You should be able to buy a thread chaser (even in Oman) like the one pictured.

Hi Al, this is great info.
I'll chase the chaser here.
I am sure I can get the NGK plugs somewhere here.... it will take a while.
Is 0.04" (= 1.01mm) a good gap? I head that idle is better with wider gap?
Any opinion on BP6ES or BP7ES beeing too 'cold'? Using BP5ES?
