Could be the hooter valve or poorly gapped spark plugs or old spark plugs which happened in my case. I replaced them with new NGKs plus little bit of dielectric grease on the tips of boots of the DIRECT IGNITION CASSETTE and all is well again.
( Could be a dying D.I.C. or C.P.S. ). Could be a dirty engine air filter ( a dead rat in there ).
starting from cheapest part;
Vacuum lines
Spark plugs
Hooter valve...
Fuel filter...
Check your service records for parts replaced already.
