hi my car seeems to miss above 7k under load. i had some water in the tank but drained it off along with the carbs. the engines a c1. can water stil be sat in the carbs or could it be something else? it also melted the fuse in the starter relay last night which the charging wire also goes to??

Has it always struggled or is this a new problem?

Did you change the fuel filter when you drained the water off?

If it's always struggled:-

Have you re-jetted the carbs? For info mine runs 200 main jets, rather than the standard 155's.

What ignition leads are you using? Mine ran badly using silicone / carbon leads, and loads better using a set of the original copper core leads.

Where is the fuel pump, the bike pumps seem to prefer to push fuel, rather than suck. I relocated my pump from under the bonnet back to the boot near the tank.

sounds like its overcharging, could be the regulator thats shot, or just a bad connection. I had the same problem so took the charge wire direct to the battery, no issues since.
