Status: offline 		I am currently working with the prototype/Beta BCMA-MA2 ignition unit which runs 4.8v to 14V in order to allow the use of 2 and 3 cell lipo batteries without the need of power regulation. My BCMA-MA1 unit prefers to run on 4.8 V but the BCMA-MA2 unit prefers 6 V and up and the higher the voltage the hotter the spark. This unit will be equally as reliable. I have sold a couple of these units on some Zenoah G26 EI conversions and have good results. I am going back to the rubber spark plug cap with ground lead. I just feel more secure about this. The ignition units have built in resistance so they do not necessarily need a resistor plug and right now I having them developed to use the NGK CM6 mini spark plug. The reason for this is because this ignition is going to be used for another engine company that I cannot name at this time. The BCMA-MA2 ignition will be a full production unit that will be available for OEM.

Status: offline 		Those early Walbro carbs were a hit and miss. 1 in 4 of those carbs were bad so I ditched them for the zama carbs. These carbs are much better where I may have 1 in 50 that are bad. Note! This is not to say that Walbro carbs are bad. They are not bad carbs at all. This situation had to do with the supply and specific model of carb that was used. If the engine runs fine, than don;t change it. When they work, they work well and they will match your ignition module. If you upgrade to my czama carb, your ignition module would have to be changed as well.

I would try it first, if you have problems with it, let me know and I can help you with a retrofit on it.

Status: offline 		Adam, I have been following these posts. I sent my engine back, which you received friday. See what you think about my engine, but maybe a switch to the Zama/CH ignition combo is in order as you mention above. I have gone through three of your walbro carbs and still had leaking and/or problems running the engine. Thanks.

On mine is written 0714 WT548. Does this means anything?

Status: offline 		Blackbaron,

Thank you for the reply about your MA2 ignition system. Will you go to the rubber-cap/ground-strap on MA1s also? The plane I am assembling is a Kange Waco and it will use NiCd or NiMH batteries. The MA2 would probably not offer any improvement over the MA1 in that installation, correct?

I have your engine. I will be putting a Zama C1-Q (With Choke) 12.7mm on it along with a new intake manifold. I have your new C&H ignition on order and will completely retrofit it for you. This will make a world of difference to this engine since this was an early model revision 0 engine.

Status: offline 		This means that with the Zama C1-Q 12,7, being smaller than th 13,5 no need to change the EI?
I was having a look on my engine:
The EI is exactly as the one pictured in your web-site, apart the BCMA Engines writing.
The cylinder is not polished, but black painted, and the spark plug is a Champion RDJ8J. Apart this things looks the same...
You know, this is my first gasser, I'm not that experienced with them, so I worry everything...
I'm just wondering from where it comes my engine. I bought it from an advertise...

You will love your engine when you get it back. Adam did the same thing to mine and it it is awsome.
Some people have a green thumb. Adam has a gas thumb (not methane).

Status: offline 		Not all SPE engines are mine. There are many of these sold by non-authorized sellers in flea markets or other parts of the world so they may not necessarily be my engines. Coming from a non-authorized dealer these engines are straight from the factory with no pre-testing done and 95% of them are old stock with all the old problems as discussed in previous threads. You will not be doing yourself any favor saving a few bucks buying one of these engines. A BCMA-SPE engine is your safe bet because I guarantee them to run and I repair them and offer aftermarket parts and keep replacement parts on hand for full 2-year warranty service. Tech support is free for as long as you own this engine.

Note! If you have purchased one of these engines and have a problem, feel free to contact me and I will repair it or retrofit it for you but you will have to pay for return shipping and parts. Labor and tech support however will be free.

The BCMA-MA1 ignition will not feature the rubber cap. This ignition will be replaced with the MA2 ignition in a few months.

Status: offline 		Brillelli engines is the exception to the rule. They are authorized dealers and thier engines will be covered the same as the BCMA-SPE engines. If you cannot get resolution or needed parts from Scott or Mark at Brillelli you can contact me and I will take care of you as if you were my own customer. Scott and Mark at Brillelli engines will give you 110% customer support plus you get my backing as well. This will work both ways as well as my other dealers. I will post my authorized BCMA-SPE dealer list on my website so you can be sure that you will be covered under warranty and tech support.

SpacewalkerSG is also an authorized dealer in Singapore. I am not affiliated with him but I do know he does his own QA for his customers.

Status: offline 		Adam,

what to say more...I'm astonished for your support...I'd sure buy the engine from you if at that time I would know you exist!

Thanks again.

So what ultimately am I going to be responsible for as far as payment? I would hope that I won't be charged for a complete CH ignition and Zuma carb since I was having problems with this early version engine?
