G340 full mod won't start

HEY ? What's wrong with base 1107 settings ?????

not dougstar settings

If your plug is wet it's a spark issue or its flooded like crazy. The connector on the coil is just a ground to shut it off. It wouldnt shut down if it was connected.
You also need to remove the flywheel to see if you broke the key.

Ok, it's about to rain today. Between tonight and tomorrow I can check the flywheel and adding fuel directly to cylinder.

You said the plugs wet, right? If so fuel down the hole isnt going to help it any.

I’ve heard of ppl having issues with those quick disconnect pieces. Try to run it without them ??‍

I took them off of my Baja.

If you have some starter fluid, I would pull off the air filter and give it a spritz and see if it fires up . You have spark right ?

?Where did you get the 990 from?

I guess you are correct. I have never had a 1107 out that far. ??

?Where did you get the 990 from?

The 990 was from OBR, ordered with the engine

 

[DougStar]

Here are the base carb settings ?

 

[crucialRC]

When in doubt stock it out?

First problem is Those quick connects, I have many engines and attempted to use those on an obr Reed 32....to no avail they were chocking the fuel delivery....remove them....

next take carb completely off drop in a few droplets of fuel with plug in. Raise vehicle “Wheels up”....it’ll start and rev high as hell for about 4 seconds then die...This is how to unflood engine.

next put carb and gaskets back in place with out quick connects ...good luck....

I tried carb off and fuel directly into the cylinder. Admittedly the wheels were on the ground. It didn't even try to fire. I also did a compression test and got about 110 psi. I ran out of ideas. The engine is on its way to OBR so they can take a look.

?I didnt read that you replaced the spark plug after you found the wires were not connected to the coil and you seen the plug was wet. Did you put a fresh plug in after that was found? I still think it is carb setting being too rich on the lsn

Yes, I did get another new plug. Well stock carb setting for the low on 990 is 1 1\8. I normally run between 1 and 1 1\16. But when I have trouble starting, one of the first things I do is reset it to stock.

Hi, did you ever resolve this issue. I’m having the exact same problem.

Based on his 110 psi compression, I'm guessing the piston / cylinder were scored. Unless he didn't use a proper small engine compression gaugeto take the reading.
