Hi everybody,
I'm new here (long reading, not posting). I find this place absolutely fantastic -so much knowledge and fun that I cant even sleep some nights. opcorn:
I've already bought 2 saws - Husqvarna 372XP and Dolmar PS 5000 - CAD is coming really BAAAD :greenchainsaw:
SORRY for my bad English - Czech Republic (EU)
I would like to ask you whether you could me give some advice about my problem. It's with my DOLMAR 5000 (European version of US Dolmar PS 5100) - just rev-limited to 13.500
I bought it with scored piston and cylinder. Saw was quite new - I was said 30 hours running. Bought new piston, under-cylinder gasket, metal ring (thanks) to intake boot. I cleaned cylinder pretty well - not so nice but I tried it.
I fired it up and it idles just fine, but I had to richen H screw pretty enough. Now I have it set to 2 and 1/4 turns out (limitters cut away) and it still turns 13.300 (remember: 13.500 max limited coil). It just go down in revs when H screw set somewhere to 2 1/2 or 2 3/4. It cuts pretty well with this setting (2 1/4) but it seems fuel consumption is quite high (it could be just my feeling). On this setting Irun this saw for about 12 hours (I know, I know..........) and it has compression about 190 PSI.
Today I tried some test with starting fluid to find some intake boot air leak. I fired her up and sprayed some starting fluid around the intake boot. It changed revs and if I sprayed pretty much (fluid - from spray-can through some silicon tube) it died. I took the carb out and cleaned the contact surfaces between carb and intake boot. I couldn't find any disruption there, so I tried to give some plastic grease (vaseline) on the contact surface of the carb and assembled it together. It got little better but I dont know.................
Some advice guys??
Thanks aaaares
