Hey there, I've got a '94 FC600 that I can't get to start. I got the bike knowing this, however the previous owner said(and I later confirmed) that the bike has good compression and a good spark and therefore it must be a fueling problem. He said that the bike was running when he parked it at the end of last season, but would not fire up when he tried to start it this season. Its got a VHSB 38 flatslide carb(from what I've read, the less common type) There have been a few things I've fixed since I got the bike 3 days ago:
1st: When I first put fuel in the bike, it immediately started dumping out of the carb and this told me that something was stuck in the float bowl. I proceeded to pretty thoroughly clean the float bowl and jets and since then it no longer pukes fuel when I put it in. Afterward, however, still no start or even smoke after endless kicking.
2nd: After reading many threads, I figured I might as well adjust the valves to rule that out as a cause. However, after doing so, the bike was just as dead as when I got it
3rd: After reading the owners manual, I noticed my decomp level was grossly out of spec, so I tightened that to around 2mm of play. Then, after many kicks(choke on) the bike start back firing and popping a bunch and suddenly came to life...for about 5 seconds. After that I could not get it to start or even pop again that night.
Today, after tightening the decomp cable a little more and screwing in the screw on the carb to 2 turns out(I believe it's an air screw, not a fuel screw because I have the VHSB carb), choke on, I was again able to get the bike to start for a few seconds. Immediately after it died, it started again on the first kick, ran for about 10 seconds, then died. After that I was barely able to get it to even back fire and pop for a while. After letting it cool for a while, I came back, gave it a bunch of kicks, but have only been able to get it to occasionally backfire or pop but not start.
So, any ideas?
I've heard that there are consumables in the VHSB 38 carb that should replaced, anyone know what these are and where I can find them? I believe the jetting specs should be alright because the previous owner had it running fine last season and he was around the same approx. altitude.
Also, after reading a bunch in this forum, I keep hearing people talk about an "Owners Doc" and a "Resources Section" of the website, but I have not been able to find either of these. Could anyone point me in the right direction?
Thanks,
