1. CHECK IF YOU HAVE ENOUGH FUEL AND IF YOUR FUEL TAP IS SET
I had this myself several times, suddenly my engine stopped
working and I just couldn’t start my lady. I was thinking about
all the possible issues, but I forgot to set the fuel tap open…
2. IS YOUR SPARK PLUG FIRING?
The fact that your Puch Maxi won’t start might be because the
spark plug is broken, not having the right heat range or because
something is wrong with the ignition. Get your spark plug out of
the cilinder, hold it against the cilinder, try to start your Puch
and see if your spark plug is firing. If you Puch won’t start
correctly but you are getting a spark, check if your spark plug is
adjusted appropriately (spark plug gap of 0,45mm).
3. CLEAN YOUR CARBURATOR
This might sound stupid but it’s also a common cause. Certainly
when your Puch maxi tank is dirty or rusty, the fact your Puch
maxi won’t start can be because your carburator is too filthy and
clogs the jet.
4. CLOGGED FUEL FILTER – FUEL HOSE
This is often caused by a dirty or rusted tank. If your tank is
dirty / rusty, your fuel filter or fuel hose gets clogged. Go and
clean it! You might also consider derusting the tank.
5. DIRTY AIR FILTER
Again we are talking about dirty… Even if you are like me and
really take care of your Puch maxi like a beautiful women, a dirty
filter can be the problem. Clean it or buy a new on.
6. ADJUST YOUR CARBURATOR APPROPRIATELY
Do you have the right nozzle? Your Puch won’t start if your nozzle
is too big. Their is to much fuel to ignite. It may take some time
to find the right nozzle, but this can certainly help you.
7. FLOODED ENGINE
If you have tried to start your Puch, but without success, chances
are big that your are having a flooded engine. This means your
piston is wet and can’t ignite. Get your spark plug out and start
your engine a few times. Put the piston back in, and now it should
8. CHECK FOR AIR LEAKES / VACUUM LEAKES
If you have worked on your Puch (e.g. replaced the cilinder), this
is the first thing you need to do. Check if your Puch Maxi suffers
from air leakes. It’s very easy to check and solve.
9. REMOVE AND CLEAN YOUR EXHAUST
When your Puch has been standing there for a while, fuel can leak
past the float valve en fill the exhaust with fuel. This is also a
reason why your Puch won’t start. Remove your exhaust and clean it
