Quick intro as this is my first post. I have been resurrecting a 1982 Jawa Supreme 2 for the last couple of weeks. I just want to say thanks to everyone on the board. Using the search in the repair forum and following all of the great advice and tips posted in the threads, I've been able to bring it out of it's 15 year coma and into running condition. No way I could have done it with out this site and all the great advice posted here..
Ok, I just re-removed the jikov carb and re-thoroughly cleaned it and re attached it. I also replaced the spark plug, and by god, the thing purred. After a couple of weeks of sputtering, and belching black smoke and fast idling, it litter aly purred when I cranked it over. It was beautiful...Sniff, sniff.
Sorry (wipes away tears), Ok, problem is it's leaking gas from the carb. When I first let the fuel back into the carb it flooded and leaked. I shook the bike around a bit to free up the float and it stopped leaking, I ran the bike, it ran really well, eventually stalled (I hadn't opened up the choke) but then it started to leak gas out of the little hole just 'below' the main air in take hole.
I assume the float is hanging up although I dont see why it would be. Also, I'm pretty sure the valve seats properly when it's closed. It wasnt doing this before I took it off the last time. I'm wondering if the float might be set to high, and that is what is causing the over flow. I'll take the carb apart (again) but I'm wondering if the float might be set to high and filling the carb with a little too much gas causing the over flow. Could that be the case or do you think it's just sticking/hung up somehow. Like I said, it did stop leaking before I started it. It's as clean as it could be. How can I tell if the level is correct? I'd like to make this the last time I take it off and put it back on for a while. At this point I think I could dismantle it and put it back together with my eyes closed.
Thanks, I'll try to keep posts shorter in the future.
