I've got a DHZ DPRO 160 with the z160HO engine, except the thing is working properly all the time.
Some time when i start it the engine fires perfectly, revs smoothly etc. Other times it will splutter upon start up and if i'm lucky i can squeeze the throttle and it will all just into line and start revving properly and create the normal amount of power. However the problem is some time it starts and just fires like crap, it will splutter and will hardly rev.
- It maybe important to mention the engine is fairly new.
- I've done the valve clearances (and i'm fairly sure I have done it properly).
- I was told the breather hose on the top of the case may have been kinked, but it isn't.
- If I kill engine properly and get a clean kick it starts fine usually, but if it kind of turns over a little before i get a good kick it tends to start like ****. Which makes me think it is a timing issue or something.
I've been told to change the spark plug so i'll do that tomorrow, but i doubt it is the problem because when its running it seems to spark properly and create plently over power.
Another thing is it doesn't seem to idle perfectly, which indicates to me it may be a valve timing issue but i'll check that a number of times i'm sure it has to be right.
Any advice you can offer will be greatly appreciated, cheers
