Been having enormous problems. I cannot get this generator to start. Let me start off by saying I've checked the timing  , made sure the dipswitches are set to propane and the regulator is set up correctly .. I've replaced spark plugs,wires , ignition coil , mag sensor , cam sensor , control board . It seems as though it isn't getting spark and I can't figure out why! If anyone has any insite or things to try and check please let me know.. I'm getting desperate and running out of money to throw into this thing.  It tries and tries to turn over but times out. At one point it did seem to backfire through the carb but it no longer does that..

We have a category for liquid cooled. I have a 1.6 Cherry that had the same symptoms, found the crankshaft timing gear and key half sheared. Crankshaft and camshaft sensors will not allow it to start. For the best possibility to gain help from us it would be great if you could post the model and serial numbers.

OG1260A is all I can find on it. The stickers were all torn off so I have no idea exactly which model exactly. Sorry if I posted this in the wrong forum. I made sure the timing was aligned with the cam and crank.

Are you saying that you had the timing belt cover off of the engine and aligned the sprockets, are you working with some printed material to guide you? New timing belt ? Have you checked compression on each cylinder? These engines are "interference" engines - the valves and pistons will munch each other if the cam is out of time with the crank. What is the history of the machine?

I aligned the cam shaft with the up arrow and the crank with the line above it just like it said in the manual I was able to find... But I haven't checked compression ... Guess that's my next step then?

Question : if the valves were interfering with each other , wouldn't I be able to hear it grind crunching knocking when trying to turn over?

Unfortunately, you would NOT hear a thing if the valves hit the pistons. If you're familiar with engines, if the valves got bent you might notice the sound of an engine without compression cranking. It will also crank faster than it would if it had compression.

Have you made any progress on getting this engine to start?  

Did you verify that the stepper motor was opening the throttle while it is cranking?  Sometimes a linkage will break or the stepper motor is not working.  Move it to closed throttle and press Manual.  You should see the stepper move the throttle linkage and both ends of the link should be connected.  Verify not only that the stepper is moving but also that the throttle plate itself is moving.  

Which way is closed throttle?  A mirror should do the trick, after removing the air filter, and looking down the intake.
State your problem, not your diagnosis.
