The MK1s had a lean fuel curve straight out of the factory as late as 2016-2017 when mine was produced. Once I had my AT updated in 2019, all start/restart problems went away. The idle fuel curve was fattened up, no need for a high idle to restart.

Cold starts: do not use the decomp on the MK1s, it somehow interferes with what the earlier version of AT was trying to do at cold start/restart.

It has bog unless you let it idle for awhile. I guess it’s okay if you are patient but if you are cutting roads open you want to get in and out

Nothing like putting these saws back in action after they've been thrashed.

I got some good saws from their junk pile

Steve's signature:
Easy peasy start
Easy peasy restart

Puts a Big'O stupid smile each time, one feisty diva.

Six years of trouble free operation, start and go, does not miss a beat.

Not that Steve could not do the same for a 261, don't have one, can't compare.

I put this smashed 261C together after parts became more affordable; BGD and an extra muffler outlet. I'm pleased with it's power and rpm .

Parts are still brutal. That 661 intake boot was over $80. I buy every 261, 271, 291 carcass I can scavenge. Just top covers are all $80 for the 261. I ended up buying standard carb covers to get something cheaper

The peoole who part saws on ebay have kind of drawn my ire at this point.

If you're going to sell individual parts, how about you at least clean them?

This is a pretty Karen thing to say. eBay is the free market. If it's dirty, you pay less. If you pay the same, why clean it?

Principle.

And "pay less" is not what's happening. There is some outrageous price gouging going on.

You are completely missing the economic principle of what I said. Read it again.

There is nobody forcing you to buy stuff from these folks, so quit complaining about it.

Must have found some people who have no problem marking up an uncleaned, mag rotted clutch cover for $70.

If the seller wants to sell it, they will sell it. If not, they'll do that. It's their shït, I don't see the problem. But then again I don't wake up looking for things to be aggrieved about...

Shop around, patience is the one thing I have in abundance.
