I'm stuck. Just bought a new Spectra G w G 26/hatori and can't seem to start the engine. The engine just burp for half a second several times and that's all I get. Went through two broken pull starters and now luck yet

Anyone living in Southern Calif. that can help me? I bring it over.

Do you guy use the carbon plate?
Any problem with the RF sleve around the coil? B. Hanson doesn't like it.

Needles set per manual and B. Hanson.

Any help would greatly appreciated.

Does it seem to always have spark?

What I would do (I'm no expert)...

Prime the crap out of it (flood it with the primer bulb) to make shure the carb parts and piston rings are wet enough to seal and work. Then pull the spark plug out, and pull the rope several time to unflood the cylinder. Now everything should be primed and wet, but not flooded. If it wont at least fire now you are missing air or spark. Check throttle trim and spark. If it runs for only a couple seconds, it is a fuel supply/delivery problem, check lines, clunk etc.

If you have broke two ropes, there is a small chance the compression is lacking due to wear. There should have been some assembly lube from the factory, so you should be ok.

Good luck!

I tried exactly what you said before...prime it...remove the plug... and pull start...burb for 1/2 second. Yes it alway has spark. Brand new engine, new spark plug.

You didn't mention your needle positions but I suspect you need to richen your low end needle about 1/8 to 1/4 turn.. do that and let us know if it doesn't crank.

Throttle trim too low? Sometimes we get caught on simple things...

You can also remove the air filter and check the butterfly. Then open the carb, stick you thumb on the air opening and choke it by pulling the start.

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

Thanks for the responses. Needles at 1 1/2 for both (B Hanson suggestion). Throttle is set up correctly. I had a G23 before and it run fine. Keep in mind that this is a NEW g26 engine .

I took the carburator I notice is that when the piston goes down it barely show the ring and when it goes up, I see the whole piston shaft. Is this normal? I don't see the top of the piston like in my glow engine. Please check your engines and tell me if yours are the same.

think thats normal for the intake side

if youre still breaking the pullstart bruce H sells the metal rings that go in the pullstart to curb this problem

If youve been trying to start it or it has ran and died a few times check the spark plug it may be fouled...if you have the champion plug swap it out for the ngk (don't have to be irridium but you will probly want one in the future). With a dry engine with a new plug and the primer bulb primed choke if you have a choke or open 1/4 throttle and put the back of your hand or thumb over the stack and pull a couple times (should try to fire/run but dies) then take the choke off or remove your hand and within 4-5 brisk pulls it should fire up if you have your trim opening the throttle enough.

In the intake you can barely see the ring if you look in the exhast side you can see the top of piston

I think a shield is what is causing the problem. I will try without it . I see spark when I pull and this can't be normal. I cut the shield 1/4 inch per manual but probably not enough.

Some help

Do not use the spark plug shield wire. It was never needed in the past and isn't needed in my case now. Having to pull off the cap, put that shield on and put the cap back on without breaking something is difficult enough, and maybe you caused a "leak" of the spark doing that.

On the other note, a burp for 1/2 a second and quit means in general (barring spark issues) is that the throttle is too closed. Open it some more and try again.

I will be removing my carbon plate this weekend and making whatever adjustments necessary to the throttle arm to make it work without this spacer. I will add some pictures to my gallery here of how everything looks when I get done.

Thanks for all your helps. In the end it wasn't the fuel, plug, or needle...IT WAS the RF shield causing the short and why the engine didn't start.

It run great now. Thanks.

Glad you got it sorted! Enjoy!

RF shielding

The RF shield IS THE PROBLEM! I went though the same crap. Took it off, and the engine runs great. Now I have radio interferance instead! The shielding needs to be trimmed back at least 1/4 inch from the spark plug boot. If it is too close to the spark plug it grounds out the coil.

Interesting

I've flown my ship 7 flights now and no interferance problems knock on wood. I don't have the sheild, never had it before in my 1005 gasser and wasn't about to start with this one. Instead I mailed my shield to Nick in England so he could use it to solve his RF problems

Take a look at my setup here:

Maybe I did something different than you (the way I setup my wires and such) and that is why I don't have any RF issues?

If you are using braided shielding with the standard, unsupressed Zenoah rubber plug cap, you will experience grounding of the HT as this plug cap has innadequate insulation as standard which allows the spark to track through the rubber cap onto the braiding.

Change the cap for a proper NGK type, re-install the braiding ensuring its earthed to the engine or remove the braiding and go without it.

If you run NGK plugs be aware that they have a lower resistance, typically around 11-12 ohms compared to the Champions that can be as high as 20-22 ohms (these are the non-iridium types) although in my experience the NGK plugs keep their reistance value wheras the Champions can lose a lot of resistance value (50%+) over a short period of use.

Hope this helps.

Paul.
