Hello Mr. Cox:

Thanks for the reply.

Perhaps a straight 10-30 synthetic engine would be a better subtitute than ATF, I will try it to see if it makes the engines start better.

I became suspicious of ATF when after I flushed both glow and Diesels with carb cleaner and primed them with fuel, they both started much easier! Perhaps I will use the ATF only for long term storage.

Stay well,

Franchi
