Stroking a Dolmar 7900

[mettee]

Do you guys forsee any problems gas welding a pipe?

I wouldnt do it personally, but you could braze it.

If you have experience gas welding thin material, no.
If not, probably at first, maybe a lot.
Some prefer it and are very proficient.

I think Cahoon gas welds his pipes

I have the same machine, wish I could turn the hot start function off.

Makes it a challenge firing off on 22 gauge.

Last I checked, 30 years ago, i was decent at it. Didn't know if it would warp or not

Braze gets kinda messy though when not painted

Are they as smart and good looking as me though?

Could the Dolmar crank be taken apart and put back with just the solo rod, then trued and welded?

That wouldnt change the stroke. Just the dwell time.

Gosh what is the name of that shop that does this work?

Are they able to repair that crank? Or does it need a new rod?

I dont think replacing the dolmar rod with the solo will accomplish the stroke. The stroke is in the swing of the crank. There is a whole case on ebay that has a complete crank inside, I think 150.

Crankworks in Arizona does great work too.

Every saw I have added case compression to has been a really good runner throughout the power curve. I have not tested it by itself though. Gunna have to try that one of these days

Terry is right. Decreasing crank case volume typicaly makes slightly more power at the expense of power curve width.
