Finally pulled the head and cylinder. There was only about 70 lb compression. I guess it makes sense now. Firstly, there have been NO modifications to accommodate a reed valve. But the biggest problem is a broken ring and a beat up piston. From what I have read, low compression will cause hard start...

Excellent. I will do all those things. In the meantime, I got it to run after just a few kicks. It will idle if i keep the throttle open just a bit. From what I could tell, the intake port has not been modified and the piston does not have holes, but I will look closer after I check out the Super Co...

Bullfrog, I will look at the piston as I have the intake and reed assembly off at the moment. I'm new at this, but the intake on the cylinder looked stock. Isn't it supposed to be enlarged for a reed installation? The reed guts are were actually rusty and I left them out. I've been running it withou...

Finally got back to the bike armed with all the info and parts I could find. I pulled the flywheel to change the points and found the crank seal was no longer in place and everything was gassy and oily around the points. Put in a new seal and points. Removed the reed valve guts. Brought the pilot an...

I'm getting very suspicious of the reed/cylinder relationship. I increased the pilot jet size and got a small improvement in starting/running. But very inconsistent. After I get it started it will die without my help. Pretty soon I can't start it at all. I don't think I mentioned it, but the carb is...

Thanks for info on pilot jet and pilot circuit. I cleaned out the carb body and shot air through every passage. Jets are clean as can be, took it all apart and inspected. It absolutely won't start or run if I come anywhere near the choke. Guess I'll just wait for the new pilot jet.

Pilot jet all nice and clean. I will check compression. I was reading about the reed valve setup. It was suggested that the reed inhibits the suction into the cylinder during start up, so the pilot jet needs to be enlarged. I also think that, since the heat block increases the distance from cylinder...

Well that's the thing. Can't get it to idle no matter how many turns of the air screw. Takes me maybe 40 kicks to get it to start, Runs fine as long as I keep the throttle high enough. Plug looked good after I ran it for 5 minutes. Won't start easily and won't idle. Frustrating

I bought a 73 Wombat 94A on ebay about a month ago. Somewhere in its history a carb from a model 95 Combat Wombat was put on, along with a reed valve. I cannot get it to start easily or idle. I figure increasing the pilot jet will help. Also, since it has a reed valve, does it still need the heat bl...

Thanks all. It was actually more commonly called the needle jet. It was missing the little washer that held it snug in place. Plus it was tapped in too tight, the new one slides in easily.

I found the main nozzle a little loose in the carb body. Is this just pressed or tapped in, or is there a special tool to tighten it.
Thanks.
