so while they are investigating this vibration issue I will get them to look at the fuel system and put new plugs in for me.
