I got myself a helicoil kit but I'm afraid I've made a bit of a mess of it.
OK it was getting dark and I was tired but that's no excuse.
I drilled out the one hole and that was OK but I messed up on the other one and drilled all the way through the insulator block.
No one to blame it was my fault, does that mean I have to get a new one??

I've used this stuff and it performs as advertised.

Hey Falcon32
Don't sweat it dude.
You could just use the block with the hole all the way through. The bolt should seal it just fine.
If you are worried, Do as fhm101 suggested. If you can't find the exact product he linked to, there is most likely a similar product at you local bearing / automotive store (possibly the same place you got the helicoil from).

If you use a bolt to space out the hole, Make sure it goes a little further into the the block than it would when the engine is assembled.

Great news I had visions of trying to get a new one on a slow boat from China
Even better news I just found that epoxy available at Amazon here in the UK

I did find this one though available here, do you think it would work?

The repair outlasted the rest of the motorcycle. If it'll stand up to that kind of heat and abuse, pretty sure your little airplane engine wouldn't cause it any stress. I actually use the stuff quite a bit in place of solder on metal to metal connections (because I'm woefully terrible with soldering)

I have a SPE 26 that has a WT 433 on it .

the orginal Carb was a WT 419.

The WT 433 works a lot better.

[/quote I guess the carbs that come stock are ok..but are copies of the walbro...My 15cc ran ok for a while then would not draw fuel well , hard to start, poor transistion, then would not take full throttle no matter where the needles were, seemed a little restrictive also. I had a couple of 190 walbros and tried one..works very well with better power and rpm, I guess some are ok and some are not.

the carb on my RCGF 15cc would never run right from new and i found the high end needle had snapped off in the carb, supplier wouldn't take any responsibility saying i must have screwed it in too far... not the case. so i have had to buy another at an extra cost to me and would have preferred to have got a walbro not another bad copy

Easy to do
RCGF 15cc Carb - replace with one attached to a JBA 15cc
RCGF 20cc Carb - replace with carb attached to DLE 20cc
RCGF 26cc Carb - Replace with one attached to a DLE 30
RCGF 45cc Carb - Replace with one attached to a CRRC 50
RCGF 50cc Carb - Replace with one attached to a CRRC 50
RCGF 55cc Carb - replace with one attached to a DLE 55
RCGF 62cc Carb - replace with one attached to a DLE 55
RCGF 100cc Carb - replace with one atached to a DLE110
RCGF 110cc Carb - replace with one attached to a DLE110
RCGF 150cc Carb - replace with one attached to a DA150

Preferably whilst the replacements are still attached to their original engines

I give this one about 30 minutes

Used to - then I dealt with them.
The percentage of them with major defects that they sent me was well in excess of 25%

When I orderd parts to fix them (At my own cost - I had given up on ever expecting the factory to support me) they abused me, Made up a bunch of lies about me then stopped talking to me altogehter. Still have that e-mail chain - it makes for entertaining reading as their rep tried to wiggle out of supplying parts (mainly because there are so many variations of the engines that they wouldn't know what they supplied and to whom).

Meanwhile they had given many other distributorships to people in my "sole distributorship" area (I guess they got confused with the fish)

Despite the efforts of some of the new distributors to show otherwise, they are still the same horse as always.

Now I use much better products (not frmo China - In fact, I don't even fly any of the alternatives I posted - but they are in a similar price range). Cost a bit more to start but the cost per flying hour is way less. Stress levels are much better too.

Well I can see your point...I had no idea it was so difficult to get parts in Australia...I have no problem on the east coast of USA

Luckily most don't need to bother with parts as they are a throw away product anyway.

Just wait until you do need parts and get supplied with parts for a different version to what you have - or even better, a reduction in quality (I am not going to mention things like prop hubs or carb blocks here - oops - already did ). Or when you get told that those parts are not available to you (or they just refuse to reply at all)

Time will show you what I refer to.

I learnt my lesson the hard way in dealing with this factory, sometimes those can be the best lessons learnt.

Unfortunately there are some great guys still dealing with the brand and some of them do try very hard to support the product. My prediction is that they will get burnt in the not too distant future as history has a way of repeating itself. Heck, one of those good guys even has been known to tell people that their engine isn't worth fixing "because the parts will be too expensive". If only those guys were aligned with a better company, they would be truly world beaters in the service delivery area.



Have a close look at the early parts of this thread (and others) - I WAS one of the guys who tried to make it work. I now know better and i am not alone in that knowledge.

Now that's funny!

I'm just keeping an eye on this thread because I have an RCGF 20cc rear carb that I bought from Henry.

Had issues at first, but runs great now, knock on wood.

Funny part is that I was e-mailing Henry for his help. He suggested what was wrong (not a big enough hole in the cowl, so the engine was not getting enough air) right off the bat, but I just did not believe him.

After cutting a larger hole in the cowl (and smacking myself upside the head), the engine runs great. Thanks Henry.

Not really but here is some info that might help you

1 - Plug Gap - 0.020" (0.5mm) - the same thickness as a #11 Hobby blade

2 - Check your timing is set at 28 - 30 degrees BTDC. The easiest way to do this is to find TDC, make a pencil (or scriber) mark across the hub and extend it to the crankcase - then measure the hub diameter and multiply that by 0.244 - that distance is how far before TDC the ignition should fire - make a mark there for future reference too (a bit like the old timing marks on a car engine)

3 - Check your needles are set at 1 3/4 turns out on both

If it isn't one of those 3 things, you will need to do some further investigation - there are many things that it could be. Feel free to PM me if you have more problems.

89 Oct should be fine - mix it at the recommended ratio for the oil you are using (I use 40:1 Redline from day one - others use 25:1 mineral or 32:1 Pennzoil Air cooled - there are other choices too).
