Default OS .81 FS a valve clearance

What are the intake and exhaust valve clearance dimensions?

Thank you,

Robert

They should be in the Manual.

ORIGINAL: DSTIEBS

They should be in the Manual.
Yes, you would suppose that, wouldn't you? But they are not. That's why I asked. However, I did find the dimensions through other means. It turns out that they are the same as the .120 FS (and perhaps others too). The valve adjustment tool kit p/n is the same as the one that I possess for my .120, therefore the valve clearances are the same. Thanks for your help.

If you have the valve tool kit, the thin feeler fits and the thick one doesn't when you adjust the valves when they are off the cam. If you have our own gauges, the thin one is 0.04mm and the thick one is 0.10 mm. Again, you have the valves off the cam, and the thin feeler fits and the thick one doesn't.

The tool kit comes with the instructions, too.

OSMG6334 72200060 GAUGES TOOLS 4-STROKE US$11.99

These parts can be ordered through any hobby retailer who sells O.S. Max engines and accessories.

Thank you, Bax. I used the one that came with my .120, and I am now back in business.
