Hi Guys,

Thanks for the tips.

Sheared key seems to be fine
I've checked and cleaned the jet again (was clean already) but this
carb doesn't have needle. So couldn't check that one. It has a valve
that opens up or closes with throttle movement.
There is fuel in the bowl and float seems to work fine.
Tried squirting fuel in the carb and related to the amount of fuel the
plugs still seemed relatively dry. I got one loud explosion which
seemed to come out of the exhaust.
Another thing is that the upper plug gets wetter than the bottom
plug?!?
Compression is fine. Sheared key seems to be fine

Getting fitter and fitter with every tip. That's positive though
(bloody manual start ;-))

The next thing I would check, assuning it's a 2 stroke, is the reed
valves. The cylinder with the dry plug could have a broken reed valve.
A simple compression test would be a good indication of reed valve and
piston ring status. They should be within 10% of each other.

Remember, trying to start a 2 stroke with a dry plug also means that
cylinder is not getting the oil needed to lube the rings and bearings,
seals etc. this is where damage can be done.

Sorry, just read where you said compression is fine. Is it a single
carb feeding 2 cylinders? .....Reed valves....must be?

Good Luck.
