Hi,
Ihave a 2nd hand(flown 1 season I'm told) Zenoah G45- with CH ign.Ran fine the first 5 or 6 times I started it, then the last time
it would not even pop.-Carb was very wet- Took plug out and was bone dry. Tried later using full throttle, and thumb choke, pulled
plug and was dripping, cleaned plug , opend low end and it started in 4 or 5 flips. Stopped and adjusted low end 3 times till it
was running perfectly, good transitions and started with 1 flip.
Took off and flew with different throttle settings and after about 5 minutes at roughly 1/2 throttle- motor died-After landing I checked the plug and again the plug was dry.
Disassembled carb and found a very small amt of lint like material in the screens, cleaned and blew out the carb- reassembled
(diaphram on top of gasket on 4 screw side and gasket on top of diaphram on 1 screw side-butterfly in the right direction.
Could feel air puff coming thru the hole in the mounting block when rotating prop.

Replaced carb- and nothing, carb was wet on both sides(removed plates after priming with choke and open throttle) but plug was
dry.
Can anyone explain would is happening and is it more than likely fixable with a carb repair kit.
Thanks

if you had dirt on the small net, you may some dirt on the small niddle+spring under the black diaphram !!!!
1.make sur no holes are on the diaphram, should be only one in the middle normaly!!!
2. remove diaphram and clean the niddle+spring - this is a major fuel pass in the carb.
3. do you get a spark at the plug?
4. ch battery fully charged??!!1
5. plug gap is normal - not to big/small use a fillergouge!!!!
6. oil/fuel mix is correct - zenoha is 2.8% oil. chechk the manual to be sure!!!
7.needle seeting: both should be open 1.5 trund from spring stop this is the limit!!! do not pass this stage!!! than you start to adjust over that as needed. try be rich as possible for the first 3-4 times, than reduce accordence to need!!

safe landings

Thanks for the reply,
Have good spark and when I got it running, it ran fantastic, then when it quit, I checked and had fuel in the carb on both sides
but the plug was dry- I'm sure if I had fuel getting into the motor it would fire, but then how reliable it would be is the problem.
m y only guess so far is the diaphram is to weak to move the needle,( it is clean and moves freely by touch) but strong enough to
pull fuel into the carb. At least I hope that's the problem and a carb kit can solve it.

Thanks again
