Okay thanks.In regards to your oil filter I would find out some more imfo about your 261 ,is that the filter that came with the motor , some of the engines had a pin that made a difference for the type of oil filter ,I am confused at yours as does not look like it has the pin so just guessing that maybe your motor is a lot newer but either way I would look into it and make shure there is going to be enough oil flowing when you start it up .
