I have a Countax ride on Tractor here in England. It is fitted with a Briggs engine reference 286707 which has a gravity fed LMT Walbro Carburettor. The engine starts easily but at normal temperature and maximum revs it runs for about 2 minutes then 'splutters' for a second or two then runs normally again then the cycle is repeated. I have fitted a new spark plug RJ19LM and use new fuel. The air cleaner is good and I have washed and oiled the prefilter as per the instruction book.
Any ideas what might be causing this problem please?
Thanks in advance for any help you can give.
