Project Stumpbroke Dolmar 5105

[Brian VT]

Thanks for the compression response.
I think my 5100 is @ 190#, stock, so that's why I was curious and I was surprised that the squish was .030 on that 5105.
I'll have to check my squish one of these days.
Mine is fine with 93 pump gas and no noticeable gain from 100LL (I do tune the carb. for it). I switch to 100LL in the fall only because my local station stops selling ethanol-free gas and I don't want to worry how long my OPE gas might sit around.

So either Stumpy is a genius or the 346 cheerleader squad hasn't woken up to cry Foul yet...? A Dollie dethroning the pinnacle of all saws?? Wow tough to sit by and watch ...

Nice work Stumpy !!

Not sure about a genius, but Stumpy can sure make a saw cut strong and fast!

Now for the 346 comment, it takes some work to get a dollie to beat a 346xp! :msp_tongue:

Funny thing is it takes work on a 346 to beat a stock dollie

Both good saws, you'll get no argument fro me. Just that the 346 is better for my needs.

Geeze Stump , that intake port looks HUGE !!!

 

[blsnelling]

On the 5105 I get 33.5 - 30.5, for a 3 second improvement.

On the 7900 I get 26 - 24, for a 2 second improvement.

I know, I barely cleaned them up.

 

[Jacob J.]

I need to have you barely clean up the transfers on my 346.

 

[Stumpys Customs]

I need to have you barely clean up the transfers on my 346.

Would be glad too

If I'm not mistaken, that 5105 of Heavyfuel's edged out the ported 346 of Andy's in cant racing... I do remember it being real close...

Was that running 3/8"'s also?

That is cool that this saw was pulling a 20" 3/8" well.

Great job as always Stumpy!!!!!!!

[blsnelling]

I'd rather run a 261 built like this than a stock 70cc saw.

 

[jropo]

Thats quite the weight loss program you put that Dolly on Stumpy.:msp_thumbup:
Great work as always!
Good to see you posting again, I was going through build thread withdraw.
