Hello all ,

I just bought this product: RED LINE SI-1™ INJECTOR & VALVE DETERGEN

Because i got recomended using it in my lawn mower , its a simpicity srd 210 , that is equiped with a briggs and stratton egine, 646 cc , v twin , giving 22 hp. I want to know if its safe to use , and how much should i use, since the gasoline deposit is around 10 liters.

One more question, i have a classic car i maybe gonna use the rest of the bootle. One question, its is safe for older cars? and after i pour in the tank, should i consume all the tank? or i havei can leave it there ? shouldnt be harmfull for the engine, leaving it there for some time?

Hello all,

I have a simplicity srd210 with 5 years, but this year i really want to do a deep maintnaince, so im considering cleaning the carburator or replacing it ?

How hard is to do that , the motor is : ENGINE, 23 Gross HP, Briggs & Stratton Twin, Pro Series. Mod. 40N8777-0030- B5

I´m not sure if i should do that, because the tractor works fine , to be fair i dont remeber if he lost power since the 5 years that i have it .

Any tips?
