1): A 461 comes with Carb Limiters, the richest the dealer can set the Hi is 3/4 turn out. This is not rich enough for a Max Flow and DP Muff Cover. You must pull the limiters on the carb if you are going to run it this way, or you will burn the saw up. For your set up, I would start by setting the Lo at 1 full turn out, and the Hi at 1 + 1/8 turn out. Then as the saw warms up, tune idle and Hi by ear. At WOT, the saw should break up or the Hi is not rich enough. If it does not clean up in the cut, it is too rich.

2) Pull the Filter cover and the filter. Make sure your control lever is operating properly. All the way down should close the choke (fully). Fast Idle should leave the choke fully open (there is no such thing as half choke) and open the throttle butterfly a bit. Run should have the throttle butterfly closed. Stop shots out the spark.

3) If your saw pops on choke, then does not start within 4 pulls on Fast Idle, there is something wrong.

At this stage of the game, I would put the stock stuff back on the saw and bring it to the Dealer.

461s are generally VERY RELIABLE, they are used as the "RESCUE SAW" by Fire Departments, etc. Hope you did not damage it with your air filter and muffler mod, (w/o pulling carb limiters).
will have to give it a try. is it a pain to remove caps? and it was a pain to start stock, so maybe i should replace dpm, and filter and send it back to dealer

Easy to remove limiter caps. They just need to be trimmed. The little tabs trimmed so the screws can be turned a bit more.
Remove the plastic limiters, trim the tabs and put back onto carb.
BUT it may void warranty. Do at your own risk.

Just use a drywall screw. I use a 2" long screw. Just thread the drywall screw into the limiter a few turns then pull straight out.
The tabs to trim are on the outside of the cap. I use a razor knife or exacto knife to slice the tab part off then reinstall onto carb.

I reckon the saw is just flooding. I'd try switching to fast idle after 2 pulls whether you here a POP or not. With decomps the pop can be hard to notice & saws flood easy and fast.

The caps are very easy to mod and difficult for anyone to tell you did it, if you cut off the tabs with a razor and reinstall the caps.
Yes, but you have to pay attention as i found out with the 880:( i thought i had the tab lined up went to pull it out, but broke it in half instead:BangHead:

it seems to be starting fine now, with or without decomp in. i should probably put an 046 or 066 coil on her next
