Need help with my Baja 5b.

[Allan hamilton]

Hi guys IV run my Baja 5b today.
wen I was done & heading home.
found that my Baja had Oil inside the muffler pipe?
Could it be a Gasket or something like that.
Can any one let me know Pls.

It’s a two stroke engine, oil is burned with the fuel and exits via exhaust. Having said that I can only assume you are running pig fat on your air fuel mix and needs to leaned out..

So lean out on the high or low needle mix.
And what do you mean by pig fat.?

If you don't know how to tune I say leave it there if your happy with its performance. Please read up on tuning before messing with the needles. It could cost you an engine.

Pig fat means very rich. As Crucial said if you don’t grasp what you are doing leave it as is! Worst case is you’ll foul some plugs. If you decide to educate yourself make very small incremental adjustments, a small adjustment will have a large effect. If unsure err on the side of running rich.

Here is a video that explains carb adjustment and how to tune. Start with baseline settings of you engine provided by manufacturer.

Watch the beginning then skip the stuff in the middle about break in but learn to listen for the sounds of the engine indicated around 15:30 into video.

If you learn to tune 5th scale life becomes easier and doing it is pretty satisfying, but do so at your own risk and understand the consequences if you lean out too much.
