Tried to fire up the 25CVA yesterday. First it had no spark. The points were corroded. Now I had a weak spark. New plug. Good spark. The saw would start if you choked it, pulled once and then opened choke, pulled again. If it caught it would only run if you could get it to WOT. It won't idle down. Turning the jets had very little effect.
So today I took the carb apart again. Soaked it in carb cleaner. Double checked gasket orientations. Readjusted fuel metering needle. Blew out the fuel passages with compressed air. Reassembled. Saw would now start and run. The H jet actually did something. It still won't idle down properly.
Took carb apart again. Turns out one of the three low speed jets was totally clogged to the point i didn't know it was there. It was hidden under the small internal gasket in a WA-19 carb (no welsh plugs in this carb). Blew it out well. Reassemble everything again.
Saw fired up and actually idled. I was able to adjust everything pretty easily. Made few cuts in a 12" oak long. Nice running saw overall. Now a buddy already wants to trade for it.
One question: Is it normal for fuel to weep through the duckbill check valve in the fuel cap?
Overall opinion of saw: IT NEEDS SPIKES!
On it's collar...and purple hair....and a P.E.T.A. sticker?
