Force 21 Carb Q
Firstly, I'm not after comments about how crap the engine is or whatever.
Tuning the engine I accidently wound the lowspeed needle in when the carb (slide carb) was closed.
It appeared to jam and wouldn't open, so I wound the needle back out and it freed up, so I proceeded to readjust the lowspeed needle when the carb was wide open, and now the needle winds all the way in before it stops (carb nearly closed)
I am having trouble tuning the engine (doesn't blow smoke at low speed, and when high speed needle is leaned out it runs very hot)
Adjustments to the low needle seem to be not having any effect at all, it is very slow with low revs and opens up nicely once the revs get up.
It is also sometimes quite hard to start.
Any help would be appreciated.
