Welcome to TMBF mate....... 8-)


I would say you need to go over all the basics again mate........Valve Clearances, Spark Plug, Coil, Carb set-up, etc..... :wink: Did you replace the air filter? Does it have the correct quantity of oil in?

Sorry if this advice is teaching you to suck eggs.....but a lot of this stuff does get missed and can cause poor running problems.

If I were going to hang my hat on one thing, I'd be checking the compression and valve clearances..... :wink:

The rubber boot split could be the issue,

Air filters and boxes are normally designed for that carbs tuning in specific, giving the correct air/fuel ratio.

Like normally, changing to a pod filter can leave your engine running slightly lean,


Your carb could be intaking too much air than whats designed in manufacturers airbox..


But as Tango said.. Normally the simplest things get missed, and normally there is a simple reason behind things..


:D

How true. When my much loved Capri died on me a few years back a quick check under the bonnet it was one of those simple little things that had caused it to stop.


A piston had come through the side of the block.
