Having cleaned my McCulloch air filter and changed the spark plug, my 436 still dies after starting procedures have been followed - are there any repair facilities in South Devon who can help?
Briggs and Stratton in Exeter have always serviced my McCulloch chainsaw and mowers, excellent service, don't have a number for them but i'm sure you can look it up ;)
