Ryobi trimmer

I'm going at this for the first time so here it goes. I have an Ryobi 790r click link. The entire unit tried swimming during hurricane Rita unsuccesful. Every thing appears good, except the upper drive shaft. It has plastic tube between both the receiver socket and the stop on the engine side. My question is, if I remove that stop in order to clean and lub the shaft do I need to replace the stop. If so will a sleeve used with in wire cable connecting work and is there a chance of the shaft being out of balance.

One more question this unit uses 32:1 mix, but I read somewhere that California has to use 40:1 mix. What is keeping everyone else from using 40:1 mix also?

any info is very appreciated.

Hello bob57!

Welcome to DIY!

I think the shaft should be able to slip out with the stop intact from the engine side.

40:1 will work just fine if you use a quality 2 stroke oil, preferrably synthetic. You know, california has their own set of regs on engines, so manufacturers must comply.

thanks for info on the 40:1 mix.

The O.D. of the stop is larger than the I.D. of the tube. The tube end in question is flaired, that O.D. is just a little shy of stop O.D.
