61/272 conversion question?

[thumbilly]

I've looked and I'm sure it's been discussed on here but if I stay with the 163 carb how will it affect performance. Also how much should I open the muffler?

I take the hole flap out and if you are doing a 272 top end to feed the beast you need the bigger carb if you can. Hope this helps

Anybody have any experience with the Chinese walbro reproduction? How bout the baffle in the center?

 

[rattler362]

I think if you could find a Tilly 260 I think is the right one

I had a Brazilian replacement carb on my 272, never really ran quite right. Tillotson hs-260a made things right.

Tillotson 254 has the same size Venturi as the 260. I can't tell them apart.

Is it possible to split these saws without the special tools?

I have split several without special tools, despite warnings and misgivings. Although it has always been successful for me, the tap tap tap process seems like it requires excessive force and I always worried that something expensive would break. There are many descriptions here of relatively simple shop made tools. I graduated to a small arbor press with wooden jigs and then bought an officical tool. It too will force an occasional POP that sounds catastrophic, but those magnesium cases must be tough. Maybe you can borrow one. Simonian rents them.

When I put it back together should I leave the gasket dry or use some type of sealant. The reason I'm splitting is the gasket spit out on top of the oil tank.

I've had an odd issue with one, the spark plug wire is short by a little so is lays on the cylinder and bleeds spark.... and I've had terrible luck with the Brazilian Husqvarna Ignition parts BTW.

Has anyone else had trouble with these saws pushing oil out like the tank is pressurized

I don't know the best practice, but I use cement on one side.
