It probably dresses better
If it was coils the it would effect 2 and 3.Swap the plug in cylinder 3 with the plug in cylinder 4? It might be a plug breaking down.If plugs are ok, then it is carburettor, incorrect valve clearances or piston ring issuses associated with cylinder 3. Would not be the first time someone mixed the shims up when doing the clearances.A compression check will rule out carburettor being a problem.Teedeelii; Check the valve clearances and then synch the carbs. Might be no harm to do a compression check also.

So plugs must be OK?2nd cylinder works, so coils must be OK?Coud it be the cam chain not fittet properly (timing)?Or the carbs?Valve clearances were OK, nothing was touched.
