Hi all,

I've been tinkering with my little project restoring my Scott Bonnar 540 (intro here, some further info here)and have some questions/need some advice.

I have been trying to find some information on the correct air cleaner assembly for this mower, see post -> here

After i found some parts lists/diagrams last nite I also believe I may have the wrong muffler on this thing (I ordered one based on the broken one that was on it - and it's pretty damn loud!). I think it's supposed to have the 'super hushtone' muffler (sales image here. After taking the new muffler off and having a look, I can see there is a bolt broken in the block (pictured below, gave it a little rub to make it more obvious). I'm keen to get the correct muffler for restoration. I think the correct part number may be 391492 for the muffler and 222238 for the deflector (300B in parts diagram)? Can anyone assist in confirming? Or is it supposed to have the one with the spacer (300C - though I don't htink I can see any mounting hole for the spacer ( top right?? ))?

Any tips on how to remove the broken bolt? Will an easy out be small enough to get this one?

Also, took the cowling off and gave it a clean underneath on the weekend, cleaned a heap of crud off the govonor blade and in behind the carby and popped a new plug in.. Now it seems to want to run at 100% the whole time, and I cant seem to throttle it back at all, its either full on or off? Have I done something to the govonor/throttle setup to do this?

Thanks,
Ed.
