717 ENGINE TEMP

[LILJOE]

I HAVE A SIEZED #WRIST PIN IN THE PISTON. I BELIEVE THIS IS DUE TO LACK OF LUBE AND OVERHEAT. WHAT ARE NORMAL OPERATING TEMPS FOR THE CYL HEAD AND CYLINDER. AND WHAT IS A GOOD MIX RATIO FOR THE OIL AND FUEL FOR THIS ENGINE

[1fastski.com]

are you running premix or injection ?

[Technical Support]

If you are pre-mix the ratio is 40:1. There is no standard temp to give you - it should too hot to keep your hand on it, the pipe should sizzle water in a couple seconds.

the pipe should sizzle ? nothen on the motor should be to hot to touch .

THANKS FOR THE INFO I AM NOT PREMIXXING BUT I INTEND TO FROM NOW ON IT WILL MAKE ME REST EASIER THAT I KNOW IT IS GETTING OIL.

SHOULD THE WRIST PIN FREE FLOAT IN THE PISTON

[Technical Support]

I didn't say too hot to touch, but it's supposed to be around 150 deg., and I don't know about you but I can't keep my hand on a hot engine for more than a couple seconds, nor should you be able too.

No the pin should not free float, it should be a snug fit.

#2 PISTON PIN SEEMS TO FLOAT. SHOULD THE WRIST PIN SPIN IN THE PISTON AND ROCK ON THE ROD BEARING ? LIKE I SAID #2 SEEMS TO FLOAT . IS THIS A CONCERN ?

[Technical Support]

Yes, something is incorrect or worn.
