will not stay running 49 B

[polaschd]

I have just finished putting the engine back together after a rebore .90 I can get the engine to run has good compression but when I take the choke off the engine sputters and dies. I rebuilt the carb and reset the idle and the load needle as directed in the sevice manual still no luck. When I reinstalled the head I set the gap on the valves to ,22 as discussed in a previous forum could this still need additional adjusment. Also is there a trick to putting the shifter lever back in I get everything back in order but cannot get the shift lever to move back and borth between the gear stacks. when the clutch is engaged the flywheel will not turn unless I push extremely hard on the clutch lever.
any help would be greatly appreciated
Thanks
Dean

Sounds like a plugged passageway in the idle circuit. Go to Robert's Carb website and they will tell you what to do. Before I cleaned the passageways, the engine would die if you closed off the load adjustment, meaning no gas from the idle.

Sounds like a service manual would do wonders for you with all these problems

Read the reuest for help I believe I mentioned that I was using the service manual if you have no good comments or help stay out of it

Also check on the outlet side of the carb for leaks, and manifold for cracks/seal on the head. Sucking air here will also not allow you to get enough fuel.

the issue is NOT the valve adjustment. its the carb or ignition. weak spark due to bad pints OR condenser etc will cause this symptom, along with too-tight pistons.

It sounds like you you might not be getting a good flow from the tank. Can you open the drain on the carb and get a good steady flow of gas for 30 seconds or more?

If it's not that, you might have a clogged idle circuit in the carb.

This "when the clutch is engaged the flywheel will not turn unless I push extremely hard on the clutch lever."

I'm not sure about that. Sounds like the clutch isn't set right, and the pulley brake might be too tight as well. Actually, you'd better check your endplay of the crankshaft too. Endplay adjustments change the clutch too.
