I have had a twin carb ea 81 motor with the d- shaped twin siamese exhaust ports fully rebuilt. Has had a "flat spot" on hard right hand turns from the start. Otherwise has been running very well. Now done 5000 km. Borrowed a compressor and have blown out all fuel lines; replaced fuel filter; fuel pump appears to be have no problems. Installed an electronic dizzy with the rebuild but had to set it way off the timing marks to get it to run. New dizzy cap and rotor. Decided to go back to the old points dizzy today. No improvement, except that the timing marks line up again.

Sprayed some carby cleaner around and it almost stalled when I blew it near the throttle shafts. Any thoughts...can these be replaced or rebushed? The shaft between the two carbys that the accelerator cable connects to, which then accuates the throttle shafts also has a fair bit of play in it.

What do you reckon.....

I remember a board member Edrach had a problem similar at one point and I believe it was a loose nut on the coil. You *may* want to try that, but after that I don't know.
