hi Bruce

I have just fixed a Briggs 5 horse power 21 inch deck.
cleaned valves, exaust port and muffler.
i have yet to change the bar blade to its proper position (they had it bolted on upsidedown).

it starts great, first pull.
goes through the revs nicely up and down
But...
when you listern to it carefully it seems to be missing a beat. im thinking timing ???

or maybe something else
I wait your reply
regards Frank

briggsboy,

What condition is the bar blade in?

If it is worn then that will cause your timming problem.

hi Bruce
the blade was upside down and now its on the right way, and its in a good condion.
how ever its still got that very faint missing sound.
thanks
Frank

briggsboy,

Is the key in the shaft (bottom) ok and if so have you checked the flywheel key as it is aluminum.

will do that next

thanks
