Welcome to the Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines - Enjoy!
Bonjour Hans,Personally, I have never dared to put any thread locker on my little engines, considering the small sizes of the different screws, nuts and bolts and their possible fragility when unscrewing.I wish you will find this alkylate type of gasoline, it is really great, before I used to put 4 drops of 2 stoke oil in the tanks with SP98. I can see it on Amazon :https://www.amazon.fr/s?k=essence+alkylate+2+temps&crid=31S8BUW01EW35&sprefix=essence+alkylate%2Caps%2C105&ref=nb_sb_ss_ts-doa-p_2_16
