What's on your bench?

Those 87 carbs are great for power! Little more finicky to tune

What makes them so difficult to tune? [emoji2369]

 

[dustinwilt68]

Not sure they just seem to need more frequent tuning then a hda120, but they make more power

I would guess the larger the carb on the same saw will be more touchy to tune because of the larger venturi. Too big and it won’t pull enough air velocity through the venturi if the saw can’t pull enough air ... which means it won’t pull enough fuel. Common sense stuff. Similar concept if you make the oil hole too big on a bar, you won’t have enough pressure to keep it unclogged if the supply isn’t there (oiler output capacity).

290/390 ported, pop up, timing advance, muff mod and 044 carb. Some local firewooder will be in love! Test and tune tomorrow then I'll pass it around to a few guys to play with. She'll be sold by next week. [emoji6]

This is the first 262 I've messed with.

Broken crankshaft, going to build it faster.

Yes 262, cylinder looks good through the plug hole but I was told it's tired. I'll put a rope in it and see what happens. It will more than likely need a full rebuild.

That one is a fairly easy rebuild, much better than the newer ones..

The 198 conversion runs the best I believe.

Jeff go some anomaly of an 87, his tunes perfectly.

Next on the block for me will be the 199 conversion with the accelerator pump. I’m wondering just how snappy a good 262 will be that way.

What head was on that saw?
Before porting.

Thanks.
Got a new project to restore once I get it set up.

You'd get along great with my uncle

Not worked with chainsaws for almost a year, not that many projects left to build.
But I like tools.....

The inspector on work:


572 Service tools:


550 Mark II Service Tools (personally I think the old 550 splitter was a more safe splitter):


Each time I crank a 346 together I always get angry on myself why I did not bought the crank stopper before. Got no 346 to crank together at the moment but at least I bought the stopper:
